The Shard by , also known as the Bridge Tower, is a 72-storey, mixed-use tower located beside London Bridge Station on the south bank of the River Thames. This project was a response to the urban vision of London Mayor Ken Livingstone and to his policy of encouraging high-density development at key transport nodes in London. This sort of sustainable urban extension relies on the proximity of public transportation, discourages car use and helps to reduce traffic congestion in the city.

A mix of uses – residential, offices and retail – creates a that is in use 24 hours a day. The slender and pyramidal form of the tower was determined by its suitability to this mix: large floor plates at the bottom for offices; restaurants, public spaces and a hotel located in the middle; private apartments at the top of the building. The final floors accommodate a public viewing gallery, 240 m above street level. This arrangement of functions also allows the tower to taper off and disappear into the sky – a particularly important detail for Renzo Piano Building Workshop given the building's prominence on the London skyline.

Eight sloping , the “shards” define the shape and visual quality of the tower, fragmenting the scale of the building and reflecting the light in unpredictable ways. Opening vents in the gaps or “fractures” between the shards, provide natural ventilation to winter gardens.

The extra-white used on the Shard gives the tower a lightness and a sensitivity to the changing sky around it, the Shard's colour and mood are constantly changing. It required a particular technical solution to ensure the facade's performance in terms of controlling light and heat. A double-skin, naturally ventilated facade with internal blinds that respond automatically to changes in light levels was developed. The logic is very simple: external blinds are very effective in keeping solar gain out of a building, but unprotected external blinds are not appropriate for a tall building, hence the extra layer of on the outside.

As part of the project, a section of London Bridge Station's concourse was also redeveloped and The Shard by Renzo Piano Building Workshop has been the stimulus for much of the regeneration of the surrounding area, now known as the London Bridge Quarter.


Practice profile:

The Renzo Piano Building Workshop (RPBW) was established in 1981 by Renzo Piano with offices in Genoa, Italy and Paris, France. The practice has since expanded and now also operates from New York. RPBW is led by 9 partners, including founder and Pritzker Prize laureate, architect Renzo Piano.

The practice permanently employs about 130 architects together with a further 30 support staff including 3D visualization artists, model makers, archivers, administrative and secretarial staff. They have a wide experience of working in multi-disciplinary teams on building projects in France, Italy and abroad.

As architects, they are involved in the projects from start to finish. RPBW usually provide full architectural design services and consultancy services during the construction phase. Their design skills extend beyond mere architectural services. Their work also includes interior design services, town planning and urban design services, landscape design services and exhibition design services. RPBW has successfully undertaken and completed over 140 projects around the world.
