Strategic Real Estate Investors, the global property fund and asset manager, is poised to sell its last UK property.

The company, which specialises in property investment and management for wealthy investors and families, is to sell the Turner building on Bath Road in Slough to a private investor for more than £45m. The sale will complete before Christmas.

The price is slightly higher than the asking price and reflects a yield of around 5.5%.

The property was previously under offer to a UK institution but the transaction collapsed.

The 86,780 sq ft (8,062 sq m), four-storey office is let to household cleaning products manufacturer Reckitt Benckiser until 2020 at around £30/sq ft (£322.92/sq m).

StratReal was unavailable to comment on the sale but it is thought that the company, headed by chairman and chief executive Pierre Rolin, has called time on the UK investment market and will look to commit its funds elsewhere.

The company has had £3.8bn of real estate assets in 25 countries under management since its inception in 1998.

Last month it sold the former 200,000 sq ft (18,580 sq m) Sir Edwin Luytens-designed bp headquarters, Britannic House at 1-6 Finsbury Square in the City of London, to Hermes for £165.25m.

Knight Frank is advising StratReal but also declined to comment on the sale.
