Project Overview
This is a multiple award winning project. Originally constructed in 1968 and consisting of three 11-storey residential blocks. The flats provide 107 affordable homes for Portsmouth City Council.
The retrofit and refurbishment of Wilmcote House has extended extend its life for a minimum of 30 years, providing both a sustainable Passivhaus approach for the estate’s regeneration, as well as contributing to the Somerstown area-wide regeneration.
The scheme includes remediation of the external structure, comprising new insulated over-cladding, triple glazing and extension of living spaces and enclosure of balconies.
The regeneration took place with the residents in occupation, which was facilitated by an innovative structural solution, utilising an exterior steel structure to support the new cladding envelope. The fixing of the steel frame required special connection details, to reduce thermal bridging and satisfy the Passivhaus requirements.
The Challenge
Residents were in occupation of Wilmcote House and decant procedures were set to be highly disruptive and costly.
Our Solution
The regeneration took place with the residents in occupation, which was facilitated by an innovative structural solution, utilising an exterior steel structure to support the new cladding envelope. Keeping residents in their homes avoided expensive and complicated decant procedures.
