Keystone Architecture and Design are a small, progressive architecture company with our head office in Worcester, and our team spread across Cambridge, Cardiff and Rome. We are a team f architect with a Certified Passive House Designer in our office. We are sustainability focussed, and are able to deliver high performance buildings that suit our clients’ needs, whether that’s an eco-retrofit on a historic building using natural building materials, a high-tech new-build maximising the use of renewable technologies, or anything in between. We take a client-centred approach to ensure that our design is tailored to the project specific context and requirements so we can achieve the aspirations set out at the start.
