RAAC has been in the headlines for the past couple of years, primarily in schools and public buildings where the material has degraded beyond its design life. Reinforced Autoclaved Aerated Concrete: the structural problem it presents is serious.

Church House, the community building supporting Holy Trinity Brompton in West London, is one of the buildings that contains it. CGA has commenced works on a programme that combines RAAC remediation with structural strengthening, internal reconfiguration and a full mechanical and electrical overhaul.
The building does a lot. It provides accommodation, offices, meeting spaces and catering facilities for HTB, an Anglican church with a large congregation and significant international reach through the Alpha course. Church House is not peripheral. It is central to how the community functions.
A building like this is never quiet. Works have to be phased around a programme of continuous occupation. Getting that right is as important as the technical delivery.
RAAC remediation is the most technically demanding element: structural support work carried out within a building that never stops. Works are underway.
