HFD Group has sold 177 Bothwell Street in Glasgow to Spanish investment firm Pontegadea for more than £200m.
The city's largest office building has already been pre-let to tenants such as Virgin Money, BNP Paribas, AECOM, CBRE and Transport Scotland.
Zara owner and Spain's richest man, Amancio Ortega, purchased the building. The billionaire behind the Inditex fashion brand - which also owns Massimo Dutti, Bershka and Pull & Bear - did the deal through his commercial property investment firm.
