"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."

"My husband and I had several appointments with different contractors. When we met with Terry, we both felt he was very knowledgeable in all areas, and had very good pricing.

Moved dining room to former kitchen ( swapped rooms) 3. Dining room: (former kitchen) removed wall for open concept 4. New flooring 5. Stairs: replaced carpet with laminate, replaced rails 6. Living room: Added a window seat with storage 7. Living room: Added entertainment wall with shelving 8. Living room: Added modern fireplace 9. Added windows, moved sliding glass door WE LOVE THE FINISHED PRODUCT!! The project was right on schedule (5 months) and we didn't go over budget. As it is expected to run into a few snags during ANY renovation, Terry and John were very responsive and quick to resolve any issue. They were on top of the problem, and resolved with excellent results. We get a ton of compliments on our home. Thank you, Terry, John and your crew. You've exceeded our expectations.

"My bathroom was remodeled by Moriah. It is now much more modern and minimalistic than it was before. I have new flooring, sophisticated recessed lighting, LED lighted mirror and a brand-new floating vanity that has a spa look with the wood door and above counter sink. The entire bathroom was painted a pretty blue color including the walls and ceiling. Even the door was re-painted white. I also have a new toilet bowl. I already had an existing shower that had recently been installed. Fantastic job!"

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