Recent work is a response to the death of the image, the loss of the visible world and the post-representational turn brought about by digital technologies, Iremonger's abstract works Horizons seek new strategies for painting in the 21st century. Based in Kinsale, Co. Cork, Ireland. Early work consisted of oil painting embedded in the modernist tradition with epic implications. Later works attempted a kind of entanglement with the world through site-specific installations that explored representation.

A return to painting since 2014 has focused on the adaptation of found images creating complex abstract paintings and drawings where signifiers are hidden in a sea of post-representational visual noise. A second series uses Venn Diagrams to guide a self-directed systematic approach to making paintings. Text-based work based on notebooks collected over thirty years explores a search for meaning through process, texts are reframed and reorganised in the style of an epic non-rhyming stream-of-consciousness prose poem.
