[UPDATE1 16 September: a recent walk past the Rockwood showed that the car park had been emptied and gated shut, with the pub still for sale. The entrances are, for the time being, permanently locked and sadly the pub has closed.
If it cannot be sold as a going concern, indications are that it will indeed become another casualty in the ever changing pub landscape. It's always sad to see your own feeling that the place might not be long for this world made reality so soon]
[UPDATE2 25 October: the Rockwood has now been boarded up at both ground and first floor level. Part of the pub's signage has been removed and the For Sale signs have gone, the combination of which suggests that it has been sold, and not for future use as licensed premises.
Perhaps the building will remain, but with the Earl on Nantwich Road having just been demolished after standing idle for some months, the impression is given that the site is about to be levelled and redeveloped. So that 1930s time capsule will be lost. And yes, it will be a crying shame]
[UPDATE3 7 June 2013: the demolition men have moved in and the Rockwood is slowly being flattened. Some of the windows and parts of the roof, particularly chimney stacks, had gone when I looked in. So that time capsule interior will indeed be lost.
What will be built in place of the pub is not known. But it's a big site, and most likely it will be apartments. So that's another one lost]
