LHB is an engineering, architecture, and planning firm known for our design leadership and client loyalty. Our Performance Driven Design focuses on measurable outcomes. We are experts in: public works, pipeline, industrial, housing, healthcare, government, education, and commercial design.

LHB has civil, electrical, mechanical, and structural engineers, land surveyors, architects, interior designers, and landscape architects. We offer you a full-service firm that can complete all facets of your project using dedicated, in-house teams drawn from our 250-person staff. Our offices in Duluth, Minneapolis, and Cambridge, Minnesota and Superior, Wisconsin serve clients throughout the North and into the Midwest.

Founded in Duluth, Minnesota in 1966, our first project involved the Duluth Arena (now the Duluth Entertainment and Convention Center) and 50 years later we are still working with that client. The practice of nurturing long-term relationships by listening to client needs and delivering high performance projects stayed with us.
