What clients say about us...

Our commitment to our clients shines through
in what they have to say about us.

Working with Brian was an absolutely wonderful experience. He quickly captured our desires and made them happen seamlessly. We would recommend him and have recommended him to our friends and family.
Etta W — Homeowner
Design on the Square was the perfect partner for our ADU garage renovation project. Brian Viehland is a talented designer and was creative, competent, patient, and flexible. He provided us with multiple options and solutions in real time. Brian was always there when we needed him, and we could not be happier with the end result. We will not hesitate to hire him.
Pat M. — Homeowner
Brian, it is clear to me that one of the best decisions I have made is to have you on my team. I appreciate how detail oriented you are, punctual, how you advocate for me, how you inspect and question everything happening here. It fills the whole process with confidence and high expectations. My deepest appreciation.
Regina C. — Homeowner
We used Brian to redesign the kitchen and dining room of our new home. The stairs were in a weird spot and we could not figure out what to do - but Brian came up with a genius idea that resulted in a gorgeous kitchen and essentially our dream home. He was responsive, kind, creative, funny, and a top notch person.
Rachel R. — Homeowner
Design on the Square's owner Brian is a highly recommended professional for your architectural projects. Brian is very patient, super helpful, and is knowledgeable about several industries and code requirements and is able to pass this knowledge to his clients in a simplified way. He guided us through the steps to ensure our project will meet all government compliance prior to the beginning of our project, this saved us a lot of time.
Abby G. — Homeowner
We met with three architects to discuss our project before hiring anyone. We enjoyed meeting with Brian Viehland and liked his ideas. We had a good relationship with him through the design and building process. Brian was willing to work with us and hear our ideas on the design of the renovation of a master bath and construction of a new master bedroom, mudroom and two-car garage.
Steve G. — Homeowner
Brian is just wonderful! He came to our home and listened to what we needed and wanted in our kitchen renovation project; he gave us suggestions and alternatives to consider and gave us beautiful plans to work with. I cannot wait to start the project and see it finished! He is very professional, prompt and personable. I highly recommend Brian for any project you want to do!
Sue G. — Homeowner
Brian was very responsive, kept his time commitments, provided opportunities for several discussions, discussed the goals of my project and provided support for determining appropriate estimates. My new kitchen layout was built in phases, I love the space and it couldn't have been transformed without the design options provided by Design on the Square.
Nelida V. — Homeowner
