Architecture in a Nigerian town, Adazi Nnukwu, Anambra State has gone from Neolithic to International Style, from the use of clay products to concrete, steel and glass. The small town’s architecture that was predominantly mud buildings in the 1980s are today, covered with concrete and steel buildings and appeared International style. The term International Style covers buildings and architects of the formative decades of modernism. The unguided growth and explosion in the architecture of the small town has resulted in a confused architectural modules and difficult to classify by any standards. This paper aims to indicate the new trend and shift in the architecture of the small town from Neolithic to International Style or an undetermined style. It adopted content base analysis where the authors laid emphasis on the works of previous authors in the field. Adazi Nnukwu struggles with different styles of architecture for her post modern, urban to suburban architectural growth and has not embraced a particular architectural style, but the architecture of different historic periods including, but not limited to neoclassical architecture. The confusion in the classification of the town’s architecture has led to different opinions especially, with the fragmentation, non liner process of design, interest in manipulating ideas of a structure’s surface or skin, and apparent non Euclidean geometry non rectilinear shapes which serve to distort and dislocate some of the elements of their architecture that some considered, deconstructivism and has stuck and has now, in fact, come to embrace a general trend within their contemporary architecture.

Traditional building materials like wood, stone, clay, and thatch allow buildings to breathe by absorbing moisture and allowing it to evaporate. Traditional materials were chosen based on local availability and function. Modern materials like concrete, steel, and aluminum are also used in construction. A wide variety of natural and man-made materials can be used for building, each with their own advantages and disadvantages for things like strength, durability, insulation, and environmental impact. The choice of materials depends on the purpose and conditions of the building or structure.

The document discusses traditional earth construction techniques that have been used for over 9,000 years around the world, outlines different types of soils used for construction, and examines contemporary innovations that can help optimize earth as a building material and make it more viable for modern architecture. It explores how studying traditional methods and addressing issues like shrinkage can help earth construction be better utilized today through improved designs, materials, and techniques.
This document compares a traditional Sherpa house in Nepal to a modern sustainable building called the Himalesque. Both buildings are constructed primarily of locally sourced stone and are located at high altitudes near mountain ranges. While the Sherpa house relies on vernacular methods using materials like wood and clay, the Himalesque incorporates modern elements like glass to improve ventilation and lighting. However, it also respects vernacular values by using local labor and stone, and blending into the environment. The document concludes that in this case, the Himalesque successfully incorporated vernacular principles into a contemporary sustainable design.
Traditional Indian construction methods were highly energy efficient. Buildings were oriented and sited carefully, used thick insulating walls, incorporated verandahs, courtyards, and landscaping for natural cooling and ventilation. Roofs had slopes and waterproofing for drainage, and used locally available materials. Elements like domes, bungalow designs, and traditional attire required minimal energy for cooling or heating.
The major construction material that cost more are cement and gravel which
makes buildings costly. Palm kernel shells are locally available materials which can
be used in place of gravel. Previous works on the kernel shell shows that the strength
determined have met with the building requirements.
Concrete is the most common material used in construction, various research
work and experience gained shows that the quality and durability of concrete depend
mostly on the properties of its constituent, mix design, method of preparation, curing
etc. have their influence on it.
Tests results have shown that kernel shell concrete of mix ratio 1:2:4 has average
compressive strength of 5.6 N/mm2 at 14days curing while 12.47 N/mm2 at 28days of
curing.
Palm kernel shell produces a concrete with a lower compressive strength in
comparison with normal concrete with gravel.
The project in conclusion was a success as it took into consideration the economic
status quo of the population. This project help to provide new materials affordable for
the low income earners which helps in producing low cost houses and this does not
remove the criteria of performance for a material
The document discusses low-cost building materials and construction techniques. It begins by outlining common problems faced by developing countries like population growth, urbanization, and shortage of affordable materials. It then lists some alternative building materials that can help address these issues like fly ash bricks, hollow concrete blocks, bamboo, etc. These materials offer advantages over conventional materials like lower cost, better durability and energy efficiency. The document also discusses composites as low-cost building materials and how organizations like BMTPC in India promote research and development in this area. It provides guidelines for selecting low-cost materials for low-cost housing projects.

