The planned shift came as co-owner British Land unveiled a new partnership with Singapore Wealth Fund GIC.

The deal follows GIC’s agreement to acquire the 50% interest in Broadgate owned by Blackstone.

The new owners now anticipate a major expansion of the 4 million sq ft City of London site to co-incide with the opening of the adjacent new Crossrail station in 2018.

British Land said: “Looking forward, the joint venture’s strategy will focus on broadening Broadgate’s appeal from a traditional City-focused occupier base to cater for the growing creative district centred around Shoreditch to the East and the emerging tech-focused area around Old Street to the North.

“Plans for the next stage of investment are already underway and include a major refurbishment of 100 Liverpool Street along with a significant expansion of the retail offer around Broadgate South.

“Delivery of this development is expected to coincide with the opening of Crossrail.

Tim Roberts, Head of Offices at British Land, said: “We see a significant opportunity to move Broadgate from a more traditional City-oriented office estate into a vibrant mixed-used campus  serving not just the City but also the emerging districts to the north and east of the City.

“We’ve had an excellent relationship with Blackstone at Broadgate. GIC is a strong new partner with a long history in real estate and we are excited at the prospect of working with the team over the coming years.”

Christopher Morrish, Regional Head, Europe, GIC Real Estate said: “Together we will continue to enhance the value of the asset through active repositioning and redevelopment of the office buildings and by enhancement of the retail and leisure facilities.

“With the improving rail links, this will attract a broad range of occupiers to the estate.”
