"Mark Brand asked all of the right questions and worked tirelessly with the city permit department to make sure everything we wanted to do would be approved. Beyond being amazing on the phone with the city, his design fit with our mid-century home and anyone who has seen it is amazed at the transformation of our small back yard. We started this project with Mark in 2019, long before COVID-19, and completed the major construction in October of 2020. The actual construction began in May 2020 with demo, to completion in October 2020. Mark and his staff were with us through the entire process, communicating with our Contractor and Pool installer and keeping everyone in the loop and on track. I had never worked with an architect before, and feel grateful that my first experience was with Mark Brand and his team. Fees are explained up front, and although the fees were a healthy part of our budget, I know I got what I paid for! Communication with email and phone calls, as well as site visits were always timely, with any issues explained and problems worked through and resolved to avoid delays."
