Donald Insall Associates were appointed in 2013 to assist in proposals to redevelop the buildings at 16-26 Park Crescent and 83 Portland Place (Grade I listed), and 77-81 Portland Place (Grade II listed), located in the Harley Street Conservation Area. This project presented a unique challenge which centred on the fact that, contrary to their list descriptions, the buildings were not those built to designs by John Nash in 1812 but instead post-war replicas built in the early 1960s. Provenance notwithstanding however, the terrace remained of very high significance because it preserved the impression of Nash’s original and innovative concept for the Regent’s Park. Donald Insall Associates worked closely with the client, architect and Historic England to develop a scheme to demolish 16-26 Park Crescent West and to build a scholarly replica of the facade of the original Nash terrace in its place, with modern residential accommodation behind and to redevelop the 77-81 Portland Place behind their higher quality replica retained facades. Our Historic Building Report produced in support of the scheme demonstrated that in this very rare case, the complete demolition of the Grade I listed terrace and its replacement with a more scholarly replica would preserve and enhance rather than obliterate its significance.
