"Shilpa working with her structural engineer completed all the architectural and structural plans and calculations for a 400SF single story addition, complete with drilled piers and grade beams, in just over two months for submittal to City for review. Shilpa is very easy to work with and is quite readily available to fit my work and project schedule. Shilpa is very responsive to my comments and timely completion of required documents. Cost is reasonable. City has few review comments and issued permit for construction. I would definitely retain Shilpa again when the need comes up."

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."
