The 1950s house sat on a beautiful lot in the Buckhead area of Atlanta and had space for expansion, so the couple decided to renovate it and add every longed-for amenity. They called upon Lapelle and architect Yong Pak to create their ultimate empty nest. “The home had a great French sensibility, which we built on,” says Pak. “The steepness of the roofline was correct, but we replaced all the doors and windows, added dormers, and doubled the square footage of the house with two wings off the rear to create a courtyard area for a pool.” Inside, Pak added crown moldings and paneled the library. Additionally, he brought in stair maker Timothy Johnson to design the commanding staircase that defines the entry hall. It now swoops upward past an 18th-century Flemish tapestry and a pair of gilt sconces.
