Saltire Court, one of Edinburgh’s most prestigious office blocks, has been put up for sale by Abu Dhabi Investment Authority (ADIA) for about £69 million, according to a report in Estates Gazette.

ADIA bought the building from Scottish Metropolitan in 1993 for £53 million.

The block on Castle Terrace is the Edinburgh base of blue chip tenants including Deloitte, KPMG and fund managers Martin Currie.

The sovereign wealth fund’s asset manager, Aberdeen Asset Management, has appointed Cushman & Wakefield to market the 180,000 sq ft office building, the report said.

Saltire Court is thought to be the largest real estate investment opportunity currently available in Scotland.

Steven Newlands, partner, capital markets, at Cushman & Wakefield, said: “We are really excited to be involved in such a landmark sale. It has got international appeal for a variety of different reasons.”
