I am a licensed, bonded, and insured General Contractor with an extensive background in design and construction. I do not just talk the talk, I walk the walk, having physically labored in trades ranging from tile and plumbing, to foundation and framing. To this day, there is seldom a project I will not roll up my sleeves for, be it setting lines for a home addition, or laying out complex tile patterns to be reproduced by my team. I received my Masters in Architecture (M.Arch) from UCLA, where I graduated with distinction. My commencement thesis focused on the California Accessory Dwelling Unit (ADU) legislation, a space that I have become a leading expert in. Building home additions and creating additional housing in the form of ADUs is my lifework: there is nothing more rewarding than delivering a finished project to a client. If you are contemplating a home addition, major renovation, or building an ADU, give me a call. I look forward to hearing from you.

"I recently hired Sklar Construction for a major renovation on my home in Culver City, and I was blown away by their service. From start to finish, they were professional, detailed, and truly cared about my project. The team was fantastic at keeping me updated every step of the way. They answered all my questions and made sure I felt comfortable with the progress. They finished the project on time, and the quality of their work was incredible. My home looks amazing, and I've gotten so many compliments on the renovation. What really stood out to me was how Sklar Construction listened to my ideas and offered great suggestions to make my vision even better. They were committed to delivering top-notch results, and it shows in every detail. I highly recommend Sklar Construction. If you need a renovation done right and want to work with a team that truly cares, go with them. You won't be disappointed!"
