One Direction heartthrob Harry Styles has reportedly built a bar in the basement of his London home.

The pop star bought the $4.8 million property back in 2012, and he has been busy refurbishing the building, moving the kitchen and creating a social space on the lower level.

A source tells British newspaper the Daily Mirror, "Harry is a really sociable guy, he loves hanging out with friends in cool bars. But wherever he goes, he is subject to a lot of attention.... While all the renovations were going on, he had the idea of creating his own hangout, in the privacy of his own home, where friends could stay until the early hours. It's going to be the ­ultimate boys' den - the design team have taken inspiration from some of the rooms in Harry's favourite bars, like Soho House and Groucho Club... It's due to be finished by the summer."
