The Shard was one of the most ambitious projects of the London South Bank regeneration and since its inauguration in July 2012 it has become one of the most recognizable and iconic buildings of the London skyline.
The initial vision on the part of Irvine Sellar, the developer and joint owner, was to create a ‘vertical city’ that would be capable of incorporating retail, offices, hotel accommodation, apartments, restaurants and a public viewing gallery. The site is in the busy transport hub of London Bridge, where Sellar acquired Southwark Towers in 1998. After meeting in 2000, the architect Renzo Piano began work on designing a church spire-like structure that would appear to emerge ‘like a shard of glass’ from the River Thames.
A planning inquiry was launched in 2002 following opposition from the Commission for Architecture and the Built Environment (CABE) and heritage bodies such as English Heritage (now Historic England). In 2003, Deputy Prime Minister John Prescott announced that planning consent had been approved.
In 2007, building contractor Mace were awarded the contract for a fixed price of £350 million, a figure that would increase to almost £435 million in 2008. The global economic recession threatened the viability of the project, until the State of Qatar agreed to buy out the original stakeholders, in the process consolidating their ownership of the London Bridge Quarter developments.
Renzo Piano’s tapered design was inspired by the geometry of the railway lines running past the site, London’s church spires and the masts of sailing ships. A sophisticated form of glazing was proposed which would feature facades of angled glass panes to reflect sunlight and the sky above, so the building would appear to blend into the sky and change with the seasons and weather.
In a pioneering step, the foundations were excavated according to a top-down method that allowed for the core of the first 23 storeys to be built upward simultaneously. This was necessary due to the challenge faced of constructing a skyscraper in a built-up area adjacent to a major transport hub and was instrumental in the developer completing the project so quickly. In addition to the top-down method, structural engineers and contractors secured several notable achievements for UK construction:
- The UK’s largest concrete pour.
- The first use of jump-lift construction.
- The first inclined hoist in the world.
- The first crane to be supported on a slipform.
The distinctive tapered form consists of the following structues:
- First 40 floors: Composite steel frame.
- Up to 60th floor: Post-tension concrete frame.
- Up to 72nd floor: Traditional reinforced concrete frame.
- Spire to 87th floor: Pre-fabricated steel.
The building features 11,000 panes of glass, with a total surface area of 56,000 sq. m (600,000 sq. ft).
The Shard was inaugurated on 5 July 2012 by the Prime Minister of Qatar in a ceremony attended by Prince Andrew, Duke of York and featuring a spectacular laser light show.
In accordance with the original idea of a mixed-use ‘vertical city’, the building includes the following accommodation:
- More than 55,000 sq. m of office space over 25 floors.
- Three floors of restaurants.
- A 17-storey hotel.
- 13 floors of apartments.
- ‘The Sky Boutique’ on the 68th floor, the highest shop in London.
- The View from the Shard: a tourist attraction incorporating a triple-level indoor gallery on the 69th floor as well as an open-air observation deck on the 72nd floor.
