Evans Randall is looking for a 33% mark-up on its only West End asset, which it bought last year.
The investment bank has decided to sell 15 Sackville Street, W1, after making it a highly sought-after Mayfair office destination.
It is readying a sale of the 34,000 sq ft building and will seek offers in excess of £80m.
Evans Randall bought the property off-market in February 2013 for around £60m from Mitsui Fudosan with senior debt provided by Aareal Bank.
Since the purchase it has signed up a number of luxury services tenants, including Four Seasons Hotel Group and yacht broker Camper & Nicholsons.
Rents have reached £107 per sq ft.
When the property became fully-let last month, Evans Randall chief executive Kent Gardner said: “Our ability to attract such high-calibre occupiers has increased the investment appeal of the asset, which sits at the heart of one of London’s premium business locations.”
The Mayfair property could hit the market as early as July, according to London sources.
Evans Randall has recently been pursuing new opportunities across a variety of regions and asset types.
Last month, it agreed to forward fund the initial phase of Interserve’s and Tiger Development’s mixed-use plans for Haymarket in Edinburgh for £100m, and it is currently in talks to buy the Cameron Toll shopping centre in Edinburgh for £45m.
