The staff at Studio21 is well experienced in designing additions and renovations, single and multi-family homes, fire restoration plans, and commercial projects. Our broad range of experience shines in our portfolio, highlighting over 35 years of projects. Our continuing education in the field ensures that we are current with trending designs and the latest products on the market.

We provide superior service to our clients, and the source of this quality is our personnel. We use a team approach in our architectural practice. The diverse background of the staff members blends into a cohesive whole to provide our clients with services tailored to their specific needs. Each member of our team is critical to the success of your project. Our goal is to design the home or project of your dreams, and bring your vision to life, without compromising quality.



“Design Your Own Sense of Home” is our philosophy in the design of a custom home, and our attention to detail is what sets us apart from the standard. Details are also what turn a house into the place that you will call home. A custom home should be a reflection of the people who will live there. Our design services are tailored to the needs of our individual clients.


studio21 architects provides design services for a range of commercial projects, from relatively small projects such as tenant plans to more complex projects, such as restaurants, auto dealerships, ice arenas and multi-story office buildings. Our design flexibility allows us to provide the optimum solution for your commercial project.

Additional Services

studio21 architects offers additional services to help tailor your project to your specific needs. Our goal is to make the design process as simple and straightforward as possible. These services include renderings and animations, as well as land planning assistance. We provide you with all the tools necessary for a successful project.


We had a fantastic experience working with the staff of Studio21 Architects. We had a bit of a more challenging job, because we were building a home out of state, but there was nothing difficult about working with this firm. We took our time and were never rushed in the extensive planning of our “dream home” and it showed with the completion of our home.

The entire process was very enjoyable and we would and have recommended Studio21 Architects.

My wife and I contracted studio21 architects to design our basement and outdoor living area. Bill and his staff were thorough and creative in their design process. We are very happy with the end product we received from their designs.

We had the pleasure of working with Bill with studio21 architects when we built our first home.  What we thought would be a stressful and daunting process was an absolutely pleasurable experience. They listened to us with great attention and did not miss any details that we wanted included. It was amazing to see how they pulled our idea of an ideal home from our minds and conceptually put them on drawings.

We also outsourced the construction progress supervision to them, and they managed the process from start to finish for us.  Their ownership of the process was amazing; supervising the project as if it were their own home. They gave us input and suggestions as construction commenced, most of which we incorporated, and the end result was stunning.

We have lived in this home for 5 years, and we are very pleased with the layout, openness, aesthetics and functionality.  Studio21 Architects keeps in touch with us, asking for feedback as we continue to dwell in the house.  Studio21 Architects is not just an architectural firm, but a firm with vision, creativity and engineering elements all rolled into one. Above all else, the firm has a great team of individuals who aims to please their customers.
