The English interior designer Nina Campbell may have started her long and illustrious career at Colefax and Fowler, but she has ultimately created an aesthetic that is entirely her own. In the 1960s, nightlife impresario Mark Birley enlisted her to reimagine Annabel’s, his private club in Mayfair, and in the 1970s the two opened Campbell & Birley, a shop on Pimlico Road in Belgravia. Campbell eventually moved to Walton Street in nearby Chelsea, and after more than 50 years in business she continues to design homes all over the world while also running operations for her design studio, shop, and showroom—which, this spring, she is moving back to Pimlico Road. She does all of this with a little help from her children—her son, Max Konig, works with her directly, and her daughter, Rita Konig, is a successful interior designer in her own right. In March, Campbell published her latest book, A House in Maine. Herewith, she shares her key components to the good life. —Ashley Baker
