JHA is a design-led practice based in London & working within the UK

JHA is a registered architectural practice working on numerous projects in London and the UK. The Studio is based in London and has gained a glowing reputation for high-quality design and execution, specialising in residential projects.
JHA has experience within the commercial and public sectors, working on projects within both conservation areas and listed buildings
As a design-led and research-orientated practice, inspiration is drawn from the context both wider and more immediate to create a contextual design and considered approach to each brief.
The studio works with a variety of scales and has an interest in the process of building from the concept design through to construction and completion, ensuring quality and prolonged building health and lifespan.
JHA has a particular interest in materiality, blending new and historic elements in a contemporary but sympathetic way through architectural gestures. The smaller scale elements such as lighting, ironmongery, and furniture are considered with equal care and attention.

Sustainability
Sustainable design is fundamental to the process at JHA and ingrained in our work philosophy. The construction sector plays a substantial role in global carbon emissions. We've chosen to confront this stark reality with enthusiasm and hope, placing a primary focus on architectural designs that acknowledge the evolving climate.
