"We recently had our kitchen remodeled and expanded by removing a wall to create an open floor plan. The contractor did an outstanding job. Throughout the renovation, they kept the site immaculately clean, which was much appreciated as we were living in the house at the time. They were always respectful of our space and provided knowledgeable recommendations for suppliers and installers. The entire process was handled professionally, and we are thrilled with the results. Highly recommend!"

"The initial build went reasonably well. We did find problems which they did come back and fix. I noticed a railing support that was cracked. I was told that I must of done it, that was that. The plugs that cover the screw holes in the stairs are falling out. I looked for some at Home Depot, but couldn't find the right color. I still had Chase's cell #, so I texted him and asked if he could send me some plugs, and I would do it myself. No response. Tried again the next day, still no response. I'm not surprised. Aging the build was decent, price was higher than most. Now that nearly 2 years have gone by, and customer service should be anticipated, nothing. Never again."

"We added a great room, entryway, deck and second floor room to a ranch. Kip has a great design sensibility and we worked together without an architect to come up with a plan. We've been extraordinarily happy with the result; we love the house. The older section works seamlessly with the newer section. Kip pays attention to details. After the work was done, Modern Habitat has been responsive to whatever issues that arose. We are truly appreciative!"

FAQs for addition to existing structure building service projects in Northborough, MA

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.
