"We recently completed a full remodel project with Trey and Bob at Dwell Develop and Design, and the results were absolutely phenomenal. Every inch of the remodel reflects exceptional quality and attention to detail — it turned out even better than we imagined! From start to finish, Trey and Bob went above and beyond. The customer service was outstanding throughout, and their professionalism and craftsmanship are second to none. What really set them apart was how they welcomed our creativity — they truly allowed us to dream big and brought our visions to life with precision and care. We’re so impressed that we’ve already partnered with them again for our upcoming double garage and MIL apartment project. If you’re looking for a team that listens, collaborates, delivers top-tier work, and makes the entire process enjoyable, Trey and Bob at Dwell are the ones to call. We highly, highly recommend!"

FAQs for addition to existing structure building service projects in Keller, TX

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.
