A year in Rookery Gardens: new paintings by Jonathan Cowell with ceramics by Claire Griffiths

6-15 February 2026

Paintings of urban green space + coastal hand-coiled ceramics.

Jonathan Cowell spent 2025 in Rookery Gardens at Streatham Common, producing paintings for every month of the year. Working both outdoors and in the studio, he painted in oil on canvas and board in response to the changing light and nature of the seasons, alongside later, studio-based works developed from his many drawings.

“These studio paintings were like meditations on the experience of being in the place, I spent so much time there over the course of the year.” - Jonathan Cowell.

Jonathan’s paintings will be accompanied by the hand-coiled sculptural ceramics of Claire Griffiths. Infused with sea glass and coastal hues, Claire’s ceramics capture the interplay of light, earth, and water - a fragile balance reflecting both life’s beauty and uncertainty.

“I am delighted to be showing my work alongside Jonathan Cowell, whom I met for the first time many years ago and whose paintings I have always admired greatly for their subject matter and use of colour.” - Claire Griffiths.
