Structure and construction method.

Abstract

A core wall structure is assembled by attaching together elements of lightweight thermal insulation material (16) and elements of minerai board (20), positioned between them to serve as webs (20) at spaced intervals. Opposing edges (22) of the webs (20) are exposed on outer surfaces (26,28) of the core wall structure, with recesses (24) around them. Skins (18) of cementbased plaster are applied to the outer surfaces (26,28) to caver the core wall structure at least in part and to embed the exposed edges (22) of the webs (20) at least in part in the cement-based plaster.
