"It was a pleasure to work with Eric, we hired him for a complete backyard renovation which included tree removal, leveling the surface and place pavers and a deck on top. Also built a retaining wall. The work came out very nice in part because of the great design ideas that Eric gave us. The project ran into some unexpected issues that Eric was able to overcome nicely. We were impressed how Eric handled the project and met all the deliverables, also his team was extremely polite an professional. Our backyard now looks like the ones advertised in magazines. All this led us to start a new project with him to replace the cracked driveway with nice new pavers."

"We had our two bathrooms fully remodeled by Golden View 4 years ago, and were very happy with the results. Recently we noticed a leak from the shower in one of them that was affecting the nearby flooring. Asaf and the team really came through for us, they diagnosed the problem - a shower pan leak - opened the walls to clean and mitigate mold, planned and executed a partial demolition and rebuild of the shower including an improved method for waterproofing, and restored the bathroom and walls back to original condition and full functioning. All of this and they didn’t charge us, since Asaf told us he wants to stand behind their original work and fix problems arising. Five stars for sure! "

FAQs for addition to existing structure building service projects in Union City, CA

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.
