They're not wonder walls! Noel Gallagher wins permission for major overhaul of his 'rundown' new £11.5m London home that is plagued with structural movement, leaking roof and rising damp

Noel Gallagher is facing a lengthy period of construction work at his new £11.5million mansion after being given the green light by council chiefs to overhaul the rundown Grade II-listed building.

The historic London property, built in the mid-19th century, needs a complete refit as it’s plagued with significant issues such as structural movement, a leaking roof and rising damp.

In the past, the stunning five-level home had been extensively altered and split into flats before a previous owner converted it back into one single home again.

This has caused Noel a major headache, although it’s not known if he knew this before or after the purchase.

According to docs submitted with 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’.

The Oasis guitarist has been forced to tear out expensive fixtures and fittings from all the rooms – including seven bedrooms – which are now empty shells with no luxury wallpaper or flooring.

The 59-year-old’s home changes will include a new gym, sauna, cinema room and basement bar.

The back extension’s roof and doors need changing too.

Noel Gallagher has received planning approval to carry out a major renovation of his £11.5 million Grade II-listed London mansion

He also wants an interlinking building to be converted into a one-bed guest suite, perhaps for when his brother Liam stays.

The planning officer John Wilman is impressed with Noel’s improvements, writing in his report recommending approval of the proposals that they ‘would not harm the special interest and significance of the buildings and would offer a modest enhancement in terms of fenestration changes, while offering some enhancement to both buildings’ external appearance and character.’

Approval was given by the council with very few conditions, considering the magnitude of the renovations after Noel’s team produced plans confirming that they will be sustainable and are necessary repairs rather than wholesale changes to the historic building.

The decision letter requires that ‘all new work to the outside of the building must match existing original work in terms of the choice of materials, method of construction and finished appearance’ and all building work stick rigidly to 8am to 6pm, Monday to Friday, and 9am to 1pm on Saturday.

Submitted docs state that as much of the demolition and excavation material will be recycled.

'Construction waste will be minimised through careful deconstruction rather than demolition, allowing materials that cannot be reused on site to be separated and recycled where possible,’ say submitted docs.

'The careful repair, reuse and upgrading of the existing building fabric represents the most sustainable approach to development, extending the life of the historic structure while reducing embodied carbon and construction waste.

'Improvements to environmental performance will be achieved through conservation-style slimline double-glazed windows, improved draught-proofing, roof insulation, efficient building services and the use of durable, natural materials wherever possible.'

The renovation will involve stripping out the interiors and repairing the building, alongside adding modern features such as a gym, sauna, cinema room and basement bar. Pictured is the interior of the property

A report drafted by his architects added that they didn’t want to rip the house up but that the improvements were necessary.

It adds: 'The proposed works are limited to the repair, maintenance and like-for-like renewal of defective building fabric, together with the removal of later non-original internal elements and renewal of services using existing routes.

'They do not involve the alteration of features of special architectural or historic interest, nor any change to the character or appearance of the listed building.

'These works are undertaken on a like-for-like basis, using matching traditional materials and techniques, and are directed solely to remedying deterioration and ensuring the continued weather-tightness and long-term maintenance of the building.

'Internally, original features including doors, architraves, panelling, cornices and other historic detailing are to be retained and refurbished. Works are limited to the removal of later, non-original fabric of no heritage significance.’

Noel's brother, Liam, bought former England footballer Tony Adams’ Cotswolds mansion earlier this year for £4million, securing it for £250,000 below the £4.2million asking price.

The eight-bedroom property, called Dockem House, sits on five acres near Cirencester and includes a swimming pool, tennis courts, stables and a separate two-bedroom cottage. 

Oasis recently released a documentary, Oasis: Don’t Look Back in Anger, which follows brothers Liam and Noel Gallagher through their bitter feud, reconciliation and 2025 comeback tour.
