"John and his team are ABSOLUTELY TERRIFIC and i would highly recommend. I had just purchased a home that had been partially renovated by the previous owner. John did a full basement finish, outdoor deck rebuild, front stoop/landing rebuild, repaired/installed a garage roof, replaced windows and doors (interior and exterior), and many other projects related to these and others that arose throughout the project. John’s work was excellent, on time, and within budget. He was also friendly and easy to work with, sending me weekly status updates including both timing and budget. On multiple occasions throughout the project he identified unforeseen issues (e.g. rotted wood, debris that needed to be removed, pipes that were incorrectly installed or cut) and kept me updated and fixed the issues. John also handled ordering all parts (with my consultation) e.g. , handles, doorknobs, wallpaper, doors, hooks, etc. I highly recommend John and his team for any project. "

FAQs for addition to existing structure building service projects in Ridgefield, NJ

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.
