"We now have a beautiful kitchen. This price tag was on the high end, but that may have been due to either the high price of lumber at the time (Canadian wildfires) or the customer cabinetry that we needed or both. There were a few instances where I was glad we were on sight as I don’t know if the errors we saw would have been caught prior to them being installed. The upfront design and visualization is top notch, as is the quality of the material. The labor used to install was three star at best."

FAQs for addition to existing structure building service projects in Carol Stream, IL

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.
