"Pristine Construction is a class act!! We gutted and completely renovated two bathrooms, and had wood floors installed throughout our home. As part owner and designer, Nathan comes to discuss your goals and holds your hand through the whole planning process if you want. Mike, also part owner of Pristine, is on the job everyday making sure everything looks perfect. Their crew is top notch skilled. Attention to detail is a hallmark of Pristine's crew as well as regarding Mike's and Nathan's expertise. Cooperation and responsiveness from our first meeting and initial plans, throughout construction, and when needing changes makes working with Pristine very easy. Pristine's positive approach in pleasing its customers and offering overall and detailed suggestions makes this company especially great. The crew was here promptly everyday, so unlike the horror stories one hears. Scheduling is well planned and efficient. In addition to Mike, Nathan and the crew, Pristine's friendly and professional office manager, Emma, provided almost daily communication regarding work scheduling and updates. I got their name from YELP and Angie's List and agree completely with all the positive comments. We highly recommend Pristine Construction for your next job with a professional, reliable and friendly residential construction company."

"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."

"Avi from So Cal Builders & Design Inc was our general contractor for our house's addition/expansion. This is the 2nd time we worked with Avi and his team, after he helped us completely remodeled our existing house, we know he is the perfect guy for our phase II of building the addition to our house. Again, Avi is so great to work with! He is very knowledgable on all construction related work and he is always available to help with whatever. He is able to come up with super creative solutions for all our requests/wants, we couldn't be happier with the work from So Cal Builders & Design Inc! My city is pretty strict come to all different types of code, Avi was amazing at managing all the city requests for us, I am glad that he helped with all that stuff for us so we didn't have to worry about anything. The work itself is truly awesome, and Avi and his team are here for us even when the work is completed when we need anything. I completely trust Avi and will for sure recommend him to anyone!"
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.

"My husband and I really enjoyed working with Ben and his team at Creative Home Remodeling Group. Ben oversaw everything from making the plans, getting them approved by the city, scheduling the entire build and doing all final inspections. We really appreciate how communicative Ben was with what day and a time window we could expect the different work groups to come and what work would be done those days. If my husband or I ever had questions or problems with anything that was going on during our construction we were encouraged to call Ben and he helped create a solution that was workable for all of us. We liked that Ben and his team took care of everything from beginning to end and we did not have to hire any additional contractors along the way. We did have to purchase the specific fixtures and tiling we wanted.) We added apx 200 sq feet to our home, which included a bathroom, walk-in closet and room extension. The total process took exactly 1 year from signing our contract to us being able to use our added rooms. (That included making the plans, getting them approved by the city, the build, the installation and final walkthrough with the city inspector.) I would recommend using Ben and his team at Creative Home Remodeling Group to my family and friends. We look forward to working with Ben again in the future."

I'm really enjoying it!"

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