What People Are Saying About Us
Steve and Alana Polacheck
We are so happy we chose 3 at Once Construction for our multiple remodeling projects! Starting with the design choices and throughout the process, everything we have done with you has turned out beautifully. From the master bedroom addition, the complete renovation of all our bathrooms to the new elevator, you and your team have done a wonderful job guiding us through each phase. Thank you!

We couldn’t be happier with our new two-story ADU—an incredible 2-bedroom, 2-bath space designed for both our office and sound/music studio. From start to finish, Bob Charles and his team at 3 @Once Contractors & Construction delivered excellence. Bob was always on top of everything, ensuring the process was smooth and efficient. His crew was professional, hardworking, and well-respected—even local California building inspectors recognized them for their top-tier craftsmanship.
Despite California’s challenging permit process, Bob remained calm, focused, and proactive every step of the way. The final result? A stunning, high-quality space with beautiful finishes that exceeded our expectations. Huge thanks to Bob, Annie, and the entire crew for making our vision a reality!
