Seven years ago, new-in-Newtown Meg Newell met longer-time residents Christine Edmonds and Rebecca Bancroft at “porch fest,” the borough’s every-warm-Friday-night outdoor cocktail party. The trio instantly bonded over their shared love for antique, vintage and modern design. Soon thereafter, they came up with the idea for Trove, a boutique firm that restores, repurposes and generally revives marvelous old furnishings and accessories to sell at weekend-long sales in the Newells’ 19th-century carriage house. These days, the company has grown. A lot. Trove has a shop at Cape May’s West End Garage, consults on custom design, and vends at Brooklyn Flea and, as of this month, Ardmore’s Clover Market — spreading the trio’s aesthetic far beyond one Bucks County backyard. Still, nowhere does their easy, elegant style, a blend of today and yesterday, neutrality and drama, polish and patina, showcase better than in Newell’s own center-hall Georgian. “I’m not sure if Trove is an extension of my house, or my house is a product of Trove,” she says.
