The Leadenhall Building receives best commercial building at the NLA Awards

RSHP’s Senior Partner, Graham Stirk, received the prize for best commercial building at New London Architecture awards ceremony today at The Guildhall in the City of London.

The Leadenhall Building is a 50-storey tower opposite Lloyd’s of London and rises to a height of 224.5 metres (802 feet). Its slender form creates its own distinctive profile within an emerging cluster of tall buildings in this part of the City of London. The building’s tapering profile is prompted by a requirement to respect views of St Paul’s Cathedral, in particular from Fleet Street. The tower’s design ensures that from this key vantage point the cathedral’s dome is still framed by a clear expanse of sky.

The office floors are designed to meet the highest quality office space standards taking the form of rectangular floor plates which progressively diminish in depth towards the apex. Instead of a traditional central core providing structural stability, the building employs a full perimeter braced tube which defines the edge of the office floor plates and creates stability under wind loads. The circulation and servicing core is located in a detached north-facing tower, containing colour-coded passenger and goods lifts, service risers and on-floor plant and WCs.

The building’s envelope expresses the diversity of what it encloses, reinforcing the composition and providing legibility to the primary elements. Although the tower occupies the entire site, the scheme delivers an unprecedented allocation of public space – the lower levels are recessed on a raking diagonal to create a spectacular, sun-lit seven-storey high space complete with shops, and soft landscaped public space.

This public space offers a half-acre extension to the adjacent piazza of St Helen’s Square and provides a rare breathing space within the dense urban character of the City of London.
