We are an architecture and design firm based in New York City. A team of seasoned professionals, we are grounded in the fundamentals of the field yet intuitive enough to improvise. We establish a logical process and engage in a continuous dialogue with our clients, seeking emotional as well as practical solutions that are both site-specific and stirring in their counterplay of form, texture, light and space. By turns bold and subtle, we are guided by a modernist ethos, a belief in the elegance of clean lines, the aura of free-flowing spaces.
We bring these principles and practices to each of our projects—urban and rural; corporate, commercial and residential—creating spaces that inspire human connection and fulfillment.

His clients have included Loews Hotels, Universal Orlando, SLS Hotels, Hyatt, Daniel Boulud, Louis Vuitton, SL Green, Fisher Brothers Development and SOHO China.
