North Wales Housing Association had purchased a guest house in Llandudno with the intention of providing a facility to allow vulnerable adults to holiday in the area, thus giving them a break from their carers. However restrictions on the use of the building prevented it from being used for any other purpose than a guesthouse. We prepared a detailed case which demonstrated that the proposed use of the building to provide ‘breaks’ for vulnerable adults, with some supervisions by staff, did not constitute a change from the existing use of the building as a guesthouse. Following lengthy discussions with the Council a Certificate of Lawful use was granted confirming this and the Housing Association was able to develop this vital facility.
