“Square One Design provided consultation and building plans for my Vista townhouse project in the Kingsview development. I found the work product and service to be highly professional and efficient. Square One ensured excellent engagement and discussion in producing the appropriate plans.”

“This is my first experience building a house and I was fortunate to have Erin at Square One Design recommended to us. Choosing Square One Design was by far the best decision I ever made. She not only drew up the plans but got involved with guiding us through the permit process.”

– Jerry D.

“The design was completed in a timely manner, on budget, and was more than we were hoping for. We would recommend Square One Design to anyone looking to create a blueprint for a new build or a renovation.”

– Karen and Meri

“When we decided to build our retirement home we were directed to Square One Design here in Duncan. We took a picture and a short description of the house we wanted to have Erin design for us. She spent several hours going over each small detail with us, and as the process went on she consulted with us at every step. Everything was done efficiently and with care. We highly recommend Square One Design.”

– Marlyn and Greg L.

“Time constraints were an issue for us and our house plan was professionally drafted on time to meet our needs. We are happy we used Square One Design!”

– Nick

“As a Cowichan Valley builder, I’ve been a steady client of Square One Design since 1989. In 2015, the opportunity arose to acquire Duncan’s original design studio and I jumped at the chance. I find Erin to be very attentive, incorporating client needs and ideas along with her input to create highly efficient and livable designs. I’ve recommended Square One Design to many people over the years.“