The Elementary Research of some Chinese Economically Valuable Construction Ma...IJRES Journal
This paper is just to talk about some ‘crazy’ construction materials. They are very strange and common to all of us, but quite applicable to our life shelters and useful for work-place’s conditions as many kinds of functional materials. Their names are easily understandable, like Fumo-sand (Fluorine-film-sand), glass-sand, they are only sands, and the crazy sands can create miracles for the world. They are ‘for-ever-green and golden’. Moreover, there are some other promising materials, such as bamboos, carbon-fiber-reinforced polymer (CFRP). And the idea of post-strengthening civil structures with carbon fiber reinforced polymer (CFRP) tapes was for the first time unveiled in an oral presentation at ETH Zurich in 1985 [1].The researcher will focus on researching them later on. These are not conceptual ones, but applicable and economically valuable things with much significance existing among the construction world. The researcher tries to think about them in an innovative-management-way, meanwhile, the cultivation of some construction materials will be quite helpful which can be used in the sight-seeing attractions’ constructions, perhaps they are not only potential and promising but also valuable and economical.
The document discusses the origins and development of brick as one of the oldest building materials used by humans. It describes how brick originated in ancient civilizations in Mesopotamia over 2500 years ago and spread through trade routes and conquests. Early bricks were made from sun-dried clay but firing techniques were developed to make them more durable. It provides details on the traditional process of making common field bricks involving extracting clay from pits, weathering it, mixing with organic binders, molding, and firing. Modern brick production employs more advanced technologies.

Standardization and Formulations of Calotropis ProceraYogeshIJTSRD
Plants growing in arid regions have elicited increased attention, because the hostile environment, in which these plants survive, forces them to develop chemical protective systems through adaptation which is rarely found in vegetation of other ecosystems. Furthermore, many of the plants grow in areas, where the dependence on traditional, plant based medicines over industrially produced pharmaceuticals persists to this day. The two plants, Calotopris Procera giant milkweed, also named C. Persica and Calotropis gigantea crown ower , have been used widely in traditional medicine in North Africa, the Middle East, and South and South East Asia. This has led to extensive research on the chemical constituents of the plants. Both plants are known to be sources of cardenolides, and newer research has yielded a number of interesting cancer active constituents. In addition, extracts of both plants have remarkable nematocidal, molluscidal and insecticidal activities. In many regions, the wood of Calotropis plants has been used as a building material and as a source of fuel. In addition, certain parts of the plants have been used as feed for livestock. In other regions, Calotropis plants are seen as invasive species that threaten local plant life and that due to their toxicity also pose a threat to grazing eld animals.

Review of the Diagnosis and Treatment of ParalysisYogeshIJTSRD
Paralysis is a complete loss of motor power in any muscle group. When paralysis affects all four extremities, it is called quadriplegia when it affects only the lower extremities, paraplegia and when it affects the extremities on one side of the body, hemiplegic. For this reason, the term paralysis is generally reserved for more focal, less stereotyped weakness, for instance, affecting all the muscles innervated by a peripheral nerve. Many different anatomical lesions and etiologies can cause paralysis and determine its treatment. Bikash Debsingha | Dr. Gourav Kr.

Automatic Query Expansion Using Word Embedding Based on Fuzzy Graph Connectiv...YogeshIJTSRD
The aim of information retrieval systems is to retrieve relevant information according to the query provided. The queries are often vague and uncertain. Thus, to improve the system, we propose an Automatic Query Expansion technique, to expand the query by adding new terms to the user s initial query so as to minimize query mismatch and thereby improving retrieval performance. Most of the existing techniques for expanding queries do not take into account the degree of semantic relationship among words. In this paper, the query is expanded by exploring terms which are semantically similar to the initial query terms as well as considering the degree of relationship, that is, “fuzzy membership- between them. The terms which seemed most relevant are used in expanded query and improve the information retrieval process. The experiments conducted on the queries set show that the proposed Automatic query expansion approach gave a higher precision, recall, and F measure then non fuzzy edge weights.

