Newquay House was a 1930s walk-up estate in Kennington, originally designed by Louis de Soissons for the Duchy of Cornwall. By the 1980s, the building was deteriorating, flats were cold, cramped, and poorly suited to modern family life. Working with the RIBA Pilot Group and tenants, HTA carried out a feasibility study that laid the groundwork for a collaborative transformation of this Grade II listed site. Using the successful model developed at Lea View House, we set up a project base on site and formed a tenants’ panel to explore needs, aspirations, and priorities. Consultation revealed the value of the estate’s multi-generational community and the desire for modern, comfortable homes. The design introduced new front doors on the street, enclosed and secure courtyards, and reconfigured layouts to create family maisonettes, homes for older residents, and a shared community room at the heart of the block.
