Who are the best architects in Portland, Maine? Here are 15 candidates. Vote for your favorite and tell us who we missed in the comments section.


The waterfront city of Portland is proud of its maritime heritage and committed to landmark preservation. Despite having four major fires in the city’s history, Portland retains much of its 19th century architecture and character. From a trading and fishing settlement to a booming metropolitan city, Portland successfully incorporates a rich history into a modern urban environment. Portland’s revitalized warehouse district and well preserved Victorian residences on the Western Promenade seamlessly connect the past with the present.

Thanks to the finesse and talents of local architects, commercial and residential Portland buildings are designed with consideration to context and an eye toward the future with sustainable design. Listed here, in no particular order, are our picks for the top architects serving Portland, Maine. Who is your favorite? Vote in the poll below, and let us know in the comments if there is an architect you believe should be on this list.
