MAXIMISING GREEN SAPCES IN A BUILDING COMPLEX THROUGH ALTERNATIVE LANDSCAPE DESIGN ELEMENTS 2
In today's urbanized world, the availability of open green spaces within building complexes has become increasingly limited. However, there is a growing recognition of the importance of
incorporating nature and greenery into our built environments. As a result, alternative landscape design elements such as roof gardens and vertical gardens have emerged as innovative
solutions to maximize green spaces within a building complex.
Roof gardens involve the transformation of otherwise unused rooftops into lush green spaces. By utilizing this often overlooked area, building complexes can create vibrant gardens that not
only enhance the aesthetic appeal but also offer a range of environmental and social benefits. On the other hand, vertical gardens involve the cultivation of plants on vertical surfaces, such
as walls and facades. This vertical greening technique offers a unique opportunity to transform bare walls into living, breathing ecosystems.
The aim of this topic is to explore the concept of maximizing green spaces in a building complex through the implementation of alternative landscape design elements, specifically focusing
on roof gardens and vertical gardens. By delving into the potential benefits and challenges associated with these green interventions, we can better understand their role in creating
sustainable and liveable environments.

ROOF GARDEN
A roof garden is a garden on the roof of a building. Besides the decorative benefit, roof plantings may provide food, temperature control, hydrological benefits,
architectural enhancement, habitats or corridors for wildlife, recreational opportunities, and in large scale it may even have ecological benefits
HISTORY OF ROOF GARDEN
The Ziggurats Of Ancient Mesopotamia
The earliest known record of roof gardens are the ancient ziggurats of Mesopotamia. These massive stone structures were built between 4,000 – 600 BC. A
series of stairs along the outside perimeter of the stepped pyramid provided access to the various tiers of the structure. As there were no interior rooms, trees
and flowers on each terrace of the enormous ziggurats would provide a cool, shady place for the visitor to rest from the blazing Babylonian sun.
The Hanging Gardens Of Babylon
The Hanging Gardens of Babylon are one of the Seven Wonders of the Ancient World and perhaps the most famous of roof gardens. King Nebuchadnezzar, a
famous general in his time, built the Hanging Gardens for his wife, Amytis, who longed for her mountainous homeland of Media. The ziggurat had a 400
ft2 base, with landscaped terraces eventually reaching the grand roof garden at the top, 75 feet above the ground. It was an engineering marvel, a living mountain
in the middle of a desert. The terraced layout explains the phrase “hanging garden,” where the vegetation hung over the walls to the level below.
The Villa Of Mysteries, Pompeii
Little was known about Roman day to day life until the accidental discovery of the city of Pompeii, near Naples, in 1749. Pompeii was covered in thirteen to
twenty feet of ash and pumice from the volcanic eruption of Mt Vesuvius in AD 79, preserving almost perfectly for all time the people, activities, and lifestyle of
the Roman town like a candid snapshot from a Polaroid Instamatic. From this snapshot archaeologists have discovered that roof gardens were an essential part
of Roman life
Palazzo Piccolomini, Pienza, Italy
The Palazzo Piccolomini was the private summer residence of Pope Pius II. The palazzo was part of a wider development plan Pope Pius envisaged for Pienza,
his home town, which was in a dreadful state. The scheme for Pienza is one of the first examples of Renaissance town planning and is thought to be the earliest
example of town planning in Europe. The project has been celebrated as a successful creation of an ideal town, a masterpiece of human creative genius.
Norwegian Sod Roofs
Not all roof gardens were designed to impress. Sod roofs, roofs topped with soil and planted with grasses and other plants to stabilize the earth on the roof, were
part of the Norwegian vernacular. Sod roofs provided insulation, mitigated damage to the roof from the rain, prevented the roof from rotting, and the root system
bound and strengthened the roof structure.
Wright, Le Corbusier, & Modern Architecture
Architecture changed dramatically in the early 20th century. Modernists such as Frank Lloyd Wright and Le Corbusier broke free from the bonds of historical
architecture, introducing a completely new form of design that had no reference to the past. Le Corburiser’s Cinq Points de l’Architecture Moderne became the
new model for architectural design and theory. The 5th Point, the roof garden or terrace, was a flat roof intended to be an outdoor living room, a place to
exercise and to enjoy the fresh air, rather than a literal garden with plants and trees.

