Karen Horncastle is a Chartered Architect and a founding Director of horncastle:thomas, architects and designers.
In her previous role at APA architects she was design and project architect for the Department of Environment, Food and Agriculture headquarters at St John’s.
The DEFA HQ was the first, and remains the only, building on the Island to achieve an “Excellent” rating under the energy and sustainability benchmark rating BREEAM. In 2012, it was the overall winner at the Green Apple Awards.
Karen's involvement in this groundbreaking (for the Isle of Man) building has prompted a continuing interest in sustainable design which forms part of the ethos behind the work of her new practice.
