The former Bank of Scotland headquarters in St Andrew Square, Edinburgh, is to become an outpost of the luxury Gleneagles golf resort.
Ennismore, which acquired the Ryder Cup venue two years ago for about £150m, is believed to have the bought the city centre listed building from Lloyds Banking Group for conversion to a Gleneagles Club.
The group, which also owns the trendy Hoxton Hotels chain, is likely to convert the premises into a private members club with several bars, lounges, restaurants and event space, as well as a small number of bedrooms.
