Is Sheffield’s latest urban attraction facing a concrete catastrophe?
In the heart of Sheffield, a city renowned for its resilience and industrial heritage, plans for a vibrant new shipping container complex have hit an unexpected snag. The much-anticipated STACK Sheffield, envisioned as a bustling hub of food, music, and culture, has been delayed due to an unforeseen structural hiccup: the discovery of ‘crumbly concrete’ in the roof of the adjacent O2 Academy. This revelation has not only postponed the project’s progress but also raised questions about the integrity of some of the city’s beloved structures.
The Rise of STACK Sheffield
Sheffielders were abuzz with excitement when plans for STACK Sheffield were unveiled in October 2023. The proposed development on Arundel Gate, nestled between the O2 Academy and the Odeon Cinema, promised to inject new life into the city centre. The design featured an array of shipping containers artfully arranged over two floors above the existing Arundel Gate car park, all centred around a spacious covered plaza. With live music, diverse street food vendors, lively bars, and a giant screen for communal viewing, it was poised to become a cultural cornerstone.
STACK, the brainchild behind similar successful ventures in Seaburn, Lincoln, Newcastle, and Middlesbrough, had ambitious plans for Sheffield. The developers projected that the attraction would draw in a whopping one million visitors annually, with an anticipated opening in spring 2025. However, as the months rolled by, the site remained conspicuously untouched, leaving many to wonder about the cause of the delay.
The ‘Crumbly Concrete’ Dilemma
The root of the postponement lies in the unexpected discovery of reinforced autoclaved aerated concrete (RAAC) in the roof of the O2 Academy. Often dubbed ‘crumbly concrete’ due to its less durable nature, RAAC has been identified in various structures across the UK, leading to safety concerns. The O2 Academy, a cherished music venue in Sheffield, has been shuttered since September 2023 following the identification of RAAC in its roofing.
The plot designated for STACK Sheffield shares ownership with the O2 Academy building. Consequently, the structural issues plaguing the academy have directly impacted the progression of the STACK project. To address these concerns, a new planning application has been submitted, seeking permission to replace the compromised roof of the O2 Academy. This move is essential not only for the reopening of the music venue but also to pave the way for the commencement of construction on STACK Sheffield.
A Broader Perspective on RAAC
The discovery of RAAC in the O2 Academy is not an isolated incident. Across the UK, numerous buildings constructed between the 1950s and 1980s have been found to contain this material. Initially favoured for its lightweight and cost-effective properties, RAAC has since revealed vulnerabilities, particularly as it ages. Structures incorporating RAAC have reported issues like reduced load-bearing capacity and increased susceptibility to moisture ingress, leading to potential safety hazards.
In recent years, heightened awareness of RAAC’s shortcomings has prompted widespread inspections and, in some cases, the temporary closure of affected buildings. The situation in Sheffield underscores the importance of proactive structural assessments, especially in ageing urban infrastructures.
The Path Forward
While the delay is undoubtedly a setback, both the developers of STACK Sheffield and the operators of the O2 Academy are committed to resolving the issue promptly. Replacing the RAAC-laden roof is a priority, ensuring the safety of patrons and the longevity of the structures. Once the roof replacement is completed and necessary safety clearances are obtained, construction of the STACK complex can proceed.
The enthusiasm surrounding STACK Sheffield remains palpable. The project promises to be a significant boon for the city’s economy, offering a dynamic space for residents and visitors alike to enjoy diverse culinary offerings, live entertainment, and cultural events. The temporary delay, while unfortunate, is a prudent measure to ensure the safety and success of the venture in the long run.

To appreciate the potential impact of STACK Sheffield, one need only look to its northern cousin, STACK Newcastle. Launched in 2018, STACK Newcastle transformed a vacant city centre lot into a vibrant social hub using repurposed shipping containers. The venue quickly became a favourite among locals and tourists, offering an eclectic mix of street food, retail outlets, and live entertainment.
Despite initial scepticism about the concept, STACK Newcastle exceeded expectations, attracting over two million visitors in its first year. The success was attributed to its unique blend of offerings, community-centric events, and a flexible space that could adapt to various functions—from yoga classes in the morning to live music gigs in the evening.
The positive economic impact was also noteworthy. The venue provided a platform for local entrepreneurs to launch and grow their businesses, creating jobs and stimulating the local economy. Moreover, it revitalised a previously underutilised area, enhancing the city’s cultural landscape.
The experience of STACK Newcastle serves as a compelling example of how innovative urban projects can rejuvenate city spaces, foster community engagement, and drive economic growth. It bodes well for the future of STACK Sheffield, suggesting that once the current hurdles are overcome, the city can look forward to a similarly transformative addition to its urban fabric.
