Is your yard full of demanding, design-conscious finches? Are you in need of a very cool, artist- or architect-designed birdhouse? This one, made of wood and aluminum by architect Sig Froelich, is one of 50 to be auctioned off June 6 from 6 to 10 p.m. at artist Wesley Kimler’s studio, 2046 W. Carroll Ave. Tickets, which cover an open bar and appetizers, are $20 in advance through the Friends of Pritzker. Proceeds will go toward the building costs for a preschool and kindergarten playground at the Pritzker School. Your local feathered friends are guaranteed to sleep better.
