Hough End was originally given to Manchester City Council by Lord Egerton and a Restrictive Covenant placed on the Title of the land “not to use or permit to be used this area for any purpose other than as an open space and recreational ground for the free use of the public”. This is especially relevant as by fencing the area, it’s likely you will be charging for use and reducing the public open space. As the Covenant is in favour of the public ie. free use, any breach of this Covenant should presumably compensate “the public” for loss of free rights over the area.
On this basis the proposal is unacceptable and should be refused.
