Ani is amazing to work with and her crew irked hard with great professionalism. I highly recommend LGC Construction for your home improvement needs."

"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😊👍🏼"

Persi Homes is full service design and build remodeling company, specializing in ADUs, additions, full house, kitchen, and bath remodels focused on designing and creating captivating living spaces in one elevated and unified remodeling experience. We have re-designed the entire remodeling business model to deliver your project on time and on budget without ever compromising quality. our team of experienced structural engineers, architects, and crew use the latest management softwares to stay on top of your project during the entire process.

"Persi Homes was one of the four OC construction firms I contacted to receive a kitchen remodel quote. Quotes ranged anywhere from $42K to $120K to accomplish the same thing. The scope of my project was to turn my kitchen into an open concept kitchen with a big island that would house an induction range with a vent above it. This required the removal of two walls, raising the kitchen ceiling by removing a soffit and trenching the concrete to gain electricity for the island with the range. I had drawn up my own kitchen design to better communicate my vision. After discussing my design needs and wants with all the various construction companies I decided to move forward with Persi as they seemed to listen best to what my vision was for this kitchen remodel. I chose Persi mostly because I could connect with Amin who was my main contact throughout this construction. Amin was very patient; he listened to what I wanted but still managed to make suggestions for the better when it made sense."

"Just finished a full kitchen remodel with Unique Home Design & Remodeling, and if I could give more than 5 stars, I would. Working with Tal made all the difference — he was honest, organized, and clearly experienced. This was our first big home project, so we were nervous, but Tal’s steady communication and willingness to walk us through every choice really made us feel confident. The team was respectful, clean, and worked incredibly hard. One thing that stood out was their flexibility — when we made a few changes mid-project, they didn’t roll their eyes or nickel-and-dime us. Instead, they adapted and kept things moving forward. The result is a beautiful, functional kitchen that feels us. Highly recommend these guys if you want quality and peace of mind!"

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