After an absence of six decades, Sir Robert McAlpine has returned to Smithfield Poultry Market, embarking on an ambitious transformation of the site into a key part of the new London Museum. Having originally rebuilt the poultry market between 1961 and 1963 following a devastating fire in 1958, the firm is now tasked with reinventing the market alongside the adjoining 19th-century General Market building. Together, these historic structures will form the new home of the London Museum, scheduled for public opening in 2026.

The Smithfield Market complex, located between Charterhouse Street and West Smithfield in Farringdon, embodies the duality of heritage and modernity. While part of the market continued operating as an active meat and poultry trading site into August 2023, construction began shortly thereafter on the museum conversion. The project is notable for the challenge of working within the footprint of the existing Grade II-listed buildings, requiring intricate logistical coordination to hollow out and refurbish structures without the benefit of external workspace or expansions.

One of the most striking elements of the Poultry Market’s transformation is the insertion of a substantial new steel frame into the original concrete dome structure, fashioned to create additional mezzanine floors and galleries while preserving the building’s historic fabric. This frame threads through the existing architecture, providing space for offices, research laboratories, and public exhibition areas. The museum’s design balances the preservation of original features—including the largest spanning concrete dome in Europe at the time of its construction—with contemporary interventions to enhance visitor experience and functionality.

The construction management contract approach was chosen to mitigate the complex risks inherent in refurbishing such a significant heritage site. The decision reflects an understanding that design-and-build frameworks would have placed unrealistic expectations on contractors facing unknowns related to historic building conditions. Early specialist contracts, including a £12.5 million reroofing package and a £17.5 million demolition and structural works package on the General Market, were integrated into the broader management system once Sir Robert McAlpine was appointed in mid-2023.

Sustainability is a core concern for the project. The use of Cross Laminated Timber (CLT) in the roof conversion stands out as an environmentally conscious choice. CLT is a biogenic material known for carbon storage over its lifecycle, which helps reduce the project’s carbon footprint. Its use also allowed for design flexibility and expedited construction, contributing to the building becoming weather-tight more rapidly compared to traditional materials. This sustainable approach aligns with the broader goal of blending historic preservation with energy-efficient, modern building technologies—such as a district heating system being installed in the basement.

The project is also a symbol of significant change for the site’s wider context. The City of London Corporation decided to close the historic Smithfield meat market after almost a millennium of operation, following the cancellation of a costly relocation plan. While traders will continue at Smithfield and Billingsgate until at least 2028, this decision opens the way for the museum and cultural regeneration of the area—as well as the revitalisation of historic Smithfield shops and bars near the museum site.

Funding for the London Museum reflects its status as one of Europe’s largest cultural projects. A £50 million contribution from the City of London Corporation and Mayor Sadiq Khan has brought the total project investment to £437 million. The museum is expected to attract around two million visitors annually, reflecting its ambition to establish a vibrant, accessible cultural destination. It will also echo London’s unique character as a 24-hour global city, with plans for extended opening hours and broad public engagement opportunities.

As work progresses, the museum complex’s multiple entrances and the newly roofed West Poultry Avenue will offer dynamic access points enhanced with historical artefacts embedded in the concrete floors, further linking the visitor experience to the area’s storied past. Project director Richard Hill acknowledges the mental shift required when refurbishing historic buildings rather than creating new ones, pointing to surprises such as unexpectedly dense reinforcement bars and unrecorded structural details encountered during construction.

The London Museum’s redevelopment of Smithfield Poultry and General Markets exemplifies how architectural heritage can be thoughtfully preserved while accommodating the needs of a modern cultural institution. The site’s transformation will not only conserve a significant chapter of London’s urban history but also breathe new life into a once primarily industrial area, cementing its future as a vibrant cultural and commercial hub.
