The project involves the construction of a new football stadium at White Hart Lane in London – the home ground of Tottenham Hotspur.

The new stadium will provide Tottenham Hotspur with a state-of-the-art sporting and entertainment facility with seating capacity of over 62,000. It will be the first stadium in the UK to feature a retractable dividing pitch - a retractable grass pitch for football and a synthetic surface underneath for National Football League ('NFL') games and other sporting and entertainment events.

Construction of the first phase of the project, comprising the north, east and west stands, took place during the 2016/17 football season whilst the old White Hart Lane stadium was still in operation. Following the last game of the 2016/17 season, the old stadium was demolished and work on the south stand commenced. The main features of this phase are the two architecturally unique steel 'trees' within the south stand, each weighing 275 tonnes. These will support the back of the new 17,500-seater single-tier home stand, which has been designed to generate a 'wall of sound' with the seating bowl arranged to place fans closer to the pitch than in any other stadium in the UK.

This project involved many complex elements from the retractable pitch, where Severfield worked alongside engineering specialist SCX to provide three 3,000-tonne pitch-long steel beds, to the highly-technical roof structure. The new roof is formed from structural tension cables, fixed to a compression ring, which creates the elliptical outside profile of the stadium. The compression ring comprises 54 box girders each measuring around 15 metres long and weighing between 25 to 30 tonnes. The structure was fabricated and trial assembled at our Lostock facility in order to achieve accuracy in length of less than 1 millimetre. On site, the lifting of the 600-tonne roof involved a highly complex sychronised strand jacking operation, involving over 200 strand jacks, making it one of the biggest of these operations ever undertaken in the UK.
