Hudson was most notable for her architectural models, being particularly attracted to Georgian architecture. Bath's Building of Bath Collection and Bath's Pump Room contain models made by Hudson. A scale model of Dulwich Picture Gallery made by Hudson stands in the gallery's foyer. Hudson made a model of Highgrove, the country house of Charles, Prince of Wales as a present for the Prince and Princess of Wales's wedding in 1981. Hudson was later commissioned by Charles to alter the model when he added a porch to the house. Hudson made models of other private houses, and was reluctant to accept payment for her models.
