Walls and cladding

Houses built in the 1940s-60s typically used timber (native or exotic) for framing, and weatherboard, brick, asbestos-cement or stucco cladding.

In any renovation, you’ll need to consider insulation, and may have to deal with issues such as undersized framing and inadequate bracing.
