Noel Gallagher's £11.5million London home plagued by 'significant structural movement', leaky roof and rising damp just months after buying it

Noel Gallagher's new £11.5million mansion is in need of repairs already - as the Oasis guitarist bids for permission to fix problems such as a leaky roof and rising damp.The Oasis guitarist once claimed DIY SOS Nick Knowles' singing sounded like 'he's having a stroke' - but might now appreciate his building acumen, with works needed for the musician's new home.His Grade II-listed property in north London needs a refit due to issues including 'structural movement', according to council planning documents.The five-level home Gallagher bought last year was previously extensively altered and split into flats before an ex-owner converted it into one single home.According to documents now submitted to Westminster Council, there is 'significant structural movement', 'water ingress from roof level', 'rising damp at lower levels', 'deterioration of roof covering' and 'previous unsympathetic alterations'.Gallagher, 59, has had to tear out fixtures and fittings from all rooms - including seven bedrooms - which are now empty shells with no luxury wallpaper or flooring.His proposed home changes would include a new gym, sauna, cinema room and basement bar.He has been given the green light by council planners for some of the renovations replacing or repairing issues like-for-like.