A New Proposal for Smartphone Based Drowsiness Detection and Warning System f...YogeshIJTSRD
This paper proposes a Smartphone based system for the detection of drowsiness in automotive drivers. The proposed system uses three stage drowsiness detection technique. The first stage uses the percentage of eyelid closure PERCLOS which is obtained by capturing images with the front camera of the Smartphone with a modified eye state classification method. The system uses near infrared lighting for illuminating the face of the driver during night driving. The second step uses the voiced to the unvoiced ratio VUR obtained from the speech data from the microphone, in the event PERCLOS crosses the threshold. The VUR is also compared with a threshold and if it is a value greater than that of the threshold, it moves on to the next verification stage. In the final verification stage, touch response is required within the stipulated time to declare whether the driver is drowsy or not and subsequently sound an alarm. To awake the driver, a vibrating mechanism is done and also the live GPS location is also sent to an emergency contact. We have studied eight other reference papers for the literature review. The system has three advantages over existing drowsiness detection systems. First, the three stage verification process makes the system more reliable. The second advantage is its implementation on an Android smart phone, which is readily available to most drivers or cab owners as compared to other general purpose embedded platforms. The third advantage is the use of SMS service to inform the control room as well as the passenger regarding the loss of attention of the driver.

Data Security by AES Advanced Encryption StandardYogeshIJTSRD
Now a days with the rapid development of multimedia technologies, research on safety and security are becoming more important. Multimedia data are generated and transmitted through the communication channels and the wireless media. The efficiencies of encryption based on different existing algorithms are not up to the satisfactory limit. Hence researchers are trying to modify the existing algorithm or even develop new algorithms that help to increase security with a little encryption time. Here in this paper, we have furnished a new technology to modify the AES algorithm which gives more security with a little encryption time and which can be used to encrypt using 128 bit key. Theoretical analysis on the proposed algorithm with the existing reveals the novelty of our work. Here we have proposed a technique to randomize the key and hidden the key data into an encrypted digital image using the basics concept of cryptography and also using the concept of digital watermarking, the concept of key hide has also been encrypted. We have also proposed a new technique to reposition the pixels to break the correlation between them. So, the proposed scheme offers a more secure and cost effective mechanism for encryption. Next on the AES criteria list good performance. Widespread market adoption will require reasonably good performance on a variety of platforms, ranging from easy tocrack smart cards to the largest servers. Good algorithm performance includes speed for the encryption and decryption process as well as the key schedule.

Evaluation of Different Paving Mixes Using Optimum Stabilizing ContentYogeshIJTSRD
Bituminous mixes are most commonly used all over the world in flexible pavement construction. It consists of asphalt or bitumen used as a binder and mineral aggregate which are mixed together, laid down in layers and then compacted. Under normal circumstances, conventional bituminous pavements if designed and executed properly perform quite satisfactorily but the performance of bituminous mixes is very poor under various situations. Today’s asphaltic concrete pavements are expected to perform better as they are experiencing increased volume of traffic, increased loads and increased variations in daily or seasonal temperature over what has been experienced in the past. In addition, the performance of bituminous pavements is found to be very poor in moisture induced situations. Considering this a lot of work has been done on use of additives in bituminous mixtures and as well as on modification of bitumen. Research has indicated that the addition of polymers to asphalt binders helps to increase the interfacial cohesiveness of the bond between the aggregate and the binder which can enhance many properties of the asphalt pavements to help meet these increased demands. However, the additive that is to be used for modification of mix or binder should satisfy both the strength requirements as well as economical aspects.

