The problem with BRNC is that it is a Grade 2* listed building and the insides can't be touched.....not many hotels would want 200+ 8'x10' rooms!!
As above, not true. The planners/conservation officers would seek to maintain the facade and key interior features/spaces (Chapel, Quarterdeck etc) but all the accommodation floors would be fair game for changes.
Admiral of the Fleet Sir Caspar John must be turning in his grave - no way would CJH survive a developer's demolition hammer.
