  • 2. + Low cost housing refers to houses that areinexpensive to build. IT doesnt mean that thehouses will be inexpensive to live in.+ Less the house costs to build, the more energy ittends to waste, leading to much higher utility bills.+ The goal of low-cost housing is to save moneywhile also maintaining buildings quality.+ Following Properties Reduces CostConstruction:•Locally available materials .•Improved skills and technology.•Without sacrificing the strength, performance andlife of the structure.+ Low cost housing is done by propermanagement of resources as well as by utilizing
  • 3. 1. Recycling2. Extensive Planning3. Modular Planning4. Infilling
  • 4. •Recycled materials adapted for low-cost housing include wood and rubber.•Are previously been used.•Reprocessed into materials that are used in building walls and other parts ofa house.•Recycled glass and metal are also used on occasion.•These recycled materials are often less expensive than using fully naturalproducts.
  • 5. •In extensive planning, the more planninggoes into a house, the less the actualconstruction will cost.• Contractors should plan out exactdimensions.•Contractors should gather facts.•Contractors should look for the bestmaterials at the cheapest prices so they canorder exactly what they need.This saves money that would otherwise bewasted on unnecessary supplies andcleanup caused by littered materials.• Most houses are built as quickly aspossible without this detailed planning
  • 6. + Modular building is a type of constructionwhere pieces of the home or typically wholerooms or major parts of rooms ,are built off-site in large factories.+ This process allows the pieces to be builtefficiently and exactly according to buildingstandards.+ At the site, the pieces are connected tothe house.+ Owners can typically choose how manymodular rooms they want.+ Since materials arent assembled on-site, owners save money on constructiontime, including the time it would take to clearaway the construction debris.+ Owners also save money on constructionfinancing interest if theyre using aconstruction loan.
  • 7. • Infilling is the practice of going backthrough residential areas and buildingin areas that had previously been leftempty.• Now its possible to build on becauseof resolved environmentalconcerns, space issues or otherproblems that have since beenremedied.• Infilling makes better use of existingspace.• It is less expensive for contractorsoverall
  • 8. 1) Reduce plinth area by using thinner wallconcept.2) Use locally available material in aninnovative form like soil cement blocks inplace of burnt brick.3) Use energy efficiency materials whichconsumes less energy like concrete block inplace of burnt brick.4) Use environmentally friendly materialswhich are substitute for conventional buildingcomponents like use R.C.C.

  • 9. 1. Foundatio n2. Wall3. Lintel4. Roof
  • 10. + The foundation cost comes to about 10 to 15%of the total building+It is adopted for single or double storey building.+ It is recommended to adopt a foundation depthof 2 ft.(0.6m) for normal soil like gravely soil, redsoils etc.+ We should use the uncoursed rubble masonrywith the bond stones and good packing.+To avoid cracks formation in foundation themasonry shall be thoroughly packed with cementmortar of 1:8 boulders and bond stones at regularintervals.+ Suggested to adopt arch foundation in ordinarysoil for effecting reduction in construction cost upto 40%.+ This kind of foundation will help in bridging theloose pockets of soil which occurs along thefoundation.
  • 11. •Wall thickness of 6 to 9″ is recommended foradoption in the construction of walls all-round thebuilding and 41/2 ” for inside walls.•It is suggested to use burnt bricks which areimmersed in water for 24 hours and then shall beused for the walls.• Making use of Rat – trap bond wall & Concreteblock wall.* It is a cavity wall construction and leads toreduction in the quantity of bricks required formasonry work.* By adopting this method of bonding of brickmasonry compared to traditional English orFlemish bond masonry, it is possible to reduce inthe material cost of bricks by 25% and about 10to15% in the masonry cost. * By adopting rat-trapbond method one can create aesthetically pleasing
  • 12. •In view of high energy consumption byburnt brick it is suggested to use concreteblock which consumes about only 1/3 ofthe energy of the burnt bricks in itsproduction.•By using concrete block masonry the wallthickness can be reduced from 20 cms to15 Cms.* Concrete block masonry saves mortarconsumption, speedy construction of wallresulting in higher output oflabour, plastering can be avoided therebyan overall saving of 10 to 25% can be
  • 13.  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.
  • 14.  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.

  • 16. • Born in 2 March 1917.• Was an award-winning British-born Indianarchitect.• Renowned for his initiatives in cost-effective energy-efficient architecture.• He never maintained a regular office.• Often sketched on waste paper.• Designed largely on site.• Built Houses for lower-middle to lowerclass clients.• Made a name for himself bothin sustainable architecture as well asin organic architecture.• Made many concepts related to low costhousing.• Died on 1 April 2007 at the age of 90.
  • 17. •This is Baker’s home in Trivandrum. •Material used from unconventional sources.• Unique house built on a plot of landalong the slope of a rocky hill, with • Family eats in kitchen.limited access to water. • Electricity wiring is not•Baker’s genius has created a concealedwonderful home for his family.
  • 18. • Built In Furniture For The Hamlet.•Made Use of BRICK JALLIS.• Effective way to minimize your electricitybills.
  • 19. BUILDING MATERIAL:+ RECYCLED Wood from traditionaldemolished building.
  • 20. + All materials are used in their natural form, exposed brickwork, mortar, concrete shows the truthfulness of materials.+ Baker’s loves to material in their natural form.
  • 21. Surface treatment was doneby Using Waste Materials
  • 22. QUALITY OFSPACES
  • 23. • According to Baker, fans and lamps can be avoided through appropriate planning.•In india there is sunlight all round the year, which means that if water is stored in thesouthern part of the house, hot water can be made available.•Garbage can be recycled.•Only a person like baker has the courage for this, because his motive is not just tomake money
