Christine Orlanes' affordable home design took top honors at the Polk County Housing Trust Fund's Design Challenge for Affordable Housing. Orlanes, a senior at Ankeny High School, received a $2,000 scholarship from the Home Builders Association of Greater Des Moines. Runners-up Cole Schenk, who also attends Ankeny High School, won a $500 prize provided by the Polk County Housing Trust Fund and Riley Dunn, who attends Des Moines Central Campus and Martensdale-St. Mary's High School, won $500 provided by ASK Studio, a Des Moines architectural firm. Forty students from five Greater Des Moines high schools were given the fictional background of who would be living in the home - their hobbies, interests and special needs - where the vacant lot was located, maximum square footage and limitations on costs. The event wrapped up Affordable Housing Week activities.
