Here in Bainara, we intend to build two single-story houses covering 842 square feet each in the first phase.
A stepped foundation 3 feet deep will stand as the base of a 4 feet plinth holding a 10 feet high wall. The wall thickness will be finished at 16 inches considering 1.5-inch plaster on both sides using 1-litre water bottles, 13 inches in height. This is going to be a load-bearing structure. Hence, we must use the same sized bottles to maintain uniformity and proper load distribution throughout the wall.
Lime mortar and lime plaster have been chosen considering their water-resistant property and economical compared to cement. Fine red brick dust, commonly known as Surkhi or a black coal powder known as Ghyash, will be used instead of sand. Mixed in the ratio of 1:3 (Lime: Surkhi/Ghyash), this is a time-tested age-old recipe common to this region in vogue even a few decades back until gradually, cement turned out to be the people’s choice.
The roof will be of corrugated tin, resting flat on a wooden truss made from a Eucalyptus tree. The tin sheet will be firmly secured with the rigid members with nuts and bolts covered with an added top layer of lime mortar gently beaten to settle down to become a water-resistant and good thermal insulator. A flat roof will also mean that it would be the least hazardous when exposed to high wind load.
