"To find someone who is a nice, easy going professional, knowledgeable in design and construction, good communication skills and down to earth person is difficult, however, Sharmila is all this... She is a motivated architect, designer, yet takes what the clients are looking to do and will provide her input as the progress and process continue forward throughout."

"I was referred to Phani at AxisTerra Design by structural engineer I hired for my home renovation project to remove load bearing walls in living room. The referral is like god send in a stressful state where my home renovation project permit is pending for 2 months and San Jose city came back asking for kitchen architectural plans for permit issuance. Phani very quickly helped and provided the design plan in two days. He followed up with me multiple times to get all the details needed to avoid back and forth iterations. Phani shared the plans on the same night at 10 P.M. Once, I confirmed the next, he shared the stamped plans. I already referred AxisTerra Design to a friend for his home renovation project, and without any doubt or hesitation recommend AxisTerra Design for any home renovation project."
