Stand on the platform at Edgware Road tube station (the Circle Line branch that is, not the Bakerloo line), face south, and you can hardly fail to notice Wrapper – Jacqueline Poncelet’s latest work, which literally wraps the building above in 1,500 square metres of vitreous enamel. There’s much to like about this striking work – one aspect I find particularly fascinating is the way in which Poncelet uses patterns and colours to tell a story, a device often found in her work.

As regular Tube travellers will soon guess, the colours employed in Wrapper reflect those used for various lines on the Tube map, in a nice hat tip to the building’s use. Poncelet’s research into the local area led to the inclusion of numerous references to local history, places, architecture, transport, waterways and people in the work’s patterns. Closer inspection reveals the leaves of Regents Park, water patterns that suggest the Tyburn stream flowing underground and Moorish tiles reflecting nearby Edgware Road.

Some of the best views of Wrapper are gained from outside the station in Chapel Street. Both the variety of Wrapper’s patterns and the differing contours it follows around the building means that different stories and different views of the work are revealed depending on where the viewer stands. In this way, Poncelet’s design reflects the way in which the building is generally viewed in parts rather than in its entirety.

Poncelet started her artistic career as a ceramicist but has since branched out. Wrapper’s abstract patterns were actually screenprinted onto the enamel surface. To give some idea of the massive scale of the work, over 700 enamel panels were used across approximately 1,500 square metres, making Wrapper not only Poncelet’s largest work but Europe’s biggest vitreous enamel artwork.

Thanks to Joanna Moncrieff, City of Westminster Tour Guide and Westminster Walking blogger, who tipped me off about Wrapper after seeing it on one of her walks.
