Ever since visiting the exhibition space, a few years ago, I don’t think I have ever missed one single show. It is one of the best exhibition spaces for contemporary art in London, in my opinion.

Excellent gallery. It has big rooms which often feature large pieces and admission is free.

G.F. Smith's permanent showroom, in Central London. Visits are by appointments only — But I would definitely recommend making the visit. All of their stocks are beautifully archived, along with example publications, and a rotating series of paper installations in both the window & basement, courtesy of Made Thought.
