At Newland Construction Inc. we do room additions, second story additions, interior remodels, kitchens, bathrooms and patios. We are family operated since 1982, and our work speaks for itself. You will not be disappointed; we do large or small projects. We also specialize in building new custom homes, and complete remodels. Call us at (714) 981-5729 Newland Construction, Inc., today!

"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. 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. Highly recommended!!"

"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."

"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!!"

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