Project Overview
ExCeL London’s Phase 3 expansion added 25,000 sq m of new event space to the east of the existing venue, supporting its position as one of Europe’s leading fully integrated conference and exhibition centres.The multi-million-pound development introduced a range of flexible, modern spaces, including new plenary rooms, adaptable meeting halls and purpose-built convention facilities designed to host large-scale global events.The expansion also includes a unique Formula E racetrack integration, with an indoor-to-outdoor track connection and an 18-metre-wide sliding glass façade allowing racing cars to enter the venue directly.
The Challenge
The Phase 3 expansion was a technically demanding project, combining large-scale venue construction with highly flexible event spaces and specialist operational requirements.The project included moveable wall systems, modular meeting spaces, elevated construction areas and infrastructure to support major conferences, exhibitions and live event use.As a high-profile public venue, the project required careful commissioning management, structured QAQC control and close coordination to ensure that building services were delivered, tested and completed in line with the venue’s operational demands.
Our Approach

These spaces can be configured for a wide range of uses, from smaller boardroom-style meetings to large-scale events with thousands of attendees.The expansion also added major structural scale to the venue, extending the facility to approximately 820 metres in length and incorporating 4,500 tonnes of steelwork at the eastern end of the campus.
