The Kellogg Tower in Greenford, west London, has been put up for sale after its eponymous occupier launched a 160,000 sq ft requirement for a new home.
US engineering firm Kellogg Brown & Root has appointed JLL to sell the building for £12m as it looks for a new home outside the M25.
The tower is expected to attract interest from developers targeting residential conversions, given its location close to Sudbury Tube station.
KBR bought the building in 2011 for around £10.5m.
It is expected to relocate staff based in the tower to a building closer to its main headquarters at Hill Park Court in Leatherhead, Surrey.
The move is part of a rationalisation of the company’s office estate and comes after unsolicited approaches to buy the tower.
