★ Treasure House Fair

01Why it matters

London's June had a serious art and antiques fair for thirteen years and then, in early 2023, abruptly did not. Treasure House filled the gap in a single season and kept the historical trade's summer date alive at a moment when several other fairs in the same field were closing.

Our reading is that it now functions as the historical trade's counterpart to Frieze week: the June fair for people who buy across periods, positioned in the middle of the British summer season. Its scale is modest and its ambitions appropriately local, and that focus is why it worked when a larger predecessor did not.

02The week around it

Late June in London is the busiest stretch of the British summer season, and the fair sits inside it rather than dominating it. London Art Week, the Mayfair and St James's dealers' coordinated selling exhibitions of Old Masters, sculpture and works on paper, runs in the same fortnight and is free to walk into; the summer sales at Christie's, Sotheby's and Bonhams fall in the same weeks with free public previews. Beyond the trade, the diary is crowded: Royal Ascot in mid-June, Wimbledon at the end of the month, Henley at the start of July. Chelsea itself is quiet and residential, and central hotel rates are at their summer peak though the fair creates almost no additional pressure.

03When to arrive

The Wednesday preview if you have an invitation; otherwise any of the public days, of which the first two are busiest for the trade and the weekend is more general. The fair takes two to three hours. Build the day around it: London Art Week's galleries in the morning, the fair in the afternoon.

04Where to stay

Chelsea and Belgravia are the obvious neighbourhoods and put the fair within a short walk or a five-minute taxi; the Cadogan and the Berkeley are the landmark addresses. South Kensington adds the museums and is ten minutes away. Mayfair and St James's are the right base for anyone whose week is really about London Art Week and the auction houses, twenty minutes by taxi.

05Access and hospitality

The fair sells tickets for the public days through its own website and at the entrance, and the organizer publishes prices each year; they are not reproduced here. The Wednesday preview is by invitation, issued by the fair and by exhibiting dealers to their own clients. Vetting by independent experts applies to every object shown, which is the fair's central claim and worth understanding before buying. London Art Week's selling exhibitions and the auction house previews in the same fortnight are free and open to anyone.

06Where the social activity happens

The pavilion has its own restaurant and champagne bar and, because the fair is small, these function as the meeting rooms for the whole event. Outside, Chelsea's geography takes over: the King's Road and Sloane Square, the pubs and restaurants along the Embankment and around Royal Hospital Road, and the Chelsea Physic Garden a few minutes east. The trade's evenings happen in Mayfair and St James's rather than in Chelsea, around the London Art Week openings.

08Practicalities

09History

Masterpiece London ran on the same Royal Hospital Chelsea site from 2010 and became the principal British summer fair for art, antiques and design. Its owner cancelled the 2023 edition and closed the fair, citing rising costs and a weakened exhibitor base. Harry Van der Hoorn and Thomas Woodham-Smith, both involved in Masterpiece's organization, launched the Treasure House Fair on the same grounds and in the same slot within months. The 2026 edition was its fourth.

10Who is there

British and European collectors of antiques, jewellery, silver, furniture and pictures; the London historical trade in full; interior designers and decorators, who are a larger part of this fair's audience than of most; museum curators from British institutions; and a Chelsea and Belgravia local audience for whom the fair is a familiar part of the summer. The mix is older and more decorative-arts focused than the autumn fairs.
