The W.A. and A.M. White Co. hat factory at 70 Beaver St. in Danbury, Connecticut, is on the market for $1.5 million. The nearly 78,000-square-foot building, used since 1972 by Kingswood Kitchens for cabinetry, dates back to Danbury’s “Hat City” era. Brokers say redevelopment is likely, with potential for industrial reuse or residential conversion, though no specific plans have been set.
