Building Systems

How construction methods, structures and technical interfaces shape architecture — assemblies, details and systems explained for working designers.

Building systems influence cost, programme, carbon, tolerances, transport and the freedom to change a project later. Labels such as prefab, modular or mass timber are starting points, not automatic guarantees of speed or sustainability.

This topic compares systems through the decisions that matter before procurement: geometry, interfaces, local capability, certification, logistics and whole-life performance. Claims are tied to sources and their limitations.
