HAMDEN — Described by town economic-development czar Dale Kroop as “the largest redevelopment project in southern Hamden in 25-plus years,” Highwood Square officially opened its doors with a June 3 ribbon-cutting. The facility, located at 953 Dixwell Avenue (across the street from the Keefe Center), is mixed-use artist housing and commercial. The commercial component may be “pedestrian/retail services,” according to Kroop, or arts-related, such as gallery space.
