"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."

"The remodeling of my guest bath went very smoothly. I had few ideas as to what I wanted, but thanks to Nathan's design help, I was able to select the items that fit my concept. Many reviews talk mainly about the job and the results, but there is one important area that is often neglected: the working crew. Without exception his guys, besides being highly competent, were both respectful and considerate at all times. I strongly recommend this company!"

"We needed a bathroom remodel along with fixing a few older issues, and after speaking with a few contractors, we chose Buildwright. Edoe took the time to explain everything clearly and helped us understand what needed to be done. The crew worked carefully and even repaired some problems we had not noticed before. Communication was great throughout the project, and Edoe made sure every detail was done right. The bathroom now looks clean, modern, and much more functional. He also followed up after the project was completed to make sure everything was in good condition, which we really appreciated. Highly recommended! ?????"

"Our initial meeting with Suj was great. Initially, we had in mind a much larger job. He had quoted us $3000 for the closet demolition / wall rebuild (non-load bearing), packaged with several other items. Together with the fee for drawings ($4000) and permits, this was a bit higher than we anticipated. However, we decided to go with Suj due to his responsiveness and professionalism. Out of our other quotes, Suj’s pricing was middle of the pack - not the cheapest or most expensive. When the drawings were complete and evaluated, he gave us an updated cost of $6000 over text message. The scope of work had changed, and this was no longer part of a bigger project - understandable. The issue was when he gave us the official estimate a week later and up’d the price once again to $9000. When asked what happened, his exact words were “well, I need to get paid too”. He had weeks to consider before quoting the $6000 and nothing had changed since then. The extra $3000 may be insignificant compared to most renovation costs, but for us in our first home, this was back breaking. We continued with Suj since we were already locked in and well past the 3 day cancellation period. Their work for the most part was exceptional. The new wall blended perfectly into our existing structure, and the ceiling patch was also well done. The problem here was the floor. They had dug up a 1” deep pit in the floor, likely to remove the wall studs. However, they did not patch the floor or even let us know this was going to be an issue. We were never told about the pit until I decided to check in on their progress one day towards the end of the wall build. This required us to pay a handyman to come in next day on a weekend to patch the concrete since we had cabinets being installed the following Tuesday. Suj was aware of this and did not believe it pertinent information. Overall, Suj and SoCal Builders do quality work, but the issues in pricing consistency lost us before the work even started. Not even telling us that we’d be left with a 1” deep pit in our floor after was another huge issue which should’ve been brought up much earlier. This was our first experience with a contractor and I’m not sure if this is typical or not. However, it’s enough to make me doubt I’d contact them for any future work."
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.

"Nathan impressed from the time I first met him. He was far more professional than other contractors in terms of describing how his company works and what I should expect if I worked with him. He also has a nice showroom where you can look a variety of cabinets in different styles and colors as well as countertops. We ended up getting a countertop that he suggested. We would never had picked it on our own but it ended up looking amazing in our kitchen. We had him do a complete remodel of our kitchen and one of our bathrooms. The guys on his crew were always prompt and showed up as scheduled. His foreman was both a good communicator and listener. Whenever we ran into an unexpected issue, they communicated clearly what additional costs would be involved (if any) and how much additional time it might take. The cabinets he installed were custom made but did not cost more than the pre-fab ones you can buy at the large home improvement stores. They are of high quality and well constructed. I actually saw his cabinet guy using a small caliper to make sure the door distances from the cabinets were all even! Lastly...here's something you'll never hear about a contractor...he finished AHEAD of time! Nathan's company are straight shooters and very skilled craftsmen. I would work with them again."

"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!"

"Eran and his team were great. I had agreed to remodel my bathroom before moving in to my new house. It turned into quite an adventure once structural problems were identified during demo. Eran worked with me on trying to keep the bathroom timeline on track as I worked to get other contractors in to fix the other problems.  And they worked above and beyond in motivating me when the other contractors were late. We did run in to a slowdown at the end of the project and better communication would have been recognized - the problem was with a supplier outside of Eranâ s control. The end result was a slip at the end date for the project. Once everything worked out, I was very happy with the end result."

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