London-based architectural practice, specialising in sustainability, heritage and the home

Sustainability

Whether adapting old housing stock to modern standards or building anew, TJA promote a fabric-first approach, maximising the performance of the building envelope before investing in new MEP equipment. This is about insulation, air-tightness and smart use of thermal mass, solar-gain and natural ventilation. Other sustainability considerations include lighting, drainage, biodiversity and running costs, but the most valuable starting point is to explore the potential in what has already been built.

Heritage

We are custodians of our built past. Reciprocally the built past must also be custodian of our present. TJA understand this relationship and enjoy the research that underpins designing within sites of historic significance. It requires care and confidence and the result should be a celebration of both old and new.

The Home 

TJA began with projects for people adapting to new ways of working and being at home in 2020. The architecture of domestic life remains the focus of the practice, working across a range of budgets and typologies - room, flat, maisonette, townhouse, summerhouse, garden, campus and even a Dutch barge. Home means different things to different people and that’s what interests TJA.