TYPES OF ROOF GARDEN
1. INTENSIVE ROOF GARDEN
Low-maintenance Green Roof Garden That Has A Thin, Light-weight Growing Medium. This Type Of Green Roof Is Characterized By Its Vegetation, Which
Is Often Limited To Sedums, Mosses, Herbs, Small Plants And Flowers, Desert Grasses, And Succulents. Because It Has A Growing Medium Depth Of
Around 3 To 6 Inches, An Extensive Green Roof Is Easier To Install And Cost-efficient, And Generally Doesn’t Require An Irrigation System To Survive. It
Is Ideal For Storm Water Management For Flat Or Low-sloped Roofs And Retrofits
2. EXTENSIVE ROOF GARDEN
A Rooftop Garden Or Sky Park Than Anything Else. This Roof Garden Design Is Characterized By Deep Soils That Have A Growing Medium Depth Of
More Than 6 Inches. A Variety Of Vegetation Can Be Grown In An Intensive Roof Garden, From Small To Large Plants, Shrubs, Groundcovers, And Even
Small Trees
3. SEMI INTENSIVE ROOF GARDEN
Boasts A Mix Of Both The Intensive And Extensive Green Roofs. It Is Characterized By A Growing Medium Depth Of Around 6 To 12 Inches To Host A
Much Richer Ecology. Greenery In This Type Of Rooftop Garden Consists Of Small Plants, Grasses, Herbs, Small Shrubs, And Groundcovers That Require
Occasional Irrigation And Moderate Maintenance.

COMPONENTS OF ROOF GARDEN
LAYERS OF ROOF GARDEN
Roof garden employs a multilayer system, including a waterproof membrane, drainage layers, geotextile layer, specialized soil medium, soil stabilizer, and a selection of appropriate plant
species and varieties that best tolerates the often extreme environmental conditions found in a rooftop setting.
WATER PROOFING MEMBRANE
Water proofing is the area that is responsible for the most litigation. The structure of the building will determine water proofing design
and installation. There are many kinds of waterproof membrane. Some membranes have added root retardants which acts as root barrier
DRAINAGE LAYER
The purpose of drainage systems is to facilitate water runoff from the roof to prevent structural collapse and
plants from drowning while retaining enough moisture to support plant life. The roof drainage should be
integrated into the building drainage system. Drainage facilities must be capable of collecting both overflow
from the drainage course and surface water from the vegetation support course and of conveying it away.
The drainage system should be permanent and cover the entire roof area. Water retention may be desirable
as an environmental mandate. This may require:
•Increased drainage cup size (versi cells)
•A water retention layer
•Engineered growing medium

FILTER SHEET
Drains water and retains the growing media and roots
GROWING MEDIUM
Growing medium selection is critical to the long and short term success of a green roof. The following factors should be considered for selecting
growing medium
• Load bearing capacity
• Slope
• Climate
• Drainage
• Plant species
.
Natural mineral components of roof garden substrate include sand, clay, lava, pumice, gravel, etc. Artificial or modified mineral components such as perlite, vermiculite, etc., are used in
roof garden. Organic materials such as peat, composts are also added to the substrate formulation. The light weight soil amendments reduce substrate weight and support plant growth. The
pH should be 5.5 -8. the air content and water storage capacity should be more than 20% and 45% by volume
PLANT SELECTION
Plant species selection is dependent on a number of factors:
• Maintenance investment and resources
• Aesthetics
• Function
• Climate and weather
• Structural load bearing
• Roof type
• Plant growth rate and nutrient demand
• Supply and availability
Different depth of the substrate supports different vegetation. For example, in extensive green roof, moss and sedum can be grown in 4 – 10 cm depth and moss, sedum and herbaceous
plants can be grown in 5 – 11 cm depth. In a depth of 15 – 25 cm, grass and herbaceous plants can be grown.
In roof garden, lawn shrubs, coppices and trees can be grown. Trees can be grown in more than 50 cm depth of the growing medium.
ADDITIONAL FEATURES
• Certain individual varieties, particularly evergreens are not completely winter
hardy and where the plant cover is of limited density.
• Shrubs and coppices in exposed positions must be able to withstand the wind
• Certain plants are sensitive to reflected light and thermal build up.
• All vegetation is sensitive to airborne chemical and exhaust contamination, also
to warm and cold air emissions.

