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 specialize in residential and commercial projects. Customer centered building with a focus on establishing and maintaining relationships. Or team builds on time and on budget. 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!"

FAQs for addition to existing structure building service projects in Fountain Valley, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
