Insulated cavity walls, trussed rafter roofs, uPVC windows and, increasingly, timber-frame construction behind a brick outer skin. Most carry a warranty from new.
What we usually find. Generally sound, with issues tending to be maintenance rather than construction: sealed-unit windows losing their seal, render cracking, and condensation where ventilation has not kept pace with later draught-proofing.
Worth knowing. Timber frame behaves differently from masonry and should not be altered as though it were solid. Removing or breaching an internal wall without advice can be a real problem.

Modern insulated construction to current Building Regulations, normally with a ten-year structural warranty, high levels of airtightness and mechanical ventilation in the newest homes.
What we usually find. Structural defects are uncommon; the recurring themes are condensation and interstitial damp where airtight construction meets ventilation that is switched off or never commissioned, along with workmanship snags in newer developments.
Worth knowing. On flats and any property with external wall insulation or cladding, establish the position on fire safety documentation early, as it can hold up a sale regardless of the building’s condition.
