Swiss Re’s landmark City building at 30 St Mary’s Axe has already attracted a long list of potential bidders who would acquire the building through a joint venture.

Interested parties include ING Real Estate, British Land, Prudential Property Investment Management (PruPIM) and Insight Investments.

The price could reach in excess of £600m meaning the asset is likely to be bought by a syndicate or joint venture. The price is thought to represent a sub 4.5% yield.

Swiss Re has appointed DTZ to market the Gherkin.

The 500,000 sq ft (46,451 sq m) Foster & Partners-designed building is one of the largest assets ever for sale in the UK.

Tenants at the iconic building include Coutts, the private investment bank, law firm Mayer, Brown, Rowe & Maw and law firm Kirkland & Ellis.
