Her best known works include Stone Drawing for St John's College, Oxford, completed in 2019, and Henslow's Walk at Sainsbury Laboratory, University of Cambridge, winner of the Stirling Prize 2012.

A series of high profile commissions followed including Waterwindow, part of the Phoenix Initiative (a Millennium Urban Regeneration Scheme), a waterfall and window sited at the change in levels in Priory Place, Coventry.

[23] The splash from the waterfall is continuously recorded in the build-up of green patina on copper panels, evolving and changing over time to form a water-sensitive drawing.

In 2009 Heron was commissioned to make a new work entitled Henslow’s Walk for the Sainsbury Laboratory, University of Cambridge with Stanton Williams, winner of the Stirling Prize in 2012.

[1] The work comprises four double images carved in shallow relief on a 22m length interior wall; inspired by John Stevens Henslow and his collations of native plants.

"Employing her favoured medium of drawings in shallow relief, Heron has created a backdrop to the Laboratory’s lecture theatre intricately carved into the yellow French limestone, which forms part of the fabric of the building.

"[25] Heron collaborated with Bennetts Associates between 2012-15 to make Travertine Frieze, a shallow carving in negative relief of floor to ceiling drawn lines.
