"If you want sloppy incomplete and incorrect work hire Hilltop. Bill did not use the products contracted for- used less expensive options without telling us - and hardly ever showed up. The job went way beyond promised finish date. Paid the full balance, Bill then left the work unfinished and ghosted us!"

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?"

I have been in the service business for over 35 years. Originally from Ridgefield CT - starting out in the moving business, learning the great value of listening and learning from customers during one of life's most stressful times. Eventually moving into corporate sales in Manhattan with long hours of commute and travel and starting a family. In 2004 I decided to explore other professional opportunities where I could have more control over my time, energy, and creativity.

"29 stars. 45 stars. You get the idea. I’ve worked with a lot of different contractors in my life, and Rob and his incredible team were head and shoulders above them all. Meticulous, communicative, kind - delivering work that was on time, on budget, and done more beautifully than we ever could have hoped for. Couldn’t recommend more"

FAQs for addition to existing structure building service projects in Southport, CT

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