Neolithic architecture. Neolithic architecture is the
architecture of the Neolithic period. Although many
dwellings belongs to all prehistoric periods and also some
clay models of dwellings have been uncovered enabling the
creation of faithful reconstructions, they seldom include
elements that may relate them to art. Some exceptions are
wall decorations and that equally apply to Neolithic and
Eneolithic rites and art (Historical Development of
Architecture, 2020).

In some areas, they covered wood framed structures with
mud while same was not the case in certain areas. The mud
structures are commonly known as Uno Atani in Igbo land
(spare grass house, Raffia palmfrond,palmfrondhouse,etc).
The mud buildings are covered and roofed with all kinds of
plant leaves, depending on the area, but mostly used are,
raffia palm fronds, Ata (sharpmouthedandaggressivegrass,
carefully weaved together). At that time, most of the huts
(mud buildings) in developing countries were built with
mostly clay soil mixed with water, hand compressed and
straight from the ground around the area of the building to
the building and roof, covered with native or local materials
including specially made leaves and grasses.
Mud can be made into mud bricks, also called adobe, by
mixing mud with water, placing the mixtureintomouldsand
then allowing it to dry in open air. Straw is sometimes used
as a binder within the bricks, as it makes them composite.
When the brick would otherwise break, the straw will
redistribute the force throughout the brick, decreasing the
chance of breakage. Such buildings must be protected from
groundwater, usually by building upon a masonry, fired
brick, rock or rubble foundation, and also from wind-driven
rain in damp climates, usually by deep roof overhangs. In
extremely dry climates, a well-drained flat roof may be
protected with a well-prepared (puddled) and properly
maintained dried mud coating, viableasthemudwill expand
when moistened andso becomemore waterresistant.Adobe
mud bricks were commonly used by the Pueblo Indians to
build their homes and other necessary structures. Mud that
is mostly clay, or a mixture of clay and sand may be used for
ceramics, of which one form is the common firedbrick.Fired
brick are more durable but consume much more energy to
produce. Stabilized mud (earth, soil) is mud which has had a
binder such as cement or bitumen added. Examples are
mudcrete, landcrete, and soil cement (Mud, 2019).
With the improvement and growth in the economy of
Nigeria, came the introductionofcement.AccordingtoTypes
of Houses in Nigeria (2014), the history of cement
production in Nigeria dates back to 1957. With the
introduction of cement, Nigerians gradually moved away
from mud buildings (plate 2) and used mostly concrete
blocks made with cement and sand (sandy soil). In some
cases, mud building were plaster with cement (plate
3).According to Types of Houses in Nigeria (2014), the mud
houses were transformed into beautiful edifices, people
began building it with plan, with different rooms and even a
sitting room, painting it and even bringing in electricity.
Some of the mud buildings were plastered and covered with
cement (plate 3).

Even with the introduction of cement and blocks, mud was
still used in the form of bricks. As indicated by the Types of
Houses in Nigeria (2014), the brick houses have taken the
center stage in Nigeria now as the mud and thatched houses
are referred to as ancient or primitive houses. Bricks are
compressed clay soil specially made in form of small blocks.
According to Neufeldt and Guralnik (1994),brick isa pieceof
baked clay. A substance madefromclaymouldedintooblong
block and fired in a kiln or baked in the sun, used in building
and paving. Most times, the compressed clayis burnt in

