"Easy to work with, fantastic results. The finish on our saltillo tile floors had badly deteriorated and they were able to ressurect it. And their price was quite reasonable."

"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"

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!!"

Please contact us today to schedule your free estimate. 949-973-3966. With over 30 years of construction experience and proven results we pride ourselves on building new structures, additions and remodeling.

"We recently worked with Andri Construction (owner Steve) to build a custom wine area in our living room, and we couldn’t be happier with the finished product. From start to finish, Steve was professional, responsive, and a pleasure to work with. He took our vision and turned it into reality, offering thoughtful design suggestions along the way. Even though this was a smaller project, Steve treated it with the same care and attention as a major renovation. The work included a custom cabinet for two beverage fridges with a quartz countertop and backsplash, an extended soffit that looks seamless, accent lighting, and a slat wood panel with floating shelves. The subcontractors Steve brought in were skilled, professional, and respectful of our home. Communication was easy, timing was reliable, and everything was done right. We’ve received many compliments on the space and would be happy to recommend Andri Construction!"

"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 Foothill Ranch, 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.
