The Leadenhall Building tops out

A ceremony to mark the topping-out of The Leadenhall Building was attended by Boris Johnson, Mayor of London, on Tuesday 18 June. Owned by the 50:50 joint venture between British Land Company PLC ("British Land") and Oxford Properties ("Oxford"), the building, opposite Lloyd's of London in the heart of the City of London, has been under construction since early 2011. It is due to complete in summer 2014 and will comprise 610,000 sq ft of office space over 47 floors.

The striking architectural design of The Leadenhall Building incorporates 18,000 tonnes of steel and 70,000 sq metres of cladding. In one of the most advanced forms of construction by main contractor, Laing O’Rourke, 85% by value of the construction has been pre-fabricated off-site ensuring the highest quality of specification. Steel components have been manufactured and assembled as far as afield as Northern Ireland, transported to the site and lifted into place.

As well as being the newest addition to London’s skyline, The Leadenhall Building will be part of the City's fabric at ground level, creating a half acre, seven storey galleria which will include formal lawns, seating, mature trees, retail units and an actively managed events space, creating a vibrant and welcoming environment open to the public.

The Leadenhall Building was designed by Graham Stirk, partner at world-renowned architecture practice Rogers Stirk Harbour + Partners. The building's distinctive tapered profile has been designed to protect the sight line of St Paul's Cathedral. Unusually for a tall building, The Leadenhall building has no central core, with an external mega frame providing the lateral stability and the 26 passenger lifts housed in the building's Northern Core, painted bright yellow, at the rear of the building.

Graham Stirk, Rogers Stirk Harbour + Partners said “We’re very proud of this moment in the project’s history and contributing to what is the product of all the hard work from thousands of people. This effort is reflected in the very fabric of the building. All aspects of the construction are beautifully celebrated in the design to form a dramatic architectural expression which will become even more evident on completion in a year’s time.”
