One small business in Greater Des Moines will win an office makeover thanks to a contest held by office design company Turnstone. The Culture@Work in the Heartland contest will give $20,000 office space makeovers to small businesses of fewer than 100 employees in five Midwest cities, including Des Moines. To apply, companies must show Turnstone how a better space could improve their company culture. Applications are due by Feb. 10, and more information on the contest and process can be found here. In a similar contest in May, Veel Hoeden, a business incubator in Pella, won $25,000 for an office makeover.
