Inexpensive to build
Save money while also maintaining building
Not sacrificing the strength, performance and life
of the structure
Takes less time in building in comparison to the
Use of resources while not harming the
Final result should be affordable for most people
Why do we need low cost
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
Different building techniques
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
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
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
At the site, the pieces are connected to the
Since materials aren't assembled on-site,
owners save money on construction time,
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
It is less expensive for contractors
Techniques to reduce cost from
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
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.
Construction technique adopted
The foundation cost comes to about 10 to 15% of the
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.
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
By adopting rat-trap bond method one can
create aesthetically pleasing wall surface
and plastering can be avoided.
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
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
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.
Normally 5" thick R.C.C. slabs is used for roofing of
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%.
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.

This is Baker’s home in Trivandrum built on a plot of land
along the slope of a rocky hill, with limited access to water.
Baker’s genius has created a wonderful home for his family.
Material used from unconventional sources.
Electricity wiring is not concealed.
According to Baker, fans and lamps can be avoided as in
India there is sunlight all round the year, which also means
that if water is stored in the southern part of the house, hot
water can be made available.

IIT Madras-The 6.5 lakh home
The researchers from the civil engineering department of IIT
Madras have developed a method for low cost housing.
This is to build rapid, cost-effective mass housing using glass
fiber reinforced gypsum (GFRG) panels. Gypsum is a waste
by product of the fertilizer industry & an environmental hazard
This method of construction is not only less expensive(cost
2/3rd), but also less time consuming as the 'GFRG demo
building' was constructed by the IIT team in just a month and
is even ecofriendly.
Since 2003, the IIT-Madras research team had conducted
How its made ?
These panels, originally developed by RBS Australia, were
intended as wall panels ('Rapidwall') suitable for rapid erection of
walls in buildings to carry gravity loads.
The panels are made of calcined gypsum plaster, combined with
special additives and glass fibres, to produce GFRG panels - 12m
long, 3m high and 124mm thick (with hollow cavities).
The IITM research group extended the application of this product
for the entire building system - including floors, roofs, and
staircases, thus significantly reducing the consumption of
Reinforced Cement Concrete (RCC).
The team also collaborated in the indigenous development of an
excellent water-proofing material, which is essential for prolonged
durability of the GFRG panels, especially in the case of roofs and
The panels are prefabricated and cut to desired sizes
based on room dimensions with openings for doors and
windows, thus making rapid construction possible.
Filling the cavities with concrete increases the vertical
load-carrying capacity almost tenfold, and inserting
vertical steel bars in these cavities, contributes to their
Advantages over conventional
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
Lower building weight (panels weigh only 43 kg/m2),
contributing to savings in foundation and reduction in
design for earthquake forces, particularly in multi-
Buildings up to 8-10 storeys can be designed using
this load-bearing system, without the need for beams
Settling the roof
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
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
