Sustainability through Preservation

Past generations designed with sustainability in mind. With proper restoration techniques, historic buildings, architectural materials, and furniture can be used and enjoyed for another century. We can teach you how.

Renovation and restoration

We renovate historic buildings throughout Iowa, which now are home to businesses and families.

Architectural Salvage

When a building is scheduled for demolition, we recover materials that can be reused so they don’t go to the landfill.

Architectural Resources

We have unique, old growth lumber building materials as well as fixtures, windows, and doors to match historic homes.


Learn to refurbish windows, refinish floors, and more. With proper techniques for care and maintenance, historic materials can last another century.


Quality craftsmanship and artistic design makes furniture, household wares, and fixtures both functional and beautiful for years to come.


Our one of a kind venue hosts a variety of community events, including the Homegrown music series featuring Iowa performers.
