(Radio Iowa) – Four homes in central Iowa that serve as sterling examples of mid-century modern architecture and interior design will be open for tours during a special fundraising event this weekend. Laura Porter, executive director of the Iowa Architectural Foundation, says “Midwest Modern, a Mid-Century Modern Home Tour,” will showcase these four beautiful homes in the Des Moines metro area, all built between 1952 and 1970.

The homes spotlight the iconic lines and materials of the period, she says, including one house with three angled wings and a rounded glass skylight that encircles its attic chimney. The mid-century modern style, Porter says, has a very devoted following.

The home tour event has been held since 2013. Porter says the tours provide inside views of excellent architectural examples of the era, but they also exhibit how to bring mid-century styles to homes of every decade.

She says mid-century homes have not only remained popular for their designs, but they also represent a time of innovation and creativity in architecture. Part of the proceeds from the event will benefit the Iowa Architectural Foundation’s educational programs for children and adults. Two of this year’s featured homes are in Des Moines, with one each in Clive and Windsor Heights. The Sunday tour is sold out.
