They were on hand monitoring the subcontractors and making sure the job was done correctly. They did a great job and we are very gratefully for their hard work!"

"Overall my experience with this company was great! The work that was done was really really good! Our contractor who assisted us was Jose. We added a living space and master bedroom to our home. The additions done look as if they were part of my house this whole time. Honestly it looks way better than I expected. The only reason I rated the company a 4.5 was because there was always some kind of miscommunication between our contractor and his workers. Don t get me wrong, things were always resolved, Jose was great at that. But my recommendation to is to make sure communication is #1. That way the customer is not confused or left wondering what will happen next. There was an issue with his floor guy though, he was rude and unprofessional. BUT the reason I am mentioning this is not to put down the company but let you know that we expressed concern for this issue and it was resolved professionally by Jose and it never became an issue again. The quality of work was top notch! His workers were all pretty cool guys and we always felt comfortable of who was coming into our home to do the work. I highly recommend this company for your next big project😊👍🏼"

Opulent Design Build . One point of contact from Start to Finish. Opulent Design Build takes the complicated process of home designing, building and remodeling and makes it an experience that you will love! There's no need to fear the design & construction process. Opulent Design Build personally handles every aspect of the construction process: design, engineering, site survey, permitting, construction and inspections. We are truly a "one-stop" design-build company.

"My wife and I were looking into adding some square footage to our home as well as remodel. We were going in circles trying to plan and budget and it honestly was one of the most stressful/hardest experiences of our marriage. That was until we stumbled upon Opulent. I do not remember how we found them, but man, I am so glad we did. Eddie and his whole team were OUTSTANDING throughout the whole process. They really made us feel like we were part of the Opulent Family as well as producing real results. They managed EVERYTHING just about perfectly. From dealing with the permit process to helping us figure out what we needed to fill our space with beautiful fixtures to actually getting the construction done. The preconstruction process was so simple thanks to their amazing team and construction flowed so smoothly. The field workers were respectful and clean every day. 10/10 cannot recommend enough. Thank you Opulent!!"

"We hired GWC (Gary Ward Contractor) to remodel our beachside efficiency condo in Long Beach, CA, and we couldn’t be happier with the results. Gary completely transformed our compact space—gutting everything but the bathroom—and brought our vision to life with precision and craftsmanship. Working with our designer and architect, Gary opened up the main living area and installed a stunning, multifunctional Murphy bed system from Resource Furniture (Italy). It doubles as a desk and TV station by day and converts to a bed at night. To offset the loss of closet space, he built a gorgeous custom wardrobe with drawers, plus a built-in refrigerator that blends seamlessly into the cabinetry. He also handcrafted all the kitchen cabinets, installed quartzite countertops, a designer backsplash, new sink and faucet, and repainted the entire unit with great attention to detail. Gary’s work was impeccable—every line aligned, every feature functional. He navigated the complexities of working in a historic 1927 building with experience and care. We always felt he was committed to getting it right. We’d gladly hire GWC again and recommend him without hesitation. Thank you, Gary, for creating a space that’s both beautiful and highly functional."

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