Quadrangle can be summed up in two words: inspiration realized.

Founded in 1986, we are a full-service architecture and interior design firm with projects spanning the commercial, mixed-use, multi-unit residential, content media and retail markets, with expert specializations in areas that include master planning, feasibility studies, accessibility, sustainability and adaptive reuse.

We design the spaces where people live, work and play with insights gained through our process of listening, exploration, nuanced iteration and quality execution. We believe beauty and business go together, and that creative design and sustainability are inseparable. We use the tools of our craft - light, space, materials and movement - to create commercial value. We work with creative entrepreneurs, helping pioneering individuals and organizations redefine their cultures through innovative design and architecture. The diversity of the results this produces is a testament to our collaborative nature. With over 100 awards to our credit, we consistently achieve design excellence.
