Peter Zimmerman Architects, an award winning firm, founded in 1982, is a full service residential design firm. Our firm has produced an extensive portfolio of private residences, barns, guest houses, pool houses, conservation easements, comprehensive property designs, private wineries and equestrian centers across the country. Our design philosophy is deeply rooted in the historic traditions of architecture: classical proportion and scale, the balance of shadow and light and the importance of the sustainable relationship between materials. We strive to design spaces that create a sense of transparency between the interior and exterior environments. All of our designs focus on the seamless integration between the built and natural environment, while remaining faithful to historic roots and responding sensitively to the surrounding cultural context. The unique natural features of each property greatly influence our design response. Architecture needs to respond to the individual characteristics of the site and the clients' personalized requirements in order to create spaces that engage and enrich their lives. The largest gesture down to the smallest element in our designs becomes an expression of the balance and harmony between the compression and expansion of space, the interplay of light and shadow and the rules of scale and proportion. Your house should be as much of a delight in a decade as it was on the day you moved in.


Peter Zimmerman and his team are not only consummate professionals, but incredibly creative and a joy to work with. They understand they are helping you create your home and are able to translate your dreams into reality, in fact take your wildest hopes to a higher level! They intuitively understand that real people live in their drawings and create cozy, comfortable and workable environments. My husband and I couldn't recommend Peter Zimmerman Architects more highly and welcome any and all questions.Read More

Peter Zimmerman Architects designed a new home for our family- It was a pleasure to work with them, and now that we have moved in, the excellence of their design is even more apparent.

Because of this, we were able to achieve a more interesting and exciting design (and now a house!) than we had ever anticipated. Without reservation, I give Peter Zimmerman Architects my highest recommendation.Read More
