It was put on hold once again while "minor contractual issues" were being resolved.
Now, the application has been held up over a need to "undertake further surveys and design work" in relation to repairing and converting the Grade II* listed site.

They added: "[Norwich River] is excited about the proposed development, and was grateful for the strong turnout at the public exhibition held last year, and the positive comments received from members of the public.
"However, prior to finalising the application proposals, it has transpired that there has been a need to undertake further surveys and design work in relation to the proposals to repair and convert the listed buildings, which are in a poor condition.
"These proposals are being finalised at the moment, and [Norwich River] hope to be in a position to submit an application soon."
