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."

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