special ovens depending on the area, availability of the
facility andor, dried underthesunbeforeusage.Thesebricks
are still used in the western world, especially in building
expensive homes. In Maryland, USA, the Maryland Masonry
Institute, now, the Mid-Atlantic Masonry Association
(MAMA) did a lot of work with bricks and constantly
promoting their products and marketing innovative works
done with bricks. The Mid-Atlantic Masonry Association
(MAMA) was formedin2013 todisseminateinformationand
promote the use of masonry in all aspectsinthemarketarea.
The program of work creates a targeted approach to
providing information and strategiestopromotemasonry as
the premier building system (Mid-Atlantic Masonry
Association, 2014).
Today, and in Nigeria, builders are gradually going back to
mud buildings although, under a new name, Hydra form
blocks (plate 4). Hydra form gained its name from a South
African company, one of the world leading masonry
construction and the manufacturers of Hydraulic Block
machines, championing and producing both the machines
used in producing the products and the products. Now,
almost all compressed clay soil blocks are commonlyknown
as Hydra form blocks. Although the industry is not well
marketed in Nigeria, the products seem to be gaining
attention especially, in estate developments and rural
housing schemes in poor neighborhoods and urban poor
settlements (ABD Digest, 2014).
Hydra form block production does not require special skills
and sophisticated training and may encourage the use of
quacks and boost laziness. Poor mixing of the materials
could immensely impact the products and bad clay soil with
plant roots could leave holes in the product and when
decayed, may affect the strength of the structure especially,
when exposed to heavy rain or water logged area. Using the
product in erecting a fence only requires stacking the
products together on top of each other and aligning their
binding channel (plate 4).

During the research for this article, the authors visited
Coojike Hydrant, a small Hydra formplantinAdazi-Nnukwu,
Anaocha Local Government Area,Anambra State,Nigeria.An
expert in Compressed Clay Soil (Hydra form) indicated that
they add cement to their products to strengthen them.
According to him, one bag of cement could produce up to
ninety tablets (as described in that industry) of Hydra form
blocks and they can mould any form they want especially,
the wall copings (plates 4 to 8).
According to the Hydra form expert, they produce Hydra
form blocks in any colour their client desires. For the black
ones (plate 6), they would only add black carbon, a powdery
product generally known as carbon. Carbon has different
colours, clay soil has different colours, depending on want
and geographic area, they would produce according to one’s
desire. The expert further indicated that the products are
relatively cheap and an inexpensive way to build.

The company’s expert indicated that their machines were locallymanufacturedand eachmouldstwotabletsata timewhilethe
conventional machines mould one at a time (plates 9 to 11). He further indicated that they are currently constructing a
moulding machine that could mould twenty tablets at a time and also, a machine that could mould interlocking stones of any
design.

The products are environmentally friendly and could be produced anywhere, even on the job sites and the machines are
portable, easily moved around (plates 9 to 11). The products are fast and easy to produce and the usage is equally easy. Both
the machines and the products are cost effective and create innovative ways of building, especially, with the interlocking dry
stacking provisions (plate 7).
With the introduction of Hydrform block products in Adazi-Nnukwu, the model and trend in the architecture and buildings
changed. The people used the products in different ways and patterns in building their houses. Some try to replicate the 1940
buildings where mud and bricks were achitecturally expressed. Fundermentally, the small town has seen a shift in her
architecture, a shift that is embracing urban architecture becauseoftheavailabilityoflocal buildingmaterialsandtheexposure
of her citizens to outside world’s architecture.
Aim
The primary aim of this paper to indicate and point to a new trend and shift in the architecture of the small town, Adazi-
Nnukwu, Anocha Local Government Area, Anambra State, Nigeria from the Neolithic to International Style architecture.
Methodology
It adopted content base analysis where the author laid emphasis on the works of previous authors in the field of architecture
and historical development in architecture, in buttressing their points.
Findings
With the technology and creative ways of using cement and interlocking hydraform blocks, village architecture, especially in
Adazi-Nnukwu, that was predominantly mud buildings changed in the 1970’s to concrete buildings (Plate 12), what could be
considered Early Mordern Architecture. Early Modern Architecture began with a number of building styles with similar
characteristics, primarily the simplification of form and elimination of onrnaments, thatfirstarosearound1900.Bythe1940s,
these styles had largly consolidated and been identified as the International Style (Historical Development of Architecture,
2020).
Given, sprinckles of mud buildings still exist here andthereinsomevillageshowever,inAdazi-Nnukwu,a small towninAnocha
Local Government Area, Anambra State, Nigeria, one could hardly see a mud building as is the case in plates 2 and 3. With the
abundance of cement and concrete, individuals who could afford them built their homes with concrete in the late 1970s and
1980s (plate 12) adopting International Style, but that did not last long.

