Licensed Contractor, we are a small company but deliver big results, let us give you a quality project for less. We offer 12 month 0 % financing OAC. We accept all major credit cards. We also handle all insurance loss claims with our own in house adjuster. Call us before or after a lose and let us get you what you deserve, before you say yes, let us give you a second opinion we have acquired our customers thousands of dollars more on their claims.

"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."

"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. Needless to say, we chose Newland Construction. From day one, we felt comfortable and at ease. Renovation Project: 1. Moved the small kitchen to our large dining room. 2. 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.

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.

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!!"

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