"I wanted to add a garage and didn't have a lot of space. I live in a landmark district in Denver and they can be very difficult and it's hard to find someone who would even deal with them. But Bryan and his guys braved the storm and got the garage done and put in a custom concrete patio to maximize space. Loved all his guys and would gladly use them again"

They really had a good way of making us feel comfortable; almost like having family here at the house because we never felt intruded upon. The job was timely, they were consistent, they went above and beyond ideas of thinking outside the box. It was like having a design team as well as the construction team. They are just the best. Fantastic. Perfect 5 out of 5 the highest rating they can get."

FAQs for addition to existing structure building service projects in Castle Rock, CO

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.