IRRIGATION
• Additional watering should be carried out regularly at roof garden. This may be provided by using a hose, sprinkler type or drip type hoses, or overhead irrigation system or automated
watering system.
MERITS OF ROOF GARDEN
• Aesthetic effects
• Acts as natural insulation for hot and cold air and a save energy for your building
• Reduces CO2 levels and increases oxygen and improved air quality
• Improves thermal insulation and energy efficiency
• Provides protection to buildings from adverse temperature and hence improves the life expectancy of the buildings
• Mitigate urban island heat effect
• It holds rain water, providing food and shelter for wildlife
DEMERITS OF ROOF GARDEN
• Existing structural support may not be sufficient
• May require water supply
• May increase insurance cost
VERTICAL GARDEN
Vertical Gardening is a special kind of urban gardening suitable to small spaces, particularly for decorating the walls and roofs in various styles. This is an
alternative method for gardening by expanding the scope of growing plants in a vertical space.

HISTORY OF ROOF GARDEN
Hanging gardens of Babylon
One of the Seven Wonders of the Ancient World, the Hanging Gardens of Babylon were built in 600 BCE by Nebuchadnezzar for his wife Amytis (though
this is disputed) and are one of the first, and most famous, examples of a creative approach to decorative, wall-based gardening. The Hanging Gardens did not
actually hang at all. They were made up of a simulated mountain with rooftop gardens. They would have likely been multi-level terraces supported by baked
brick columns. These columns would have been filled with dirt to allow large plantings and trees to root and grow. The effect of the plants hanging down over
the years likely gave the effect of a lush mountain landscape, seemingly hanging in mid-air. It would have been spectacular to behold
Ancient Vineyards
Ancient Greece had a thriving wine industry, and although they were planted horticulturally, vines had multiple uses and were often planted as illustrated above;
practically, for shade, but also in an aesthetically pleasing manner. “The first vertical gardens date back to 3000 BCE in the Mediterranean area. Grape vines (Vitis
spp.) were, and continue to be, a very popular food crop for people in the region, so they were commonly grown in fields, homes, and gardens throughout the area.
Sometimes vines were planted for the purpose of growing food, and others to simply provide shade in places where planting trees was not an option
Ivy On British Mansions
There’s no exact time frame for this, but ivy, roses, honeysuckles and other creepy, crawly plants have been growing over ancient British mansion for centuries.
Though not what we would understand a vertical garden to be today, since technically a vertical garden needs to have a growing medium it’s growing over, not
just soil at the base, they definitely inspired some of the vertical aesthetics we are seeing today. A popular example is Llanwenarth House, pictured here. This
beautiful mansion was built in the 16th century, and inspired the hymn “All Things Bright and Beautiful.” Interestingly, ivy was proven in an Oxford study to
actually protect the walls of some of these ancient homes.
Professor Stanley Hart White, The “Inventor” Of The Vertical Garden
The first hint of a vertical garden as we know it was patented in 1938 by Stanley Hart White. Then named “Botanical Bricks” by their maker, Stanley Hart White. He
was a professor of Landscape Architecture at the University of Illinois from 1922 and developed prototypes in his backyard in Urbana, Illinois.
Patrick Blanc, Populizer Of The Green wall
Though not the inventor of the green wall, Patrick Blanc brought the concept to popular imagination and turned it into the concept we know today, both
decoratively, and for urban farming, after a hugely successful installation in 1986 of a huge indoors green wall. “His first installation of a green wall was in
1986 at the Museum of Science and Industry in Paris, and was followed a decade later by the Foundation Cartier also in Paris,” writes Vertigro. Blanc was an
ecological engineer and tropical plant specialist, and his creative use of green walls inspired people for decades to come.
Some form of vertical gardening has been around for almost as long as people have been planting, and in modern times has turned to science (think massive indoor urban farms
using hydroponics) and improved system design. An example of this (if you’ll allow us!) is GrowUp’s system, which uses a clever (though ancient) design - the honeycomb - which allows
for greater flexibility with the system’s layout, as well as a more compact design. We have also spent years updating our hardware, and made sure we used leak-free irrigation, light plastic
hardware, a looped irrigation system and water-absorbent bags for each pot.

