They reconstructed and restored an upper rear deck, dining room porch and far-back lower deck, repaired a front dormer, repaired an entire front & side façade and then recovered it with new clapboard, installed millwork around new Pella windows, installed real shutters, & a far-back canopy. They rebuilt an elaborate rear yard fence and built a privacy gate. It is our pleasure to write this review, we feel lucky to have them available."

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