Mapletrtee Investments is in discussions to buy Green Park from Oxford Properties for £500m.
Oxford will continue to asset manage the 3m sq ft park until the end of 2016 to ensure a smooth transition of the management and operations with occupiers having been informed of the change in ownership.
The 195-acre Green Park is one of the largest business parks in Europe. Its occupiers include Chinese technology company Huawai, defence firm Thales and drinks giant PepsiCo.
Oxford, the real estate arm of the Canadian pension fund OMERS, acquired the park in 2011 for £400m from M&G Real Estate.
Last year, Oxford appointed Eastdil Secured to seek a £300m refinancing for the park but that process has now been superseded.
The deal is the second in quick succession where Oxford has worked with a property company backed by the Singaporean government. In October last year Oxford entered a joint venture with Temasek to buy the Blue Fin Building, SE1 for £415m.
