More market: The Haupt Antiek Market compound is compounding. The antique, vintage and decor monthly occasional sale has purchased and will open a third building on Robert Trail in Rosemount Thursday. Co-owner Deb Haupt said the "Guest Haus," a 1920s residence, has 2,000 square feet, almost doubling the venue for the monthly market, which also operates from a former residence and carriage house. With that space comes more stuff; Haupt said she will add six to eight dealers to the existing roster of 18. Also making a debut at the Dec. 6-9 sale will be finds from Haupt's recent tour of flea markets in France, Belgium and Holland. 14690 S. Robert Trail; 651-329-3871.
