Conservationists have labelled plans by Soho House's US billionaire owner to build a six-bedroom Cotswolds mansion as 'out of proportion'.

Locals in Little Tew have been battling against Ron Burkle's bid to build a lavish six-bedroom country pile on farmland in the quaint Cotswolds idyll, and have now been joined in their objections by the conservation group.

Mr Burkle, who owns celebrity hotspot Soho House and Michael Jackson's former Neverland ranch, has rubbed shoulders with Elton John and the Duchess of York, Sarah Ferguson.

He hopes to construct a six-bedroom house which would have a gun room, lift, entertainment room and wine store, several reception rooms, a butler's pantry and a domed entrance hall said to be inspired by the Pantheon in Rome.

The sprawling manor house would also feature a natural swimming pool, bather's pavilion in the 'pleasure ground' area, stable block and estate manager's cottage plus a circular lawn that may be a helipad.
