Kate Moss has hit the headlines over plans to renovate her 17th century London home.
The supermodel has applied for planning permission to build a steam room in the basement of the grade II-listed building in Highgate, North London.
She also wants to install eight CCTV cameras, a satellite dish and put in a bath "on an elevated waterproof plinth" in her first-floor dressing room.
Local councillor Maya de Souza said the plans could "impact severely" on Kate's neighbours.
The planning application to Camden council describes the building as "one of six Restoration houses built in a prominent position on the western side of Highgate Hill".
The house has an English Heritage blue plaque commemorating the fact it was home to novelist and playwright JB Priestley.
It was also home to poet Samuel Taylor Coleridge, who lived there for 11 years until his death in 1834.
The application, which was lodged with the council in May, showed Kate had not consulted "neighbours or the local community" before drawing up the plans.
Ms de Souza told the Daily Telegraph the work could disrupt local water supplies.
She said: "My concern is the impact on groundwater flows. This has been known to impact severely on neighbours and can affect water bodies like Highgate ponds, as well as causing construction-related nuisance.
"Large basements can mean huge numbers of lorry movements, which cause too much disturbance and a risk to other residents."
