It was a relief for us to meet the team at Levi Design Build. Their work was exemplary and they always reflected great knowledge in their field. Avi and Eti worked as a great team from the first step to the last regarding our new bedroom and bathroom addition.
Michael S.

When we purchased our home recently, we knew we wanted to have an addition. I had always dreamt of a big master suite with a walk-in closet. We ended up selecting Levi Design Build based on their past projects, Houzz reviews and responsiveness.

It took us years to commit to our home room addition, and it surprised us that Avi was there to guide us along the whole process. We were never left uncommunicated and each member of the Levi team was very careful to respect our spaces.
