Described as being "like the private residence of the Zetter's eccentric great aunt, full of art collected from her travels abroad", the new property will have 11 bedrooms, two suites, a lounge and a cocktail bar.
"It will be contemporary and slightly dotty, eccentric and even wacky, but chic, cool and quintessentially English," a spokesman said. The design will be by Russell Sage.

It has recently received renewed interest with the arrival of chef Bruno Loubet at its restaurant
