Bonnie Barr shows off the blueprints to a Wind Point home on June 20. WIND POINT — Kali Behlmer grinned from ear to ear. “I can’t believe she just does this,” she said, walking alongside her mother, Bonnie Barr, as they approached a stranger’s home in Wind Point. “It’s really cool.” They rang the doorbell. An unexpected visit Barr is on a quest like no other. She’s the daughter of Bill Barr — the architect behind Barr Construction Company — who built 400 homes in Racine and Kenosha counties from the 1940s to 1970s. Recently, the Barrs found a slew of Bill’s blueprints and drafts of those 400 homes. Bonnie, often recruiting different members of the family, set out starting last August to deliver the renderings to their respective homeowners.
