Antique Co-Op and Auction House, 730 Eastern Ave, Malden, MA 02148, US

The Barn at 17 is 10,ooo square feet of cherry-picked antiques. The stock spans from late-18th century to mid-1950s pieces, and the store is tucked into a little nest of creatively fueled businesses on Murdock Street. The showroom is both enormous and delightfully rustic - it's an actual renovated carriage barn - the staff is extremely knowledgeable and the antiques are of unsurpassed quality. The Barn at 17 was voted 'Best of Boston, 2010' in Boston Magazine. A sister company, Blackstone Furniture Restorers, shares the same property.
