Malcolm Turnbull is set to move into an office at Governor Phillip Tower. Illustration: John Shakespeare Credit:

It’s been more than two decades since Malcolm Bligh Turnbull strode into Governor Phillip Tower, rode the elevator to the 48th floor and walked through the smoked glass doors to his desk at Goldman Sachs’ local headquarters.

In a few months the former prime minister will once again have an office in the building.

He's signed on the dotted line to establish his post-political office at the 1 Farrar Place skyscraper.

He’ll be trundling his things — presumably an almost-complete draft of his political memoirs due to be delivered shortly to publisher Sandy Grant — from his temporary digs at 1 Bligh Street.
