Henry Showah Construction can skillfully design and remodel all types of projects. We take pride in our attention to detail. Please give us a call to set up an appointment.

"We contracted Henry as our GC to lead a 175K addition/renovation of our home. We added a master suite (w/ walk-in closet), another bedroom, a play/rec-room, and a workshop. We also took down the walls of an existing room to open up the common areas and built a hallway of pocket doors. We found him to be a great communicator. His subs were professional and courteous. Highly recommend him for others and would be happy to hire him again for future projects."

"I recently had an asphalt driveway put in. The crew was very professional. The driveway is smooth and very happy with the quality of the new driveway. They even went above and beyond and put in a small drainage area for water runoff. It has definitely improved the appearance of my home."

"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."

FAQs for addition to existing structure building service projects in Sandy Hook, 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.