With the increase in importation of building materials in Nigeria, advancement and changes in building technology, Nigerians
adopten the wastern style architecture, greatly influenced by the use of stucco, tiles and bricks in finishing their buildings,
adopting the Expressionist Architecture. Exprosionist Architecture was an architectural movementthatdeveloped inNorther
Europ during the first decades of the 20th century in parallel with the expressionist visual and performing arts. The style was
characterised by early-modernist adoption of novel materials, formal innovations, and very unusal massing, sometimes
inspired by natural biomorphic forms, sometimes by the new technological possibilities offered by mass production of brick,
steel and glass (Historical Development of Architecture, 2020). As a result, a lot ofconcreteblock buildingswerebuiltinAdazi-
Nnukwu and that revolutionized the building development in that town. Today, some of those much admired buldings of the
1970s and 1980s are being knocked down and replaced with post modern buildings, embracing the use clay products
inovatively transformed into brick veneers, local tiles, Hydraform blocks, etc (Plate 13). The village is witnessing a shift in
architectural movement, from the mud buildings of the 1940s, 1950s, 1960 and 1970s to urban architecture of 2019. This
architectural movement could be classified as a shift from the western world’s architecture of the urban areas in Nigeria to
suburban and or, village architecture in Adazi-Nnukwu, yet, International Style.

The International Style was a major architectural trend of the 1920s and 1930s. The term usually refers to the buildings and
architecture of the formative decades of modernisim, before World War ll. The term had its origin from the name of a book by
Henry-Russel Hitchcook and Philip Johnson which identified, categorised and expanded upon characteristics common to
modernism across the world. As a result, the focus was more on the stylistic aspects of modernism.Thebasicdesign principles
of International Style thus constituted part of modernism. The ideas of Modernism were developed especially in what was
taught at the German Bauhaus School in Weimar (from 1919), Dessau (between 1926-1932) and finally Berlin between1932-
33, under the leadership first of its founder, Walter Cropus, then Hannes Meyer and finally Ludwig Mies van der Rohe.
Modernist theory in architecture resided in the attempt to bypass the question of what style a building should be built in, a
concern that had overshadowed 19th-century architecture, and the wish to reduce form to its most minimal expression of
structure and function. In the United States, Philp Johnson and Henry-Russel Hitchcook treated thisnew phenomenonin1931
as if it represented a new style – the International Style, thereby misrepresenting its primary mission as merely a matter of
elimination traditional ornaments. The core effort to pursue Modern architecture as an abstract, scientific programme was
more faithfully carried forward in Europe, but issues ofstylealwaysovershadoweditsstricterandmorepuritangoals,notleast
in the work of Le Corbusier (Historical Development of Architecture, 2020).
The architecture in Adazi-Nnukwu is now, in a cross road between the Classical Greek and Modernistic Movement.Mostofthe
buildings are adopting classical columns especially, the Corinthian columns (panel 1),supportingtheargumentthat,theissues
of style always overshadowed its stricter and more puritangoals,notleastinthe work ofLeCorbusierasindicated above.From
2010 to date, the architecture of Adazi-Nnukwu has tremendously changed and in panels 1 to 4,arethetypical examplesofthe
town’s architecture.