TYPES OF VERTICAL GARDEN
GREEN FACADES
• Green facades are a type of green wall system in which climbing plants or cascading groundcovers are trained to cover specially designed
supporting structures.
• Plants are either grown in the ground or in the elevated containers where they are watered and fertilized
Green facades are a type of green wall system in which climbing plants or cascading groundcovers are trained to cover specially designed
supporting structures. Rooted at the base of these structure, in the ground, in intermediate planters or even on achieving full coverage. Green
facades can be anchored to existing walls or built as freestanding structure, such as fences or columns
LIVING WALLS
• Living wall system composed of pre-vegetated panels, vertical modules or planted blankets that are fixed vertically to a structural wall or frame. These panels can
be made of plastic, expanded polystyrene, synthetic fabric and support a great diversity of plants species ( eg: a lush mixture of ferns, ground covers, perennials
and edible plants).
• Constructed from pre-vegetated panels, vertical modules or planted blankets (vegetated mat wall) that are fixed to structural framework or to a wall Made from
steel framework, plastic, expanded polystyrene and synthetic fabric to support a variety of diversity and density of plant species Tend to require more maintenance
such as fertilizer and water than green facade systems that are planted into the ground
Modular green wall : Vertical Garden Modules is made up of recycled poly propylene material. It has attractive look, highly durable in nature and it can be easily
installed. It provides instant solution for making garden in your residing place.
Green wall cups:
• Frame/ Supporting panel
• Easily detachable cups/pot
Vegetated mat wall : This system, pioneered by Patrick Blanc, is composed of two layers of synthetic fabric with pockets filled with the plants and growing media
.The fabric walls are supported on a framework and backed by a waterproof membrane against the building wall Nutrients and water are delivered through an
irrigation system at the top of the wall

Green wall system vary greatly in their design and construction from DIY projects To modular green wall systems. This heading provides information on
• Structures and components for green wall system
• Suitable plants
• Growing media
• Irrigation and plant nutrition
• General considerations for green walls

CHOOSING THE PLANTS
The best plants for vertical gardens are dense, compact and low growing. Make sure you choose species that suit the aspect of the wall on which they’ll be growing. A wall drenched in sun,
for instance, will need a selection of fairly drought-tolerant plants, whereas a shady spot – perhaps under a pergola or verandah – will require a selection of shade lovers, such as ferns. Also
bear in mind that the bottom of the unit will hold more moisture than the top, so consider this when you’re deciding what to plant where.
Apart from aesthetic preferences and the plants ability to grow in a soilless, vertical location; the selection of plants is based on several factors, for example: What is the local climate like
(minimum temperature especially important to know)? How much sun exposure is each area of the surface receiving and how does it change during the year? Is there any particular micro
climate — such as high buildings creating strong winds along a wall? Understanding the prevailing growing conditions is essential to make the right decision when choosing plants.

GROWING MEDIUM
Requirements:
• Weightless media
• High Water holding capacity
• High Nutrient holding capacity
• Good Porosity
• Neutral pH
Cocopeat, Perlite, Sphagnum moss, vermiculite, vermicompost, shredded bark and leaf molds are the common media combinations used. Soil in not used since it increases the weight of the
green walls.

