“Where planning permission had been granted for the erection of a building for storing agricultural products but the building after erection had been used only as a single dwellinghouse, there had been a change of use of the building to that of a dwellinghouse for the purposes of s 171B(2) of the Town and Country Planning Act 1990, and accordingly no enforcement action could be taken after the expiry of a 4–year period.”
