We offer free estimates for any size project : kitchens, bathrooms, exteriors, roofing, additions, decks, bedrooms, basements, or even an entire home. We also provide design work with multiple photo realistic renderings and 360° views along with full floorplans and elevations, so you can really envision your new space before you build it. We help to guide our clients through every stage of a renovation so that it comes in on time and on budget. Call us today at 203-644-9124.

"I highly recommend DDR. There are so many contractors out there and it is difficult to know what youâ ll get when you hire someone, from the quality of the work to the level of communication. This team did a great job from start to finish, and delivered a beautiful new space for my family. We selected DDR after getting multiple bids to update our walk-out basement into a more livable space. Key in this selection -- the price was competitive, and the team seemed attentive to the project needs as outlined. I had a tight budget and relatively aggressive timeline for this project. Admittedly the timeline was impacted by a few things that were out of DDRâ s control, including the Town building inspectorâ s schedule and a delivery delay (a new window arrived damaged and had to be reordered.) Nevertheless, the team stayed on budget and delivered a wonderful new basement. What a great project team -- led by Alex, the team (including John + Angel) truly transformed a dark dingy space into a bright fresh room. Alex was very thoughtful in suggesting options that would improve things and was exceptionally attentive to detail. He was super responsive to any texts or questions. In particular, I appreciated his high level of â perfectionismâ in how the finished product turned out. For phase 2, we need some custom cabinetry built for the space and I look forward to having the DDR team return to work on this next phase."

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite.
