Tishman Speyer has completed the first phase of renovation at 23-27 St James’s Street, Alison and Peter Smithson’s last remaining building in London.
The Grade II*-listed complex, previously known as ‘The Economist Plaza’ was originally home to The Economist Magazine which commissioned and occupied it for more than half a century. Under Tishman Speyer’s stewardship, the estate is undergoing a substantial refurbishment and is being renamed ‘Smithson Plaza’ to celebrate the acclaimed architectural duo. The first phase renovation works consists of upgrading the buildings and the plaza to deliver a renewed destination and prime office space for St James’s while reconnecting with the Smithsons’ original design.
Smithson Plaza was designed and built between 1960 and 1964 and is widely recognised as a triumph of post-war Brutalist architecture. The scheme’s significance is founded on its urban contribution, as much as that of the individual buildings. The three buildings arranged around a raised plaza comprise the 15-storey Smithson Tower (formerly known as The Economist Tower), the five storey Bank Building and eight storey Residential Building.
Following the acquisition of the estate in 2016, Tishman Speyer appointed London-based architects DSDHA with the strategic brief to safeguard the future of the estate through considered investment in the buildings and their public realm, enhancing their historic significance and longevity, while delivering best-in-class and environmentally sustainable accommodation. The proposal received support from 20th Century Society and Historic England.
Dan Nicholson, Managing Director of Tishman Speyer UK, said: “Our strategy was to reposition the Smithson Plaza as a best-in-class West End office destination while safeguarding its historical significance for future generations. With the completion of the works in the coming weeks, we are now very close to achieving these goals and we look forward to unveiling this architectural icon to the public in the near future.”
Deborah Saunt, Founding Director of DSDHA, said: “DSDHA is proud to be working on the restoration of the former, Grade II* listed Economist Plaza. Having considered the impact of incremental changes since 1964, we have assessed what might be preserved and what can be changed. We have developed a phased restoration framework to create sustainable, flexible and contemporary workspaces whilst preserving public amenity.”
This first phase marks a new chapter for Smithson Plaza and DSDHA’s masterplan framework is being implemented with the need to accommodate existing occupiers. The trio of buildings and the plaza are being fully renovated through a phased approach, bringing the buildings to a 21st-century performance level while restoring their aesthetic, true to the Smithsons’ original design.
