Urban Design / Infrastructure


For over 30 years our urban design efforts have been recognized for their well researched, clear and appropriate responses to the goals and requirements of complex planning problems. We do not subscribe to a specific approach or design ideology and innovation is based on a foundation of solid research and precedent.  We look for and find the best and most holistic solution within the problem itself and we validate that solution against solid research and analysis. We explore hidden systems and infrastructure and develop an understanding of patterns of use and what can be called “urban opportunity” to validate our proposals.


Bridge design has grown out of our urban design work. The complexities of this project type and architectural and technical responses required fits well with our integrative design approach.


Our architects and designers work closely with our engineers as equal partners throughout the design process.
