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

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.

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.
