Larsen Architects is a established practice whose collective expertise is focused on a singular goal: Create, connect and engage community through architecture.

Our work reflects a clear understanding and reverent respect for the past, combined with an astute insight and open minded embrace of the present and future. Our team of experienced and talented architects & designers represents the full scope of capabilities required to create better, more productive and more sustainable communities.

Every project we encounter and embrace is thoughtfully evaluated, thoroughly explored and responsibly created. We approach every project on its own merit, with a deep understanding of how the project will serve the client to balance, enrich and advance the community in which it will exist.


Passion and the pursuit of design excellence are the cornerstones of our firm. While we have grown over the past three decades from a small team of young architects to an established practice with a global perspective, we remain a community-centric partner to every client in our portfolio.


Today, every organization must be considerate of, if not concerned about its influence on the environment. Sustainability isn’t just a good idea, it is a necessity. Larsen Architects is dedicated to addressing environmental issues and opportunities on every project in every community at the earliest possible stages of development. Our LEED™ Accredited staff can evaluate and guide your project through to USGBC certification. We also embrace ‘practical green’ where the environment – and the bottom line – can benefit from this best practice.


Great architecture results from great architects. Likewise, great communities result from great architecture created by passionate and skilled architects who are educated and invested in understanding architecture’s role in the community..

Our staff provides full architectural design services to both private and public sector clients. The breadth and depth of our experience results in a thorough and balanced discipline.
