Caroline Feiffer is a brand designer from Denmark that she recently worked with Frederik Bille Brahe on Atelier September and Apollo Bar. She lives in a beautiful house on the top floor of a 1737 townhouse on the Frederiksholms Kanal in old Copenhagen that she renovated with her husband. The flat is located in a narrow and a 860-square-foot sloped attic space. The couple replaced the floors with bleached pine, painted the walls and beams tonal white, remodeled the kitchen, and sectioned off rooms with Danish, French, and Italian antiques.
