In the US the overwhelming amount of houses are constructed of light frame timber (2×4 or 2×6) then surfaced with either a cementous product like stucco or wood siding of some form. Larger homes and multi-family buildings used to be constructed of brick but modern larger homes and multi-families tend towards wood framing. Multi-families become concrete and steel frame once they go above five stories. Individual houses can be made of heavy timber light, heavy steel, concrete masonry or more exotic materials, but these tend to make up far less than 1% of the constructed houses.
