The Portman Estate, a private landowner in Marylebone, London, was established in 1532 when Sir William Portman, Lord Chief Justice to King Henry VIII, leased 270 acres of the Manor of Lileston (Lisson). Owned by the Portman family for centuries, the estate is currently managed by the Portman Estate Company. The Portman Estate comprises 110 acres of Marylebone in London’s West End, including frontages to Oxford Street and Baker Street. It covers 69 streets, 650 buildings and four garden squares all housing over 700 directly managed residential units, 290 office units, 150 shops and restaurants, 27 hotels and seven pubs. The Portman Estate is committed to excellence in customer service and aims to be the destination of choice for residents, businesses and visitors, where the buildings exceed market demand and the environment is distinctive, varied and vibrant. Since 2002, the Estate has directly invested an average of £20 million per year throughout Marylebone. This has included the regeneration of its independent retail streets, Seymour Place, New Quebec Street and Chiltern Street, and the introduction of new extensively renovated hotels The Zetter Townhouse and Z at Gloucester Place. Over the next ten years, an estimated £250 million will be reinvested Estate-wide to ensure long term growth and create attractive, vibrant spaces for the Marylebone community to enjoy. Projects currently under construction on the Estate include the redevelopment of 1 – 4 Marble Arch, plus joint ventures with Native Land at Regent House on Edgware Road and the landmark mixed use development with Almacantar at Marble Arch Place.
