The Practice has built and is building a great diversity of projects. Our reputation for conservation work, individual houses and residential schemes has broadened into major office , retail and mixed use projects. We are currently also engaged in designing hotels, schools, a play centre and a performing arts venue. History tells us that good architecture results from the dynamic interaction between client and architect, and focusing on this remains central to our work.
