"Our goal was to build a structurally safe garage storage loft. Juan and Julian were a great team to work with. They were very professional and organized- they gave us a quote and clearly communicated what the plan would look like from beginning to end. They guided us on the items that we needed to buy prior to starting the work in order to complete the project within the estimated time. They suggested modifications that were minor fixes but made the layout make more sense in terms of placement. Their crew finished a day ahead of schedule. They kept a clean work site and the quality of the results were great. I would gladly work with them on another home project in the future!"

FAQs for addition to existing structure building service projects in San Martin, 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.
