"When I found IND Construction and decided to move forward with them, I felt at ease. Every single step, from design to architecture to clearing out an old shed, to building the structure and final touches, was done with care. That meant a lot to me and my dad, especially now, with COVID-19. The workers were thoughtful and all my questions were answered and attended to. At the end of the day, I was really thankful that my guesthouse was built. It gave me a sense of relief and accomplishment. When I look at it, I think of my mom, who had wanted to build a guesthouse. I think she would have been really happy."

"After several long years of designing and permitting our home remodel during the pandemic, we were searching for a good contractor to build out our remodel and second story addition. Avi and David were wonderful; very thorough in explaining the process, answering all of our questions, and settling on a price that was reasonable and within our budget. During the building process, David was very responsive, available, and receptive to changes and last minute decisions made along the way. The project took longer than anticipated and there were some unexpected setbacks, but David and Avi worked quickly to fix issues and keep the project moving forward. At the end of the project they were very responsible about making sure we were satisfied with every last detail before completing the project. Our new home is beautiful and we're very happy with how it turned out, thanks to David and all the crews at So Cal Builders."
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

"We just finished a four bedroom/ three bathroom full remodel in Santa Monica. We are very happy with the end result. Nathan, who is the owner, was very involved in all phases of the job. Nathan got the job done on time. The workmanship and attention to detail was great. He had good communication and relationship with his team. Whenever we had a concern or question, Nathan was easy to get a hold of and handled it quickly. We were worried about the process of a remodel with all the stories you hear about bad experiences. But Nathan made this so easy on us and we would definitely use him for any future projects."

"HIC builders is a family owned company, and they did a terrific job at my house. We added an ADU above the garage, remodeled two bathrooms, and did other extensive work on the house. Abraham, the field manager, was responsive and available, flexible when plans needed to change to accommodate structural issues that we discover as the project progressed, and answered my endless questions. The workmen were always on time, courteous, and cleaned up the site every day before they left. Probably the easiest way to find out if HIC can provide what you want is to call Abraham Moryossef directly (818 850 5062) and chat. I know it will be a good investment of your time. They are terrific!"

"I recently worked with HA My Design to build an ADU, and I could not be happier with the results. Golan and his crew were always on time and worked hard to ensure the project was completed within budget. The quality of their work was excellent, and they were quick and efficient. I highly recommend HA My Design for anyone looking to build an ADU. Their one-stop-shop showroom, covering 5000 square feet, made selecting finishes a breeze. I will definitely refer them to friends and family!"

"Relationship Building and Strategic Thinking are how I would describe Home Renew 360. This was my 1st major home improvement project. Viktor Hohlov was my project manager and he has been beyond fantastic. He kept his promise to be with me from day 1 of the project to the end. Adaptability, connectedness, developer, harmony, individualization, positivity and relator are how I would describe Viktor. He heard my comments and concerns and communicated that to his team and contractor. He was constantly checking on the sites and showed great accountability to ensure services and jobs were being done with high standards. Idan Mizrahi was my contractor for the project. Idan and Viktor work amazing together to make sure that I was satisfied with the outcome of what was being done. He was accommodating in meeting with me and showed me a short clip of a video of the whole process of each work. Analytical, strategic, focus and communication were Idan’s strengths. The team that was working on my houses were friendly, respectful and accommodating. They were there on time and cleaned up at the end of the day to ensure safety and cleanliness. My tenants who live there have reported how pleased they are with the crew and the communication they received. The houses look amazing with small details that they were able to exceed beyond my expectation. When you are ready to do your home improvement project, contact Home Renew 360 I highly recommended that you work with Viktor Hohlov and Idan Mizarahi."

"R Design was great. Ramy was able to match my existing plaster pattern and paint design. His crew was professional and they provided excellent service. Most importantly, they were willing to come back and make things right after I pointed out a few inconsistencies. We hired them to do additional work while they were here, which helped out tremendously. I would definitely hire R Design again."

"My husband and I just finished a remodel of our guest house in Sherwood Forest. We used a company called Universal Home Design Inc. The contractor and owner of the company Ouriel Lousky was most professional in every aspect of the job. His crews were timely and most efficient in every way. He had his subcontractors lined up so the job was never lagging behind. I would recommend him to anyone who is planning on a remodel or a renovation. Mary V."

FAQs for addition to existing structure building service projects in Simi 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.
