Wonky staircase takes lead from Serpentine pavilion

A huge spiral staircase made of scaffolding and wooden slats will be at the centre of an art exhibition opening today.

The installation, by Graham Hudson, is part of Anita and Poju Zabludowicz's Material Presence collection and resembles a prototype of the Serpentine Gallery's pavilion designed by architect Frank Gehry.

It will be unveiled in the central hall of 176, a new gallery in Prince of Wales Road, Camden - converted from an old Methodist church.

The sculpture, which is called On Off, incorporates light bulbs, record players and motion sensors to encourage visitors to engage with the art work.

A spokesman for the event said: "It is a multisensory interactive experience and is sure to be visually stunning."

The exhibition will open today and tomorrow from 11am until 3pm and on Saturday and Sunday from 11am until 6pm. Admission is free. For more information visit the website: www.projectspace176.com
