Enclosure, a newly commissioned film and installation by Somerset House Studios artist Jenkin van Zyl, opened this week in the Lancaster Rooms at Somerset House. The project is van Zyl’s first major London exhibition and imagines a world in which technological systems have continued developing long after the ideas that once justified them have begun to fall apart.

June’s London Gallery Weekend has, in recent years, quietly stopped being a single weekend. Several of the galleries that opened exhibitions to coincide with the event’s private views on 4–7 June kept those same shows running deep into September — Sadie Coles HQ’s presentations by John Currin, Helen Marten and Kiik Amor among them, with both the Currin exhibition at 17 Savile Row and Marten’s presentation at The Shop on Kingly Street scheduled to run until 12 September.
