Marcus O’Brien

Spear’s Review

Since 2016, Marcus O’Brien has been leading the growth of Beauchamp Estates’ private office team, cutting his teeth under the tutelage of Gary Hersham, a legend within the industry. 

The aim of the private office is to provide a service to high and ultra-high net worth clients, discovering their objectives and keeping a single adviser - often O'Brien himself - as their single point of contact no matter whether they're interested in rural, international or prime central London property, purchase or rental.

In 2020, O’Brien led the sale of Britain’s most expensive house, 2-8a Rutland Gate in Knightsbridge, reportedly sold for £210 million, and has since bought and sold fine country houses including a 200 acre estate in Surrey for £50 million. He reports having achieved ‘one of – if not the – highest-value rental deals in UK history’.
