Designed in 1958, the cottage is balanced on the edge of a secluded promontory that plunges down to Mirror Lake in one of Wisconsin's most popular state parks near the Wisconsin Dells, . The building possesses a monumentality that is surprising in so small a structure. The exterior and interior walls and huge central fireplace are horizontally-layered local sandstone. Floor and terraces are flagstone. You can actually spend a weekend or a week in a Frank Lloyd Wright cottage. This 900-square foot building is available for vacation rental. The great soaring roof, which seems to hang in space without support, frames the principal views to the west and south, and opens the interior to the surrounding trees, the lake view, and to light and shadow.

She decided to investigate, and the rest is history.  It turned out the cottage, known as the Seth Peterson Cottage, was one of the last commissions of famed architect Frank Lloyd Wright. Laatsch launched a grass-roots campaign to have the cottage restored, and after a lot of sweat and tears, the restoration was finished for Wright's 125th birthday anniversary in June 1992.   Laatsch died last August (2002). Mount Horeb artist Jeff Hagen - best known lately for his lively books on Wisconsin fish fries - was Laatsch's friend and spoke with her days before her death. "She was a great woman," Hagen said Friday. The artist had thought about writing some kind of obituary but decided to try something that would be more lasting. He wound up doing a watercolor painting, "Audrey's Star," of the Peterson cabin, and now a limited edition print of the painting has just been made available, with proceeds going to Laatsch's memorial fund.
