Challoner House has been Highly Commended at the Architects’ Journal Retrofit and Reuse Awards, in the Adaptive Reuse into Office category!
Some generous words from the AJ:
“Challoner House exemplifies a thoughtful and sensitive adaptive reuse, transforming a modest historic building in Clerkenwell into a quietly beautiful, light-filled office space. Its ‘fabric-first’ approach prioritises retention and reuse of existing materials – exposed brick, steel and glass – honouring the building’s history while achieving spatial clarity and rich character.
Clever interventions, such as combining two low-ceilinged floors into a generous double-height auditorium, optimise the plan’s flow and light. Extensive use of breathable, low-carbon materials underscores the commitment to sustainability, earning the project a deserved honourable mention in this category.”
