Arched Walnut Door Showcases Iowa Ecologists’ Home

The arched front door of Driftless Bluff Cabin in Decorah, Iowa, draws attention to a modern rural home built for ecologists Amy and Jason Husveth. Designed by Imprint Architecture and Design, the structure rests on a 25-acre parcel the couple has been restoring since 2015.

Family-Sourced Materials Shape the Entry

Amy requested a walnut door sourced from her family farm. Her father harvested the timber, while her brother fabricated the metal lining that frames the curved opening. The metal lining not only secures the door but also showcases the family’s hand-crafted expertise.

The overhang begins with a straight edge before sweeping down, forming a sheltered porch. Dark metal highlights the curve, and a small circular window adds character to the walnut surface, allowing natural light to filter onto the entryway.

Modern Form Meets Rural Tradition

The house follows a simple geometry of two adjoining gabled volumes, pale vertical siding, and dark roofs that echo familiar farm structures. Large windows and minimal detailing give the building a contemporary feel while respecting the surrounding agricultural context.

The curved entrance stands out against the straight rooflines and rectangular windows, providing a distinct visual marker without altering the overall rectangular footprint. Its presence creates a welcoming transition from the environment to the interior.

Large Glazing Connects Interior and View

With an approximately 800-square-foot footprint, the residence includes one bedroom and one bathroom. Corner windows admit abundant daylight and support passive solar heating, a strategy highlighted in passive solar design. The generous glazing also contributes to the exterior aesthetic; dark frames contrast with the light siding, breaking up solid walls and giving the structure a lighter appearance amid open fields.

Pale interior walls and wood floors create a neutral backdrop for the surrounding countryside. Corner-mounted windows offer views in two directions, expanding the sense of space inside and reinforcing the connection between indoor and outdoor environments.

The Husveths bought the land in 2015, adjacent to Amy’s parents’ cattle farm. Decades of row-crop farming had left the soil eroded, prompting the couple to plant pasture grasses and nitrogen-fixing legumes for rotational grazing. Future plans include restoring native prairie on the bluffs and surrounding acreage.

Construction was carried out by Ark Seiler, with windows supplied by Marvin Windows and steel work by Herman Welding. The project showcases how personal history can inform contemporary rural architecture.
