Single Storey Extension to a Listed Building
Technical design for an extension to a Grade II listed building at 72 Heath Street, Hampstead, with an existing basement and restricted site access.
Project overview
The Project
At 72 Heath Street, NW3, AC Design Solution was appointed for the Building Regulations drawings, structural engineering and Party Wall surveying for a single-storey extension to a Grade II listed building.
The existing basement and tight urban plot made the junction with the retained building and the method of getting structural members onto site particularly important. The scheme used spliced timber-frame construction to work within the access constraints.

Designing around restricted access
The structural package considered the existing building and basement alongside the new extension. Spliced timber members allowed the frame to be assembled where bringing in full-length elements would be difficult. The structural information was coordinated with the Building Regulations drawings and Party Wall scope.
Consent and delivery
Project Outcome
The appointment brought three technical disciplines together for the same listed-building extension: construction drawings, structural engineering and Party Wall surveying. For another project involving existing flats and an extension in Hampstead, see Akenside Road.
