HOUSESHOUSE IS A BUILDING THAT FORM AS A HOMES FOR HUMANS AND OTHER

CREATURE.# WIKIPEDIA

LOW COST HOUSELOW COST HOUSE REFERS TO THE COST EFFECTIVE , ECO-FRIENDLY FOR

LOWER AND MIDDLE CLASS PEOPLE.

INTRODUCTION

• Low cost houses can considered affordable to low income people.

• Adequate shelter to the people is the pressing topic to the developing country.

• India have a shortage 17.6 million houses.

THAT MAKE TO PLAN FOR LOW COST HOUSING

FACTOR EFF THE COST OF HOUSE COST OF BUILDING:BUILDING CONSTRUCTIO COST CAN BE DIVIDED IN TWO GROUPS I,E CONSTRUCTION COST AND LABOUR COST.

SIZE: SMALLER THE PROJECT IN TERM OF SCOPE AND SIZE MORE WILL THE COST PER SQUAR FEET

TYPE: DIFFERENT TYPE OF PROJECT HAVE DIFF COMPLEXITY AND DETAILS.

MATERIALS: USE OF LOCAL MATERIALS

NOW THE QUESTION ARISES ,HOW TO MAKE THE

HOUSE AS LOW COST

HOW???

•RECYCLING•LOGICAL PLANNING•PREFABRICATION•MATERIAL USAGE•OTHER TECHNIQUES

GENERAL METHODS ADOPTED ARE

RECYCLING

VARIOUS RECYCLED MATERIALS USED ARE:

•Wood. •Glass.•Rubber.•Plastics.•Steel cans. etc

LOGICAL PLANNING

•PROPER PLANNING•EXACT DIMENSIONS•BEST MATERIALS WITH IN BUDGET•SPACE CONSIDERATION •USE OF LOCAL MATERILAS

PREFEBRICATIONR.C.C PLANKS AND JOIST PRECAST CONCRETE L-SECTION

BRICK PANEL PRECAST HOLLOW SLAB

COST EFFECTIVE

TECHNIQUES

FOUNDATION:Arch foundation:

• It reduces the construction cost up 40%• It can be used in the sandy soil.

OTHER:• RANDOM RUBBLE MASONRY

WITH CEMENT OR MUD MORTAR PLACE ON THE SANDY

BED.•UNDER RIMMED PILES ARE

USED IN CASE OF BLACK COTTON SOIL.

WALLS

• Rat Trap Bond•It is type of brick wall masonry in which the brick are laid at the edge.•It give the internal cavity which can be bridge by rowlock.•It gives thermal comfort .•It reduces the cost up 30-40%

•It reduces the number of bricks.•In turn it reduces the cost of material. •Provide pleasant effect to the building.

BRICK JALIS

OTHER TECHNOLOGIES ARE

• Soil cement wall technology.• Concrete block walling.• Fly ash sand lime gypsum brick.• Black cotton and inferior soil bricks stabilized

by fly ash• Compressed mud block masonry.

ROOF:

Ferro cement channel roofing• FERRO CEMENT IS A COMPOSITE

MATERIALS OF CEMENT AND SAND APPLIED OVER AN WOVEN OR MESH OF STEEL.

• FERRO CEMENT CHANNELS ARE USED FOR ROOFING.

• LESS LABOUR REQUIRED• REDUCED 30% THAN RCC COST.• LEAD LOAD IS LOW.

FILLER SLAB-TECHNIQUE

The filler slab is based on the principle that for roofs which are simply supported, the upper part of the slab is subjected to compressive forces and the lower part of the slab experience tensile forces. Concrete is very good in withstanding compressive forces and steel bears the load due to tensile forces. Thus the lower tensile region of the slab does not need any concrete except for holding the steel reinforcements together.

Laurie Baker :• Born in 2 March 1917.• Was an award-winning British-born Indian architect.• Renowned for his initiatives in cost-effective energy-efficient architecture.• Designed largely on site.• Built Houses for lower-middle to lower class clients.• Made a name for himself both in sustainable architecture as well as in organic architecture.• Made many concepts related to low cost housing.• Died on 1 April 2007 at the age of 90.

Example : The Hamlet – Laurie Bakers Home..

This is Baker’s home in Trivandrum.

.

CONCLUSION:

• Low cost housing can be achieved by the use of locally available materials.

• Low cost housing can be achieved by the use of recycled materials

• Low cost housing can be achieved by adopting the cost effective techniques.

• Even a poor people can have there own houses.
