Joseph Bromfield (1744–1824) was a notable English plasterer and architect working in the West Midlands and in Central and Northern Wales in the late Georgian period.

[2] The father, Robert Bromfield, appears to have been associated with the Shrewsbury architect Thomas Farnolls Pritchard whose most important work was the designs for the Iron Bridge at Ironbridge.

[4] He now undertook some commissions for fairly major country houses, such as Rhug, Caerynwch and Nanhoron; rectories, including Newtown and Llandyssil in Montgomeryshire, and the workhouses at Morda outside Oswestry and Forden near Montgomery.

Bromfield was a pioneer of the early use of cast ironwork in domestic buildings, probably sourced from William Hazeldine's foundries in Coleham, Shrewsbury and Plas Kynaston near the Pontcysyllte aqueduct at Chirk.

The use of the Greek Revival style is comparatively rare and Pevsner and Lang point out that the earliest example of it is James "Athenian" Stuart's Doric temple at Hagley Park.
