Downtown DC home-decor store RCKNDY (pronounced “Rock Candy”) tomorrow hosts a discussion and book-signing with architect and home-furnishing designer Lisa Roberts, author of Antiques of the Future. In her book, Roberts recommends more than 200 mass-produced products—such as office furniture, kitchen products, lighting, textiles, and clocks—with such noteworthy designs that they will increase in value over time.

If you haven’t had the chance to stop by RCKNDY, this would be a great opportunity to check out the 1,800-square-foot showroom, which owner David Dennis stocks with pieces by local, national, and international designers including XYdecor, Orange 22, MoxBox, PlushLiving, Blu Dot, Mint, and Mud Australia. The event is free, and complimentary wine will be served.

In 2004, as Oxon Hill Manor was about to complete a major, two-year renovation, a fire broke out in the estate’s east wing and caused severe structural, smoke, and water damage. This summer, the historic Georgian manor finally re-opened to the public. An open house this weekend shows off the restored estate and gives visitors a chance to wander the mansion’s 49 rooms. 

Oxon Hill Manor was built in 1928 for Sumner Welles, undersecretary of State for President Franklin Roosevelt, who was a frequent visitor. Today the mansion—which is owned by the Maryland-National Capital Park and Planning Commission—is a popular site for weddings and other events. Fourteen local caterers will provide snacks and refreshments at this Sunday’s open house, from 1 to 4 PM.

Oxon Hill Manor, 6901 Oxon Hill Road, Oxon Hill; 301-839-7782

Renowned American architect Philip Johnson was strongly influenced by the visual arts, from sculpture to painting. Beginning March 15, the Kreeger Museum hosts the exhibit “Phillip Johnson: Architecture as Art,” which will showcase works of art—including paintings by Jasper Johns and Andy Warhol—that had an impact on Johnson’s work. You can support the upcoming exhibition at a silent auction this week at the Georgetown location of Design Within Reach.

Among the items: this egg-shaped chair by Arne Jacobsen, a butterfly stool designed by Japanese industrial designer Sori Yanagi, and a photograph by architectural photographer Richard Schulman. A closing reception on Saturday, September 29, at 3 PM will reveal the winning bids.

Design Within Reach, 3307 Cady’s Alley, NW; 202-339-0890.
