Once the outer shell is complete, the floors are fitted to the steel frame using fibre-cement or OSB boards, which can be finished with tiles, timber-flooring or carpeting. Next, the inner walls are attached to the inner frame using dry-walling such as gypsum or fibre-cement board. Gypsum’s fire-rating complies with regulations.

Insulation material is then inserted in between the frame and both the outer and inner boards to provide for exceptional thermal and acoustic insulation vs. brick-and-mortar or concrete and glass. Fittings and fixtures for plumbing and power are fitted through pipes drilled into the walls and the interior can be decorated in any way possible.

And that in a “light steel frame” shell, is it.
