The work quality was outstanding, with great attention to detail. Michael and his team were professional and efficient!"

"We just had our kitchen completely renovated by Beverly Builders Group, and we couldn't be happier with the end result! Lawrence was our contractor and he fully brought our vision to life!!! My family and I went out of the country while the kitchen renovations were done and Lawrence took care of everything for us. He was super easy to get in contact with when we needed him or had any questions. He honestly went above and beyond for us and I loved how transparent he was about the job along the way. I've worked with other contractors in the past that weren't so honest and it was such a nice experience this time around. Emily was our project coordinator and designer and kept us updated daily on what was happening. We were always in communication with her and she overlooked our shopping list of all appliances so nothing was missed on our installation dates. Their team was amazing and I highly recommend them to anyone who wants the best! We were so happy with them that our master bathroom"

Our mission at Rebuilt is customer first.. construction second. With over 15 years of experience in the residential construction industry, we understand the great responsibility and honor it is to work in your home. We take great pride in our work, and even greater care of our customers.

"I hired ReBuilt for a full-gut interior renovation. From the first call to the final site clean I felt taken care of. The estimate was detailed and clear. The in-house designer, Kaitlin, implemented my ideas and tactfully injected a few of her own to create a beautiful finished design. My Project Manager Ricardo was onsite daily and posted logs on Buildertrend, the companies software system. It was great seeing the updates! He also kept adherence to the 16 week schedule and overcame some minor obstacles from the city and a few materials vendors. All in all I'm very happy with the outcome and would definitely recommend ReBuilt!"

"Efrain and David are fantastic! When our contractor was suddenly unable to continue with the job, David took over with a great positive attitude. He persistently worked with the city to get the building permit, finally ending a tedious 10 month process. Crews were here working every day. Each one of them was considerate, conscientious, and demonstrated a strong work ethic. Efrain and David communicated with us most days and were always accessible to us. My ADU is adorable and just what we wanted and I am sure that many contractors could have pulled it off. The important thing about Olalde is that they truly care and honestly want us to be happy."

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