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."

Custom Home Builders questions, answered by experts

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.

Remodeling a house is often less expensive than building a new house. You can expect to pay an average of $100 per square foot when you are remodeling. The cost to build a house averages about $150 per square foot. When remodeling, though, some rooms cost more than $100 per square foot and some cost less. Use a home renovation cost estimator to accurately estimate your remodeling costs.

To get a quote from a builder or general contractor, contact them over the phone or online and explain your project. If you already have house plans drawn up, they’ll need to review them to determine the project's scope before providing you with a quote. Ask for your quote in writing and compare quotes from several pros before choosing the best one for your needs.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

Building a new home can be more expensive than buying an existing one, depending on the housing market in your area. Many homeowners still find that building a new house is worth the investment as they can choose the exact layout they want, as well as to choose their own floors, wall coverings, appliances, and finishes. If you live close enough to the build site, you can also stop by to check on the builder’s progress, which can provide some peace of mind that the project is worth it.
