Kennedy Wilson has paid £41.3m (€46.6m) for a 200-acre office campus in South East England.
The global real estate firm, together with its equity partners, have bought Ditton Park.
The asset was previously owned and occupied by Computer Associates, as its UK headquarters, prior to its sale to global technology supplier Broadcom.
Ditton Park provides 195,000sqft of offices and a 44,000sqft manor house. The campus is located close to the M25 and Heathrow Airport, between Slough and Windsor.
Mike Pegler, head of UK of Kennedy Wilson, said: “We see a very attractive opportunity to grow net operating income through refurbishment and lease-up by presenting the offices in their entirety to the leasing market for the first time.
“Alongside these plans, there are multiple angles for asset management upside, which will see Ditton Park transformed into a vibrant mixed-use campus.”
