Roger Hiorns: Seizure

In 2008 Roger Hiorns transformed an empty council flat in Southwark, London into Seizure, a sparkling blue world of copper sulphate crystals. The work was created using 75,000 litres of liquid copper sulphate, which was pumped into the former dwelling to create a strangely beautiful and somewhat menacing crystalline growth on the walls, floor, ceiling and even the bath of the abandoned flat.

Faced with demolition of the social-housing block in early 2011, Seizure was acquired by the Arts Council Collection. The work, weighing over 31 tonnes, was successfully extracted from the property following meticulous planning, which saw one wall of the flat removed before the whole structure was pulled out of the building using hydraulic jacks and craned onto the back of a truck. Seizure was then transported to YSP where it is presented within an award-winning concrete structure, commissioned from Adam Khan Architects.

Opening Times

In order to conserve the artwork and extend it's lifespan, access to Seizure is by pre-booked time slot only - book here.

Capacity is limited and we recommend booking prior to your visit to avoid disappointment. Bookings includes your admission to YSP and there is no additional charge to visit Seizure.

Pre-booked appointments are available during weekends, Bank Holidays and Wakefield school holidays only. Please note that these opening hours may be reduced in cases of extreme weather, which affect the work. We will contact all bookers in the event of unexpected closures.


Due to the nature of the work, Seizure is not wheelchair accessible. The base of the work is uneven and made up of copper sulphate crystals, with access via steps.
