Residents living in a posh 'Millionaire's Row' suburb have reacted with anger after it emerged their local tea room may be operating as a brothel. 

Neighbours have complained about pool parties and anti-social behaviour at the detached house in the exclusive Four Oaks area of Sutton Coldfield, West Mids. 

Plans to turn the property into a "by appointment only" tearoom were rejected after locals raised concerns no other cafes operated under "such strange conditions". 

The "Ye Olde Tea House" wants to open seven-days-a-week from 9am until midnight - with three themed rooms being booked out for two-and-a-half hour appointments. 

The curious application even suggested customers could book an Alice in Wonderland themed afternoon and use a converted rear living room as a function room. 

Local politicians have also expressed their dismay at the proposals in the affluent suburb by saying: "That doesn't sound like Starbucks to me." 

One resident living nearby, who did not want to be named, added: "I was ignorant for a long time. 

"I thought we had a nice quintessential English tea room as you'd expect around this area. 

"But it turns out its some sort of seedy sex den. I was utterly mortified." 

Owner Aaron Smithson, from Edgbaston, Birmingham, also asked for permission for a decorative windmill to be added to the property,. 

He sought additional permission for an external staircase to provide access to a bedroom and permission for 14 car parking spaces and signs. 

The application's supporting statement added: "Number of visitors will are hard to speculate as this is a new somewhat unique business. 

"Appointments will last approximately 2-4 Hours." 

Birmingham City Council rejected the application for tearoom signs at the property, as well as a bid for a themed by-appointment-only tearoom in May this year. 

But signs reading "Tea House" have been put up on railings at the property in the leafy suburb, with parking bays painted on the drive. 

The exclusive Four Oaks estate is one of the most upmarket areas of the West Midlands where houses average over half a million pounds. 

It is described as the 'Millionaires Row' of the region and is home to Premier League footballers as well as wealthy entrepreneurs and celebrities. 

A council enforcement team is now investigating if the detached house has become a legitimate business after neighbours claimed it was being used as a sex den. 

The owner of the property also failed to take down contested Tea House signs before an inspection on August 22 and could now face prosecution. 

Tory councillor Meirion Jenkins, who represents the Sutton Four Oaks ward on Birmingham City Council, described the application as "extremely troubling". 

He said: "It's a very bad situation. The neighbours are really distressed. It's very, very unfortunate the whole thing. 

"I am being told by residents that the property may be being used as a brothel. 

"They are extremely upset. They are highly sceptical about what the purposes of this building is. 

"The council have tried to arrange a meeting with the owner to allay the residents' concerns. 

"There were numerous objections to the application including from councillors. 

"The senior enforcement officer at Birmingham City Council dismisses the claim the property has been known as The Tea House and even if it was that still doesn't give you the right to put big signs up." 

Cllr Jenkins also questioned the need to take bookings until midnight and said there were rumours of ticketed late-night pool parties. 

He added: "That doesn't sound like Starbucks to me. 

"It's entirely and quite obvious that a tearoom by appointment is not a genuine tearoom. 

"It's really upsetting the neighbours. It's easy for me to talk about it, but they are living in it every day." 

Council chiefs received 26 letters of objection from nearby residents including a letter from Irwin Mitchell solicitors on behalf of one of them. 

A spokeswoman on behalf of the owner or occupier of the Streetly Lane property said the house had been known as the Tea House for more than 100 years. 

They also claimed the occupant "knew nothing of the planning application, was unhappy with its content and the house was never intended to be a business". 

A spokesperson for West Midlands Police said: "Police are investigating after receiving complaints of anti-social behaviour in Streetly Lane, Four Oaks. 

"Officers are working with partner agencies to help resolve the concerns of local residents. 

"To report anti-social behaviour please call us on 101 or 999 in an emergency." 

Birmingham City Council's head of planning management, Richard Goulborn, added: "We have had a number of complaints about The Tea House and can confirm that we are investigating."