There are three types of growth media used in living walls:
• Loose media
• Mat media
• Structural media.
1 LOOSE MEDIUM
Walls Tend To Be "Soil-on-a-shelf" Or "Soil-in-a-bag" Type Systems. Loose Medium Systems Have Their Soil Packed Into A Shelf Or Bag And Then Are Installed Onto The Wall. These
Systems Require Their Media To Be Replaced At Least Once A Year On Exteriors And Approximately Every Two Years On Interiors. Loose Soil Systems Are Not Well Suited For Areas
With Any Seismic Activity. Reparations Are Only Achieved By Re-stuffing Soil Into The Holes On The Wall, Which Is Both Difficult And Messy. Loose-soil Systems Should Not Be Used
In Areas Where There Will Be A Lot Of Public Interaction As They Are Quite Messy And Lose Their Soil Little By Little Over Time. Loose-soil Systems With Physical Media Erosion
Systems Are Well Suited For All Green Wall Applications.
2 MAT TYPE SYSTEM
Tend To Be Either Coir Fiber Or Felt Mats. Mat Media Are Quite Thin, Even In Multiple Layers, And As Such Cannot Support Vibrant Root Systems Of Mature Plants For More Than Three
To Five Years Before The Roots Overtake The Mat And Water Is Not Able To Adequately Wick Through The Mats. The Method Of Reparation Of These Systems Is To Replace Large
Sections Of The System At A Time By Cutting The Mat Out Of The Wall And Replacing It With New Mat. This Process Compromises The Root Structures Of The Neighbouring Plants On
The Wall And Often Kills Many Surrounding Plants In The Reparation Process.
3 STRUCTURAL MEDIA
Are Growth Medium "Blocks" That Are Not Loose, Nor Mats, But Incorporate The Best Features Of Both Into A Block That Can Be Manufactured Into Various Sizes, Shapes And
Thicknesses. These Media Have The Advantage That They Do Not Break Down For 10 To 15 Years, Can Be Made To Have A Higher Or Lower Water Holding Capacity Depending On The
Plant Selection For The Wall, Can Have Their Ph And Ec's Customized To Suit The Plants, And Are Easily Handled For Maintenance And Replacements. They Are The Most Robust Option
For A Living Wall For Both Exterior Applications And For Interior Applications. They Are Also The Best Choice In Areas Where High-winds, Seismic Activity Or Heights Need To Be
Addressed In The Design. Structural Media Are Superior To The Other Media For Their Longevity And High-level Of Performance In A Variety Of Circumstances. Depending On The
Installation, They Do Tend To Be More Expensive To Install, But Lower Cost To Maintain.
IRRIGATION AND PLANT NUTRITION
Green walls cannot be sustained without irrigation. Interruptions to the water supply are a common cause of plant failure on green walls. Systems designed with inbuilt irrigation should
mitigate plant losses due to inconsistent moisture management, although errors can still occur. Automated, remotely controllable irrigation systems are used for walls in high profile
locations, or in situations where access is challenging. Note that the quality, design and costs will vary between different systems. The most sophisticated systems enable the maintenance
supervisor to keep track of the automated performance of the system, including the volume of irrigation delivered, its frequency, substrate moisture content, as well as pH and nutrient levels
in the water supply. The settings can be overridden if needed; for instance, the frequency or duration of irrigation cycles may be increased on hot days. In hydroponic systems, plant nutrition
is delivered by a fertilizer injection system that releases controlled doses of fertilizer into the irrigation system (fertigation). Management of fertigation systems and rates of delivery requires
specialist knowledge, as it is more complex than fertilizing soil or growing media. Hydroponic systems require continual monitoring of pH, water hardness and total dissolved solids (TDS),
and adjustment of these parameters where necessary.

