[2][3] After a period of closure to undergo a significant renovation, the gallery reopened in 2021 with expanded exhibition space and facilities.

[4] Designed by Edinburgh-based Reiach and Hall,[6] the revamp included overhauling the existing gallery spaces, as well creating a new exhibition space in a nearby former fruit and vegetable warehouse (later the Electric Circus nightclub), effectively doubling the footprint of the gallery.

[7] The refurbishment also created a new space dedicated to classes and workshops, while the existing bookshop and cafe were expanded.

Several artists have been prominent supporters of the project, even as the COVID-19 pandemic put building on hold and pushed up costs: Martin Creed donated the proceeds of a neon work that sold for more than £50,000; Callum Innes helped choose the project architect; and Tania Kovats designed a £15,000 ceramic drinking fountain for the building, intended for visitors to fill up their water bottles.

[4][9][10][11] Exhibitions have included international artists such as Janet Cardiff and George Bures Miller, Trenton Doyle Hancock, Cai Guo-Qiang, Alex Hartley and Roman Signer, as well as Scottish artists Callum Innes, Christine Borland, Nathan Coley, Louise Hopkins, Lucy Skaer and Emma Hart.
