HISTORIANS say plans to upgrade an historic hall linked to the Brontës will “tarnish the purity” of the building. Gomersal’s Red House, formerly a museum, is to get a new lease of life as a short-term holiday destination and intimate wedding venue. Kirklees Council says the scheme will safeguard the site for the future. But opposition is growing to scheme from historians who believe “comprehensive refurbishment and some sympathetic remodelling” earmarked for the house could mean intrusive modern additions. They are now marshalling support to fight what they suspect will be unwelcome improvements. And they have threatened to mount a legal challenge.
