Douglas Marshall Cooper Associates is a full-service design and construction firm whose practice encompasses both new and existing buildings of residential and commercial use, as well as speculative housing and development. Mr. Cooper’s office is located in Pound Ridge, New York and includes a staff of himself, an associate partner, three assistants and a host of carpenters, masons, and laborers, in addition to various subcontractors that work on projects small to large. Douglas Marshall Cooper Associate's roots are based in Construction, Design, Real Estate Investment and Development & Construction Management. Our portfolio includes a wide range of work across these fields. Our uniqueness comes from understanding what it is to be the Owner, the Developer and the Builder –- a trifecta that is evident in DMC Associate's core portfolio of prestigious residential, commercial, and corporate projects. Douglas Marshall Cooper Associates, LLC...a solid track record. A powerful future.

"I wish I could give zero stars. We hired Douglas for a kitchen remodel which involved installing a kitchen island, pantry, and all the related plumbing and electrical work. The communication between Douglas and his carpenter was terrible. We submitted sketches and agreed upon the design for the cabinets which were meant to be overlaid. When the island arrived, the cabinets were inset which did not match the rest of the kitchen. In addition, the kitchen island has split and cracked at more than half of the joints. The pantry cabinet has split and areas of unpainted MDF are showing. We have needed to paint and touch up many of these spots. Regarding the plumbing, we have had multiple significant leaks from piping and tubing that the team installed. Water has leaked even through the floor and into the basement. Upon review from other plumbers, all have confirmed the parts used were cheap and of low quality, and the workmanship was subpar. After a major leak in the middle of the night, we reached out to Douglas and respectfully voiced our issues and complaints. He ignored us for a full month, and then instead of simply stopping by to take a look at the problems (which would have been the first major step to alleviating our frustrations), he responded in a despicable manner. He even included the following quote from his lawyer, He laughed saying that perhaps you lost your job (due to the CoronaVirus) and were probably scrounging for any money you could scrape up. Who would want to work with someone like this?"

FAQs for addition to existing structure building service projects in Bronxville, NY

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