IRRIGATION
The irrigation system is designed to minimize water consumption. It consists of an automation-unit with equipment for control of nutrient injection and irrigation cycles. When a surface has
a variation of sun exposures, the irrigation is divided into segments in order to program it specifically for each part. Within the multi-layered felt surface a drip-tube is integrated. Water
consumption varies with heat and sun exposure, but compared to normal green spaces or a lawn, the consumption is normally lower.
It averages between 2-5 l/m2/day.
For hydroponic green wall systems, the fertigation system may apply 0.5-20 litres of irrigation solution per square metre perday. Internal green wall requirements are at the lower end of this
range, and external green walls at the higher end. Irrigation cycles typically last a few minutes and will be required several times a day. Keeping irrigation volumes low minimises waste and
reduces run-off. Irrigation run-off may be captured in a tank at the base of the wall and recycled back through the green wall system. Green walls that use a high quality, water-retentive
growing medium, and are not in an exposed or particularly hot location, may thrive on a weekly watering regime. In most simple, soil-based systems, including DIY systems, controlled
release fertilizer is mixed in with the growing medium, rather than using a fertigation system. Irrigation must be available as soon as the plants are installed in the wall system. The irrigation
system requires a water meter to monitor irrigation volume, and a pressure gauge to monitor the even application of water. The need for ongoing regular irrigation and the expectation that
water will be used sustainably means that stored (harvested or recycled) water should be used whenever possible, so a pump is necessary
DESIGN PROCESS
Each vertical garden is given a unique design and selection of species. The composition of plants takes in consideration the specific environment
where it will be built, such as the local- and micro climate, sun exposure and the surrounding context. The aim is to create a one of a kind and site-
specific garden that stands beautiful through all the seasons of the year.
A well executed design is also a way to minimize the future maintenance demand of the garden. A plant's growth habit, size and behavior on a vertical
surface is important knowledge for making the right combination of species, in order to keep the competition between plants at a healthy level.
Choosing the right plant for the right place makes sense for any garden, but maybe even more so in a vertical garden..
A vertical garden can be installed in almost any location and as a living material, the potential of integrating plants in our urban environments is
interesting. Places never thought of as possible could be inhabited by plants, like subway stations or other intensely frequented places where horizontal
space is difficult to spare.
LIGHT
Direct sunlight can deliver over 100.000 lux whereas the average light level in an office is around 300-500 lux. Even if the least light demanding
species are used, artificial light is normally necessary indoor. A few species will stay fine at 900 lux, but a slightly increased level at some parts of the
surface will broaden the variation of species that can be used. An artificially illuminated surface has shifting light levels, due to the fact that light
reduces with the square of the distance from the light source. Some areas might have 3.000 lux and others 900 lux. The plant design is made with this
in mind, taking advantage of the higher levels for more demanding and interesting species.

GENERAL CONSIDERATIONS
• Watering: Appropriate time
• Careful selection for wind prone areas (Succulent and hardy plants)
• Removing the dried leaves
• Keeping the structure clean
• Disposing the water from drainage system
• Pruning if necessary
• Timely application of fertilizers
MERITS OF VERTICAL GARDENING
1. Space-Saving:
One of the primary advantages of vertical gardening is its space-saving nature. With vertical gardening, you can grow plants in a limited amount of space, such as balconies, small yards,
and even indoors. This makes it ideal for those who live in urban areas or have limited outdoor space.
2. Improved Air Quality:
Vertical gardens can help improve the air quality in your home or office. Plants naturally absorb carbon dioxide and release oxygen, which can help purify the air and create a more
comfortable environment.
3. Increased Yield:
Vertical gardens can often yield more produce per square foot than traditional gardens. This is because the plants are grown closer together and can receive more sunlight, water, and
nutrients.
4. Reduced Maintenance:
Vertical gardens are typically easier to maintain than traditional gardens. Since the plants are grown vertically, they require less bending and stooping, making them ideal for those with
physical limitations.
5. Aesthetically Pleasing:
Vertical gardens can be visually stunning and can serve as a focal point in any space. They can be designed in a variety of ways, from sleek and modern to rustic and whimsical.
DEMERITS OF VERTICAL GARDENING
1. Limited Plant Selection:
Vertical gardens may not be suitable for all types of plants. Some plants, such as root vegetables, require deep soil and may not grow well in a vertical garden. It's important to research
which plants are suitable for vertical gardening before beginning your project.
2. Watering Challenges:
Watering a vertical garden can be challenging, as water can easily run off or not reach all of the plants evenly. A drip irrigation system or self-watering containers can help mitigate this
issue.
3. Cost:
Vertical gardening can be more expensive than traditional gardening, as it often requires specialized containers, support structures, and irrigation systems.
4. Maintenance Challenges:
While vertical gardens are typically easier to maintain than traditional gardens, they can still require some maintenance. Plants may need to be pruned, fertilized, and monitored for pests and
disease.
5. Space Limitations:
While vertical gardening can save space, it also has its limitations. If you have a small balcony or limited wall space, you may not be able to grow as many plants as you would like.

