Heritage Surveys and Asset Protection

Heritage Surveys and Asset Protection

The protection of heritage assets sits at the heart of our communities.   Ayesa London assesses the condition and advises protection strategies for heritage assets that are vulnerable either from developments (which in cities may include construction above and below ground - such as underground rail, stations and tunnels) or from fire and flood or a result of past alterations and additions over the years.

HS2  - The southern section of the HS2 Crossrail from Euston to West Ruislip Portal traces a route directly through 170 Listed Buildings and 80 Listed Monuments. Ayesa’s Conservation Team has been engaged to undertake the survey work of each and every one of these heritage assets, assessing the tunnelling impacts on those structures that sit with the ‘1mm settlement corridor’.   Our HS2 brief goes beyond identifying structural robustness, it delves into historic features and attributes to recommend protection and mitigation measures that preserve the heritage.

St. Patrick’s Church Soho  - Recently, we provided monitoring and inspection services for the Grade II* listed St Patrick’s Church in Soho Square to identify potential damage caused by the construction of a new tunnel and station at Tottenham Court Road.  Our team also assisted with financial settlement and advised remediation works to restore the church.

When excavation works began at Bank Station and surrounding tunnels to increase the capacity of the Northern Line,  we were appointed to monitor the condition and movement of the Grade I listed St. Mary Abchurch throughout construction.   Following our survey and investigations, we recommended remediation works to ensure the prior condition of the building was retained.   

St. Stephen’s Rosslyn Hill is a remarkable, recently restored Grade I neo-gothic church situated on a steep slope beside the Royal Free Hospital.  Our team was appointed to monitor the potential effects and damage caused by groundworks at the hospital.
