About Us

At 45 Architecture, we serve our community through the spaces we design. These places are the setting for the lives we live. We believe it is our duty to design with intent and passion to create spaces reflective of the people who inhabit them. A well-designed space should transcend function to transform a place and improve people's lives. Our work is a reflection of you - your style, your way of life, the site and the budget. We honor honesty, demonstrate active trust and make calculated decisions to create spaces you are proud to inhabit. We approach design by considering each client's personal style and individual needs. Our interactive process allows each team member the opportunity to contribute their ideas, expertise and technical knowledge to create projects that are uniquely tailored to fit the needs and desires of our clients. 45A combines the intimacy and one-on-one mentoring environment of a small practice but with the extensive knowledge of a major design firm. Our reputation is based on the personal relationships we develop with our clients.