DESIGN CONSIDERATIONS
The size of the roof: The size of the roof will determine the size of the garden. A large roof will allow for a more extensive garden, while a small roof will limit the size of the garden.
The weight of the garden: The weight of the garden is important to consider, as it will affect the load-bearing capacity of the roof. A heavy garden could put too much stress on the roof and
cause it to collapse.
The type of roof: The type of roof will also affect the design of the garden. A flat roof will be easier to garden on than a sloping roof.
The exposure to the sun: The exposure to the sun will also affect the design of the garden. A garden that is exposed to the sun all day will need to be planted with plants that can tolerate
heat and sun.
The availability of water: The availability of water is important to consider, as gardens need to be watered regularly. If there is no easy access to water, then the garden will need to be
designed in a way that minimizes the amount of water needed.
The budget: The budget will also affect the design of the garden. A large budget will allow for the use of more expensive materials and plants, while a small budget will limit the choices.

CONCLUSION
The dissertation on "Maximising Green Spaces in a Building Complex through Alternative Landscape Design Elements" with respect to roof gardens and vertical gardens has explored the
potential of these alternative landscape design elements to enhance the sustainability, aesthetics, and well-being of building complexes. Through an in-depth literature review, it was
established that roof gardens and vertical gardens offer numerous benefits, including the promotion of biodiversity, mitigation of urban heat island effect, improvement of air quality, storm
water management, energy efficiency, and the creation of green spaces in urban environments. These alternative landscape design elements have the potential to transform underutilized
spaces into thriving ecosystems, enhancing the overall liability and sustainability of building complexes.
The objectives of the study were successfully addressed through the development of a methodology that included site analysis, design considerations, plant selection, structural evaluation,
and maintenance strategies. By implementing a comprehensive approach, the study has demonstrated the feasibility and practicality of incorporating roof gardens and vertical gardens within
a building complex.
The scope of the research has covered various aspects, including design considerations, environmental benefits, social and economic impacts, and challenges associated with the
implementation and maintenance of roof gardens and vertical gardens. Case studies and best practices have been examined, providing valuable insights into successful projects and
highlighting the potential for innovation in this field. While the research has shown the immense potential of roof gardens and vertical gardens, it is important to acknowledge the limitations
of this study. Factors such as structural constraints, high initial costs, limited plant selection, maintenance requirements, and regulatory constraints may pose challenges to the widespread
adoption of these alternative landscape design elements. Further research and collaboration between architects, landscape designers, engineers, and policymakers are necessary to address
these limitations and overcome barriers to implementation.
In conclusion, the dissertation has highlighted the significance of maximizing green spaces in building complexes through alternative landscape design elements, specifically roof gardens
and vertical gardens. The findings of this study contribute to the growing body of knowledge on sustainable urban design and provide practical insights for architects, urban planners, and
stakeholders involved in creating greener and more sustainable built environments. By embracing these alternative landscape design elements, building complexes can embrace a
harmonious coexistence between nature and architecture, fostering a healthier and more sustainable future for urban communities.
