I moved from a farm into a new house in a small town. They built four more homes next to our house and I told my parents I want to do that when I grow up. For the last 33 years I’ve been doing just that . I guess you can say “ I’m living my dream “. I do my best to listen to my clients and help them with the vision they gave for their. Communication from start to finish.

"I would highly recommend them!"

FAQs for addition to existing structure building service projects in Oregon City, OR

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.
