The Leadenhall Building at 122 Leadenhall Street, is popularly known as ‘The Cheesegrater’ because of its distinctive slanting profile, created to respect a protected view of St Paul’s Cathedral from Fleet Street. It was designed by architects Rogers Stirk Harbour + Partners (RSHP) for The British Land Company plc and Oxford Properties.

The building comprises a number of architectural elements that provide clarity to the composition both as a whole and as a legible expression of its constituent parts:

* The primary stability structure.
* The ladder frame.
* The office floor plates.
* The northern support core.
* The external envelope.
* The public realm.

The structure aims to reinforce the geometry defined by the development envelope, which in turn creates the distinctive tapering form, and takes the form of a perimeter braced ‘tube’ that defines the extent of the floor plates. The ladder frame contributes to the vertical emphasis of the building, and encloses the fire-fighting cores. The frame also visually anchors the building to the ground.

The office floors take the form of simple rectangular plates which progressively diminish in depth by 750 millimetres towards the apex. They are connected to the structural ‘tube’ at every level without the need for secondary vertical columns at the perimeter.

The northern support core is conceived as a detached tower containing the passenger and goods lifts, service risers, on-floor plant and WCs. Three groups of passenger lifts serve the low, mid and high rise sections of the building, and are connected by two transfer lobbies at levels 10 and 24.

The position of the northern support core relative to the offices means the structure is not required to be over-clad with fire protection, allowing it to be designed and expressed as visible steelwork. This articulated steel frame provides clarity to the whole assemblage.

The building is designed to express all the constituent elements behind a single glazed envelope. Facades to the office areas require the highest comfort criteria in relation to heat loss, daylight, glare control and solar gain. Here, the facade is supplemented with an internal layer of double-glazing, forming a cavity which incorporates the structural frame.

The external glazing incorporates vents at node levels to allow outside air to enter and discharge from the cavity. Blinds in the cavity automatically adjust to limit unwanted solar gain and glare.

The lower levels of the building are recessed on a raking diagonal to create a large public space that opens up to the south. The spectacular scale of the semi-enclosed, cathedral-like space is without precedent in London and creates a major new meeting place and a unique destination.

Overlooking the space are generous terrace areas within a bar and restaurant that provide animation and views into the public space and beyond. This enclosure is open at ground level to give access from all directions.

In January 2015, RSHP announced they had taken a 15-year lease on level 14. They moved in on 14 December 2015, leaving their long-term home by the river in Hammersmith.

The Leadenhall Building was officially opened by the Duke of Cambridge and Prince Harry on 19 October 2015. See Leadenhall building opening ceremony for more information.

On 1 March 2017, it was announced that the building had been sold by British Land to CC Land, a Hong Kong-listed company controlled by Cheung Chung-kiu. At £1.15 billion, it is the second-biggest ever sale of a UK building.

RSHP:

Rogers Stirk Harbour + Partners (RSHP) is an award-winning, international architectural practice based in London. Over three decades, RSHP has attracted critical acclaim with innovative projects across Europe, North America and Asia. The practice is experienced in designing a wide range of building types including: office, residential, transport, education, culture, leisure, retail, civic and healthcare. The quality of its designs has been recognised with some of architecture’s highest awards, including two RIBAStirling Prizes, one in 2006 for Terminal 4, Madrid Barajas Airport and the other in 2009 for Maggie’s Cancer Care Centre, London.

Set up as The Richard Rogers Partnership in 1977, the practice became Rogers Stirk Harbour + Partners in 2007 to reflect the growing importance of two of the younger Partners, Graham Stirk and Ivan Harbour, and their role alongside Richard Rogers in the practice’s future. RSHP now employs over 200 people, including 9 Partners, 10 Associate Partners and 57 Associates, in offices in London, Sydney and Shanghai.

A democratic philosophy is employed at every level, to enable all staff to collaborate and contribute their individual expertise. Weekly meetings – open to all employees – provide a vital forum for discussion of current competitions and on-going projects, as well as a platform for creativity and new solutions appropriate to each design. This collegiate approach to the work of the practice is embodied in a constitution that consciously brings a social dimension to our work and takes the form of, among other initiatives, a staff profit-sharing scheme and significant contributions to charity.

"Architecture is a team-working process and rarely a lone activity. There is always a client and there is always an interpreter of that client’s needs. The relationship between client and architect is fundamental, and the establishment of a professional and trusting relationship between the two is the bedrock of every successful project...."
