Architect South Lake Tahoe City Truckee Client Review for MASTRIDICASA Architecture Design Studio Residential Designer House Plans CAD Drafting Building Permit Drawings

We wanted to build out an unfinished basement area into a second floor of our home in Tahoe City. We hired Doug at MASTRIDICASA Architecture + Design to formalize our plans into a permit ready set. Honestly, the process was flawless. Doug was communicative, reliable, prompt, and collaborative -- exactly what we were looking for.

Doug spotted the problem places in the plan and we worked together to redesign them to meet code and flow nicely. The plan check with the county went smoothly. We're so happy we used Doug's services and would enthusiastically recommend him to our friends!
