Nicholas Ponsonby Haslam (born 27 September 1939) is an English interior designer and socialite, and founder of the London-based interior design firm, NH Studio Ltd.
Haslam was born at Great Hundridge Manor, Amersham, Buckinghamshire, the third son of diplomat William Heywood Haslam (1889–1981) and his wife, the former Diamond Louise Constance Ponsonby, known as Diana, who was a granddaughter of the 7th Earl of Bessborough, a goddaughter of Queen Victoria, and the former wife of Dr. Henry E. Marks, an American physician. Haslam's brothers are Ralph Michael Haslam (born 1931) and William John Heywood Haslam (born 1933). He also had a half-sister, Diana Marks, known as Anne (1925–1987), who in 1949 married John Hilder Loeb, son of a founding partner of the Brillo Manufacturing Corporation.
Haslam was educated at a private school and then at Eton College.
In 1966, Haslam and his lover at the time, American banking heir James Davison, bought Black Canyon Ranch, near Phoenix, Arizona for breeding and showing Arabian horses. From 1970 he combined breeding show horses, working in Los Angeles as a photographer and designing rooms and parties for clients such as Natalie Wood.
Haslam broke up with Davison and returned to London in 1972, where he was soon asked to design and decorate a townhouse for Alexander Hesketh. In the early 1980s, Haslam owned and operated the Nicholas Haslam Showroom on Holbein Place, London, together with his then-partner, Paolo Moschino. When the pair split in 1995, Haslam took control of NH Design as the interior design side of the business, with Moschino taking ownership of the Nicholas Haslam shop. The two businesses today operate separately.
In 2002 Haslam published a book of his work entitled Sheer Opulence and is working on a second book on design. His autobiography Redeeming Features was published in 2009; in it he mentions his affairs with numerous individuals, including architect Philip Johnson, photographer Antony Armstrong-Jones, art dealer Cavan O'Brien, and artist Michael Wishart. He is a frequent columnist for The London Evening Standard and The Sunday Telegraph magazines. Besides frequently writing reviews for The World of Interiors and The Spectator, Haslam wrote a gossip column for Ritz Newspaper under the pseudonym 'Paul Parsons', and has been a contributing editor of British Vogue and Tatler for many years. In December 2010, Haslam started blogging for The Telegraph.
Before launching her own retail chain, the designer Cath Kidston worked for Haslam.
In 2011 Haslam designed a set for the play "As I like it" by Amanda Eliasch and also worked on her house in Cheyne Walk.
In March 2013, Haslam published a book entitled "Nicky Halslam's Folly de Grandeur: Romance and revival in an English country house", which reveals the history and design behind his own home.
In September 2013, with Annabel Astor's luxury furniture company OKA, Haslam launched a collection inspired by Gothick-influenced furniture and accessories from his own house.
In 2016 he was reported to be a supporter of the Conservative Party.
