Daniel Koplowitz, Architect
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."

Tiderunner Engineering & Design PC
I provide residential structural engineering services to both homeowners and home improvement contractors. These services include plan preparation, design of structural members, structural evaluations of existing buildings, review of plans prepared by others, design of sanitary systems and on site drainage systems if necessary. All work is done by me, a registered professional engineer in New York, and I also conduct inspections and evaluations.
"Was Awful. Measurment's were off. Plans were incomplete. After he measured the rooms, we had to remeasure the rooms ourselves and send them to him. I then had to go to his house to pick up the plans. I submitted the plans at which time I was told that I needed to get then done again by a professional. Held up the construction by several weeks. Save your money. Do not use Lou."
