The most sustainable building is often one that already exists. We take a holistic approach to renovation, focusing on adaptability, accessibility and long-term performance to ensure improvements to energy efficiency and the building fabric are effective and lasting.

HTA has a strong history of reimagining existing buildings, from listed conversions to the transformation of former non-residential spaces. In Altered Estates 2, we proposed a method to assess whether well-located homes could be retained and upgraded.

Recent examples include the renewal of studio flats at Sutton Estate, Nevern Square and Chelsea Court, turning 100-year-old housing into homes fit for the next century. At Wensley Road, we re-enveloped three post-war towers, introduced ground-level entrances, and set them in a newly designed biodiverse landscape.
