Holding historic facades while everything behind them changes - and restoring the envelope itself.
Facade work splits into two related disciplines. Retention keeps a facade standing - on a temporary steel frame - while the building behind it is demolished and rebuilt, the classic move where planning requires the street frontage to survive. Restoration repairs the envelope itself: stone and brick cleaning and repair, repointing, terracotta and faience replacement, cladding remediation and the modern recladding programmes driven by fire-safety regulation.

Facade Retention & Restoration in depth
About Facade Retention & Restoration
Both live on survey quality. A retention scheme is a temporary works design carrying wind load on a structure that was never meant to stand alone; a restoration contract on a listed elevation is negotiated stone by stone with a conservation officer. Neither forgives assumptions about what the wall is actually made of.
