A non-profit group is seeking to restore a 91-year-old home designed by Frank Lloyd Wright for low-income families in Milwaukee.

The single-family home is one of four duplexes and two cottages from what the architect called "American System-Built Homes" — a series of prefabricated dwellings that Wright hoped would become a national line. Wright, one of the world's most prominent and respected architects, believed low-income families deserved high-quality architecture.

The Frank Lloyd Wright Wisconsin group is attempting to restore one of the 850-square-foot homes to its original 1916 condition.

The group hopes the project will inspire the renovation of the remaining homes, as well as prompt architects to design more affordable housing.

Wright historian Jack Holzhueter said the homes are a shining example of Wright's passion for providing affordable housing for low-income families.

"It's early relatively in his career, 1916," Holzhueter told the Associated Press. "It's a very large group of buildings. No other cluster of Wright buildings begins to resemble this one, in proximity, density, etcetera."

Frank Lloyd Wright Wisconsin hopes the site will facilitate education programs.

"We feel that it's important that we restore them as well and open them again leading into the educational component to maybe have people design homes today just like Wright did almost 100 years ago," said Denise Hice, the group's president.

Frank Lloyd Wright Wisconsin bought the single-family home in 2004 for $130,000 US from an owner who lived there for about 40 years. The homes sold originally for $3,500 to $4,500.

The organization also bought one of the duplexes in 2005 for $142,000.

Mike Lilek, the group's treasurer, expects the restoration project to take more than a year to complete.

The project's budget is estimated at $379,369, Lilek said. The group has so far raised $298,500.

"We're going to try and turn these back to owner-occupied buildings," he said.

"I don't know if me or you would move into a building in its 1916 condition."
