"From start to finish, I was exceptionally pleased with the service provided by Treasure State builders. Some understandable supply chain issues related to Covid, but the build team communicated with me throughout. The team of Tom, Chad, Jeff, and Spencer, completed the work in a timely fashion, performed appropriate work site cleanup afterwords, and were a pleasure to deal with. I have other projects pending until spring, and I will definitely hire Treasure State builders again."

FAQs for addition to existing structure building service projects in Corvallis, MT

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.
