"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."

Addition to existing structure building services FAQs
How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.
Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
