For most of the 20th century, the Eitel building in Minneapolis housed the sick. Eitel eventually fell into disrepair, and in October 2006, Farmington Hills, Mich.-based owner and developer Village Green Cos. began redeveloping the former hospital, giving it a new life as Eitel Building City Apartments (pictured here), a 212-unit luxury property for Twin City urbanites.

Turning historic buildings into modern living spaces is always a challenge, namely because of the approvals required by state historic preservation agencies and the U.S. National Park Service. Preservation groups focus on windows, yet there is no cookie cutter approach to finding the perfect window that complements the new space, while simultaneously pays homage to the building’s past.

Eitel, for example, did not have any of its original windows, and Village Green was not able to get its hands on the original construction documents. Fortunately, the firm’s architect located design studies which detail the project’s original windows and allowed Village Green to work with St. Louis-based Quaker Windows & Doors to fabricate custom windows for Eitel.

The end result is worth the work to find replacement windows, says Shawn Zimny, Village Green’s vice president of development. “Historic buildings have a panache that everyone loves.”
