Harry Styles plans 100 speakers at his under-renovation London home - including in the toilets

Harry Styles is turning his London home into a giant sound system – and installing dozens of secret speakers, including in the toilets.

The singer has applied for planning permission for the top-of-the-range home audio throughout his Grade II-listed London properties, which he's currently merging into one luxury mansion.

The system would use Sonance Invisible speakers, which are plastered into ceilings and walls so they can't be seen, along with subwoofers for extra bass.

There would be approximately 100 units across five floors.

In a heritage statement, the 32-year-old's planning consultants say the speakers would be installed behind the final plaster finish and be completely invisible.

Because the house is a listed building, the council must approve even these discreet speakers.

The document states: 'The proposed development comprises the installation of speakers within the plasterboard ceilings and walls across all floors, in locations as shown on the proposed plans.

'The speakers are to be installed behind the final plaster finish and will therefore be completely invisible.'

It goes on to say there would be 'limited impact on the historic fabric of the existing building'.

With it concluding: 'Overall, the proposed works would constitute a minor and discreet intervention.

'The concealed nature of the speakers, together with their installation predominantly within areas already subject to approved works, would ensure that there would be no material impact on the character, appearance of the building and there will be a negligible impact on its historic fabric.'

The application is the latest chapter in Styles' long-running project to restore an 18th-century mansion that had been split into two homes in the 1950s.

It's expected to take two years and cost millions after winning approval in April 2025.

The second-floor master bedroom, lounge, bathroom and three dressing rooms would have 23 ceiling speakers fitted. This includes the suite's two toilets, which get their own speaker, and the vestibule another two.

The basement cinema is set to be kitted out with speakers. On the lower ground floor, they'd be fitted in the gym, changing area, wet area and lounge.

On the ground floor, the TV room, gallery, dining room, drawing room and both kitchens would be wired for sound, while on the first floor the bedrooms and bathrooms are included.

Harry has reportedly spent around £18million purchasing the properties, including an adjoining house intended to serve as a gatehouse and a fourth property on the same street for guests.

He bought the first house in 2019 for £8.8million, and the wider renovation project is expected to be completed by the end of 2027.

Plans for the mansion also include an art gallery and an indoor patio.

The renovation also includes several measures to protect local wildlife, with plans for bat boxes and bug hotels. 

Harry's team have held meetings with local residents and distributed leaflets to keep neighbours informed about potential disruption caused by construction traffic and noise.

Measures were also agreed to minimise noise, including installing acoustic enclosures around machinery, using electric equipment where possible and ensuring vehicle engines are switched off when stationary.

Harry's neighbours have reportedly raised concerns that his mansion could block sunlight from their homes, potentially leaving them fighting for their 'right to light'. Some residents have described the property as 'overbearing' and complained about the ongoing disruption caused by construction work.
