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.

  • FEH Design has been my home for the last several years and has really helped me become the designer I am today.  I have never been limited in what I wanted to learn or explore.  From the day I started I have been involved in all aspects of the project.  I love meeting a client in schematics, helping them all the way through the drawings and construction, and finally seeing how much they love the project in the end.  FEH has given me so many new relationships with owners, product reps, suppliers, and contractors that I don’t think I would have gotten at other places.  FEH Design is a very welcoming family of great people.
