Sun baked brick wall panels construction easily done by the unskilled local communities from both neighbouring countries divided for over a century by the imposed boarder to reunite again by building a Market place in the no-man’s land.

Sun-baked earth brick wall panel It is a non-load bearing wall To be built within the reinforced concrete walls and beam that will carry the dead load of the building
