The two stacked, factory-built modular homes of Sparrow Condominiums were created in 2007 as an affordable housing prototype commissioned by developer Unico Properties, designed by Mithun and Hybrid Architecture, and displayed at Rainier Square in Seattle. In 2009, Bainbridge Island resident and retired CEO of Unico Dale Sperling donates them to HRB. They are stored at the city’s public works site before being transported to HRB’s primary rental neighborhood on Knechtel Way. Sperling means sparrow in German.