Panel 2 shows the interior details of the architecture of the building in panel 1. The building is still under construction, butthe
details are clear. The elements of the buildings are not hidden. The concept, proportion of the bays and the use of expressive
columns in balancing the front elevation are unique and quintessential. The majority of the interior spaces were covered with
Plaster of Paris (POP) decorative designs. Plaster of Paris is quick-setting gypsum plaster consisting of a fine white powder
(calcium sulfate hemihydrate), which hardens when moistened and allowed to dry.Knownsinceancienttimes,PlasterofParis

However, with the innovative architectural explosion in Adazi-Nnukwu, the building was in 2019 renovated (panel 3),
embracing the use of all sorts of modernized building materials not limited to POP, ceramic tiles, stone veneer, brick veneer,
and beautifully landscaped with outdoor relaxation facilities for the comfort of the owners and their guests. It is an
architectural expression and explosion not before seen in any of the Nigerian villages.

growth in the town.
It is not in doubt, that, Adazi-Nnukwu has struggled with different styles of architecture for her post modern, urban to
suburban architectural growth and has not embraced a particular architectural style, but the architecture of different historic
periods including, but not limited to neoclassical architecture. Plate 15 is a building under constructionthatcould beclassified
neoclassical architecture and one wonders how to classify the architectureofthetown? Theshiftto neoclassical architectureis
conventionally dated to the 1750s. It first gained influence in England and France; in England, Sir William Hamilton’s
excavations at Pompeii and other sites, the influence of the Grand Tour and the work of William Chambers and Robert Adam,
was pivotal in this regard. In France, the movement was propelled by a generation of French art students trainedin Rome,and
was influenced by the writings of Johnson Joachin Winckelmann. The style was also adopted by progressive circle in other
countries such as Sweden and Russia. Federal-style architecture is the name for the classicizing architecture built in North
America between 1780 and 1830, and particularly from 1785 to 1815. This style shares its name with its era, the Federal
Period. The term is also used in association with furniture designintheUnitedStatesof thesametimeperiod.Thestylebroadly
corresponds to the middle-class classicism of Biedermeier style in the German-speaking lands, Regency style in Britainandto
the French Empire style. In Central and Eastern Europe, the style is usually referred to as Classicism (German: Klassizismus,
Russian: Knaccnunem), while the newer revival styles of the 19th century until today are called neoclassical (Historical
Development of Architecture, 2020).
In furtherance to the confusion that the architecture of Adazi-Nnukwu could not be classified, during the research for this
paper, a villager indicated that the townwentfrom mudarchitecturetoDeconstructivism.AccordingtoHistorical Development
of Architecture (2020), Deconstructivism in architecture is a development of postmodern architecture that began in the late
1980s. It is characterized by ideas of fragmentation, non-liner process of design, an interest in manipulating ideas of a
structure’s surface or skin, and apparent non-Euclidean geometry(non-rectilinearshapes)whichservetodistortanddislocate
some of the elements of architecture, such as structureandenvelope.ThetermDeconstructivismhasstuck andhasnow,infact,
come to embrace a general trend within contemporary architecture.

Conclusion
Architecture in Adazi-Nnukwu prior to 1950s was mostly
buildings, built with mud. After the 1950s and early 1960s,
with the introduction of cement, mud buildings were
plastered with cement and decorated according to village
interest and cultural beliefs. From the late 1950s came the
use of concrete block buildings up till today. However, with
the advancement in technology, growth and exposure of the
people, the contemporary architecture of the small town is
changing to International Style although, bracing different
architectural periods. The use of mud products has
resurfaced in the area and especially, Hydraform blocks and
brick panels. The simplification of building forms and the
elimination of ornaments have given rise to Modern
architecture and in some quarters, International Style.
Recommendations
Adazi-Nnukwu architecture today is fundamentally
International Style, partly because of the exposure of the
people from the town, their overwhelming interest in
architectural growth, architectural tourism and interest in
the historic preservation of their culture as a result, this
paper recommends the documentationofthetown’shistoric
architectural growth and developments. The town is fast
getting too urbanized architecture-wise and adequate
measures should be put -in place to control the speedy
growth and properly plan the infrastructure of the area to
avoid unnecessary destruction of the natural environment
that might result in erosion problems, building of unusable
and abandoned buildings and the creation of unsustainable
environment.
