3. Key Features
 Inexpensive to build
 Save money while also maintaining building
quality
 Not sacrificing the strength, performance and life
of the structure
 Takes less time in building in comparison to the
conventional ones
 Use of resources while not harming the
environment
 Final result should be affordable for most people

4. Why do we need low cost
houses?
 Growing population day by day
 Affordable housing for BPL people
 We need a solution that is fast
 Easy to build
 Fulfills the needs of conventional houses
 Our country aims that in our near future each and
every individual has his/her shelter for his family
and to fulfill this need we definitely need some
immediate plans

5. Different building techniques
are:
 Recycling
 Extensive planning
 Modular planning
 Infilling

6. Recycling
 Recycled materials adapted for low-
cost housing include wood and
rubber that are previously been used.
 Reprocessed into materials that are
used in building walls and other parts
of a house.
 Recycled glass and metal are also
used on occasion.
 These recycled materials are often
less expensive than using fully
natural products.

7. Extensive planning
 In extensive planning, the more planning
goes into a house, the less the actual
construction will cost.
 Contractors should plan out exact
dimensions and should gather facts.
 Contractors should look for the best
materials at the cheapest prices so they can
order exactly what they need.
 This saves money that would otherwise be
wasted on unnecessary supplies and
cleanup caused by littered materials.
 Most houses are built as quickly as
possible without this detailed planning
beforehand.

8. Modular planning
 Modular building is a type of construction
where pieces of the home or typically whole
rooms or major parts of rooms ,are built off-
site in large factories.
 This process allows the pieces to be built
efficiently and exactly according to building
standards.
 At the site, the pieces are connected to the
house.
 Since materials aren't assembled on-site,
owners save money on construction time,

9. Infilling
 Infilling is the practice of going back
through residential areas and
building in areas that had previously
been left empty.
 Now its possible to build on because
of resolved environmental concerns,
space issues or other problems that
have since been remedied.
 Infilling makes better use of existing
space.
 It is less expensive for contractors
overall

10. Techniques to reduce cost from
area
 Reduce plinth area by using thinner wall concept.
 Use locally available material in an innovative form
like soil cement blocks in place of burnt brick.
 Use energy efficiency materials which consumes less
energy like concrete block in place of burnt brick.
 Use environmentally friendly materials which are
substitute for conventional building components like use
R.C.C. Door and window frames in place of wooden
frames.
 Preplan every component of a house and rationalize the
design procedure for reducing the size of the
component in the building.
 By planning each and every component of a house the
wastage of materials due to demolition of the
unplanned component of the house can be avoided.

12. Construction technique adopted
 Foundation
 Wall
 Lintel
 Roof

13. Foundation
 The foundation cost comes to about 10 to 15% of the
total building
 Suggested to adopt arch foundation in ordinary soil for
effecting reduction in construction cost up to 40%.
 In the case black cotton and other soft soils it is
recommend to use under ream pile foundation which
saves about 20 to 25% in cost over the conventional
method of construction.

14. wall
 Making use of Rat – trap bond wall &
Concrete block wall.
 It is a cavity wall construction and leads to
reduction in the quantity of bricks required
for masonry work.
 By adopting this method of bonding of
brick masonry compared to traditional
English or Flemish bond masonry, it is
possible to reduce in the material cost of
bricks by 25% and about 10to 15% in the
masonry cost.
 By adopting rat-trap bond method one can
create aesthetically pleasing wall surface
and plastering can be avoided.

15. Concrete block walling
 In view of high energy consumption by
burnt brick it is suggested to use
concrete block which consumes
about only 1/3 of the energy of the
burnt bricks in its production.
 By using concrete block masonry the wall
thickness can be reduced from 20 cms to
15 Cms.
 Concrete block masonry saves mortar
consumption, speedy construction of wall
resulting in higher output of labour,
plastering can be avoided thereby an
overall saving of 10 to 25% can be
achieved.

16. Lintel
 The traditional R.C.C. lintels
which are costly can be replaced
by brick arches for small spans
and save construction cost up to
30 to 40% over the traditional
method of construction.
 By adopting arches of different
shapes a good architectural
pleasing appearance can be
given to the external wall
surfaces of the brick masonry.

17. Roof
 Normally 5" thick R.C.C. slabs is used for roofing of
residential buildings.
 By adopting rationally designed construction practices like
filler slab and precast elements the construction cost of
roofing can be reduced by about 20 to 25%.
 Filler slabs
They are normal RCC slabs where bottom half (tension)
concrete portions are replaced by filler materials such as
bricks, tiles, cellular concrete blocks, etc
 These filler materials are so placed as not to compromise
structural strength, result in replacing unwanted and
nonfunctional tension concrete, thus resulting in economy.
 These are safe, sound and provide aesthetically pleasing
pattern ceilings and also need no plaster.

18. •Affordable Housing
Affordable housing
Demand for housing in India is literally going through the
roof. To cater to the increasing demand, Tata BlueScope
Steel supplies affordable housing solution - a Complete
Solution to the customer right from Conceptualization-
Design-Manufacturing- Supply.
Thus, using light guage structure (LGS) along with world
class ZINCALUME® steel and COLORBOND® steel, Tata
BlueScope Steel provides all benefits of a conventional
house in a very short span of time.

19. To counter the various problems, optimum residential
buildings have to be built in huge numbers, not only to
prevent the expansion of slums and chawls, but also for its
eradication.
This solution provides steel houses that can be erected in a
very short span of time and which have all features
equivalent to or better than conventional houses.
These LGS houses have been tested and are in use in
various countries such as the USA, China, Malaysia,
Vietnam, Indonesia, etc. to name a few.
NGOs, Government Agencies, Corporates and Individuals
involved in Rehabilitation/ Relief works can make use of
our affordable housing solutions.
Benefit to society

20. Advantages over conventional
buildings:
High speed of construction
Less built-up area for the same carpet area.
Less embodied energy and carbon footprint:
significant reduction in use of cement, sand, steel
and water; recycling of industrial waste gypsum.
Lower cost of structure: savings in materials; no
plastering.
Lower building weight (panels weigh only 43 kg/m2),
contributing to savings in foundation and reduction in
design for earthquake forces, particularly in multi-
storeyed construction.
Buildings up to 8-10 storeys can be designed using
this load-bearing system, without the need for beams
and columns.

22. Conclusion
 There is a strict need at present in India for
building cheap and affordable houses
 It is the key to nations development ,to provide
proper shelter to its citizens
 The growing population in urban areas have led to
a strict shortage in land, congested traffic and
housing shortfall
 This has also led to the hike in prices which
makes it impossible for common people to have
their own houses
 Thus there is a immediate need for construction of
cheap houses in large scale
