After two decades at its former Wirt Road location, Joyce Horn Antiques has relocated to the burgeoning design area on Old Katy Road, just opposite Houston Design Center. The venerable 30-year-old firm — run by its namesake, Horn’s daughter Reid Nelson and manager Chris Prewitt — gained fame for its ample selection of French antiques with a smattering of European pieces culled from Scandinavia, Germany, Spain and Italy. Every other month or so, a new shipment arrives to refill the sprawling 11,000-square-foot space, which is broken into smaller vignettes with decorative painting by artist Leslie Sinclair and even a charming mezzanine with a spiral iron Louis XIV staircase from a house in Paris, which was sourced eons ago on a buying trip to France. Days before the location’s debut last month we spied a Louis XIII 19th-century enfilade, a Gustavian 18th-century settee with strong bones (only in need of great fabric) and a 19th-century painted bombe commode — one of many painted pieces Horn and Nelson seek out for their clientele. And did we mention the mirrors? Horn teasingly admits she was known for years as the armoire queen, and now she’s none other than the mirror queen — and no wonder, we can’t recall a better selection (particularly loads of those crusty gilded Louis Philippe sort) anywhere in town. Although shopped in large measure by the design trade, Joyce Horn Antiques welcomes everyone, regardless of decorative acumen, Monday to Friday (Saturday by appointment). 7065 Old Katy Road, 713.688.0507; joycehornantiques.com.
