Tottenham Hotspur Stadium

The multi-award-winning Tottenham Hotspur Stadium has been the home ground of Tottenham Hotspur football club since its opening in 2019. The stadium was planned by Populous and has a capacity of 62,850 spectators. It has a unique, fully retractable natural grass pitch, making it possible to host NFL games as well. The entire orientation of the stadium is concentrated on the south stand with 17,500 seats, which opens to the outside through a huge glass facade. All stands are inclined 35 degrees to bring fans closer to the pitch for an unforgettable sporting experience. The curved roof merges with the shape of the stadium structure and was realized by BEMO.

The egg-shaped design of Tottenham Hotspur Stadium required a high degree of individualisation of the outer roof ring, the so-called bull nose. BEMO standing seam profiles made of aluminium were used for this purpose, which were manufactured in Germany and crowned in a second step. In an assembly hall in Ireland, the steel frame for the bull nose, including the standing seam sheets, was then prefabricated. These prefabricated elements were then delivered to the construction site and moved into position on the building with a crane.

Due to the segmented design of the elements and the shape of the stadium, geometrical gaps were created between the elements, which had to be closed later.  To do this, the gaps were measured on site and then designed in 3D to provide production data. The shape of the membranes could be summarised in three areas: especially in the area of the facade, free-form in the curve and tapered in the roof area. Custom-made BEMO-MONRO® standing seam membranes were the ideal solution for this.

For the 4,630 m² area of the Bull Nose, a total of 193 prefabricated elements made of 965 standing seam membranes were built, followed by 192 precisely fitting BEMO-MONRO® standing seam profiles.

BEMO plug-in panels were used for the cladding of the roof soffits and in parts of the facade in the interior. The aluminium edge profiles were also manufactured in Germany and then pre-installed in Ireland. The elements were also brought into position on the construction site with a crane and connected to the cable structure.

The total area of the soffits is 21,600m² with 810 individual roof elements, of which each roof element was clad with 22 tapered plug-in panels. Of the total of 17,820 plug-in panels, 7,128 were perforated for reasons of sound absorption. In addition, 2,680 plug-in panels were used in the interior areas of the north and south stands, 1,732 of which were mostly of individual dimensions, which had to be made to fit precisely so that they could absorb the movements from the overall structure and the building expansion joints.
