decades of service + experience

In 1898, Andrew H. Foss, a 22-year old Norwegian immigrant began designing and building railroad depots throughout southeastern Minnesota. From that start, FEH DESIGN has grown into one of the region’s longest operating               Architecture / Engineering / Interiors firms.

Our design practice is intentionally diverse complemented with specialized expertise in several markets. We thrive on the energy of the variety of projects and clients that we serve. Every project is an opportunity to learn more about an organization, a person, a process or a community…and each design is an opportunity to test ideas, expand our thinking and positively impact that organization, that person, that process or that community. This is what continues to drive us.
