Concrete floors offer a hard-wearing (virtually indestructible) surface and can also help to moderate temperature inside the home. The range and variety of concrete floors available is mind-boggling. You can expose the aggregate, polish, add oxide to colour the concrete or a combination of all of these options. The best designs utilise the thermal mass of concrete to absorb the sun's heat to keep the home warmer in winter. Pair concrete floors with clerestory windows facing the sun to achieve this win-win situation.
