Every building has its own idiosyncratic constraints of context, site, program, budget, and vocabulary. The challenge is to successfully resolve them into a gracefully crafted architectural composition. Our role as designers is to ensure that each building has its own personality and responds appropriately to its urban context. This is what we do best.

A number of these projects have been nominated for and received Urban Design and Architectural Design awards. Mr. Kazerouni has been a guest lecturer on the subject of architecture and mixed-use design at universities, conferences and various panels.
