7.What is the cost of Natural building?

        There are two factors mainly affecting the cost of natural building. Labour and material. If you get your materials in the site itself, cost will be coming down. Few factors which affecting cost are,

        New doors & window vs Reclaimed doors & window

        Working with 3 master Mason vs You & your friends working with one Mason

        We have attained the cost of the natural building about Rs. 700/- to Rs. 1400/- per square feet.

We are currently working on ‘Cost of building’ in detail. It will be published soon through our publications.
