Daniel Koplowitz, Architect
I established my practice in 1988 with a focus on Historic Preservation and exterior restoration. Over the 40 years of practice I have gravitated toward renovations and new construction that impact older structures or historic contexts. My practice is eclectic and a result of varied experience. In part, living overseas, in France, Italy, Brazil and Belgium had the most influence in my becoming an Architect. I began my professional career in Washington, DC and came to New York after receiving a Masters degree in Architecture specializing in historic preservation. Whether restoring historic buildings or expanding and renovating others, I am committed to achieving a result that serves my clients' needs and provides beauty with lasting value. I continue to pursue preservation ideals, not only to preserve the built environment, but to recycle, restore and create a healthy built environment. Energy conservation and sustainable architecture is rooted in the preservation
"Our experience with Preservation Design Group was first rate all the way. From start to finish, the architect was responsive, attentive, creative and professional. We were impressed by Dan Koplowitz's attention to detail and willingness to listen to what we wanted to achieve with the project, which added over 1500 square feet, relocated bathrooms and renovated and enlarged the kitchen. Dan worked diligently to meld the exisiting house with the new and provided plans that our town approved without requiring modifications and the building dept. is quite strict. The builder Dan recommended was excellent and they worked well as a team."

High end architect specializing in making a house feel like home! I make people’s dream homes a reality. There is nothing more satisfying to me then improving the quality of life for my clients and giving them a house that they are able to make into their homes. I have been a licensed architect since 2015 and am currently registered in Rhode Island, Connecticut, New York, Maine and Massachusetts. With my NCARB certificate I am able, if necessary, to obtain reciprocal licensure throughout the country in a short time period. I am inspired by our local built environment, humble materials, classical building forms and traditional building details. I have a strong interest in the reinterpretation of classical building forms, blended with contemporary open floor plans. I have a stronger interest in helping to guide my clients to ways of improving the quality of their lives through adapting the built environment to meet their needs.
"He was pretty responsive, caring, look into our concerns, manage to work everything, willing to work on the plans."
