St John’s is a fine Grade I listed church set on the edge of Hampstead. It was completed in 1823.
The PCC of St John’s church were anxious to develop new facilities for their growing congregation, but also to address significant concerns over structural movement that had been occurring since its original construction. A programme of repairs was carried out in the 1960s but this proved unsuccessful and the building continued to crack.
CTP were called in to assist MEB Architects in what was to be a major project. We carried out surveys and inspections of ground conditions, foundations and walls to diagnose the settlement and bulging. Foundation work was instigated to arrest the movement and defects were repaired.
CTP developed designs to form a new basement that was constructed below the footprint of the existing ground floor. The work was made the more complex by the presence of significant groundwater.
