Here in Bainara, in the first phase, we intend to build two single story houses covering 842 square feet each.
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 which are 13 inches in height. This is going to be a load bearing structure and hence it’s important that we use same sized bottles in order to maintain uniformity and proper load distribution throughout the wall.
Lime mortar and lime plaster has been chosen considering its water-resistant property and for being economic compared to cement. A 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 few decades back until gradually, cement turned out to be the people’s choice.
The roof will be of corrugated tin, resting flat on wooden truss made from Eucalyptus tree. The tin sheet will be firmly secured with the wooden 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.
