"I hired Progress Contracting to complete a second story addition to my home in Westwood. Tim and his crew were excellent. Their work was of high quality, they were thorough, reliable, and great to work with. Tim was very capable of handling the job, which was extensive, and he was more than willing to work with me on changes that I requested as the job went on. I would highly reccomend Progress contracting."

"Competent and reliable team, solid schedule, very professional result. Neighbors see their results and often seek their help. Straightforward and knowledgeable. Comfortable interaction since 2015. They stand behind their work and take pride in it. We have a house built in 1838 which needed external repairs to deal with weather, recently becoming more severe. 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.
