LONDON, Oct 21 (Reuters) - Historic London music venue KOKO, where the likes of Madonna, Prince, Amy Winehouse and Coldplay have performed, will re-open next spring following a $100 million revamp. Located in Camden, in northern London, the site, originally a 19th century theatre where Charlie Chaplin once took to the stage before it was turned into a broadcasting centre, has been under construction and restoration for three years. During that time workers have had to overcome a fire and water damage. The refurbished 50,000 square feet (4,645 square metres) venue will offer music artists a 360 degree stage as well as a more intimate setting, and also broadcasting, recording and live streaming facilities. "I"m excited to announce that we will be returning KOKO to the musicians, artists and fans next spring with a beautifully restored theatre and live music offering that will hopefully be a truly unique and unparalleled experience for everyone coming through the doors," CEO and founder Olly Bengough said in a statement on Thursday.

The 70 million pound ($97 million) investment has seen three buildings - the former theatre, an old pub and ex-piano factory - merged, a four-storey extension and the restoration of the theatre"s dome, which was damaged in a January 2020 blaze. Koko, which is being re-launched in partnership with content company Sister, will also feature piano and vinyl rooms, a library, dome cocktail bar, penthouse and a hidden speakeasy. It will also have a radio station and a charitable foundation. ($1 = 0.7241 pounds)
