Curled up on the couch in the traditionally decorated TV room of the Alpha Gamma Delta house at University of Kentucky in 2002, freshman Liz Toombs watched an episode of the reality show “Trading Spaces” that featured a sorority house redesign. “I didn’t think it was real, just that it was a made-for-TV moment,” she said. Years later, Mrs. Toombs, who launched her Lexington, Ky.-based interior design firm, PDR Interiors, in 2009, was approached by a Greek organization that needed help updating its 1970s home at the University of Kentucky. She took the project, and has since gone all-in on this niche design space, even adapting her company logo to a Greek key. Sorority design is now about 90% of her business, she said.
