Estate-style houses are typically built with brick veneer walls, a concrete slab on the ground, aluminium windows and a metal roof. Concrete slabs are more efficient that uninsulated timber floors, and they provide excellent thermal mass when paired with areas of north facing glass. The sun will heat up the concrete or tiles in winter and release the heat during the night.
