The new three-storey building - the museum's main entrance, foyer and reception counter, shop, staircase, lift and circulation space - is set in a corner gap of the stadium; exhibition spaces are housed below the terraces.
A free-standing red wall, in the shape of the FM logo (Football Museum), extends beyond the glazed entrance wall and above the roof; it is designed to separate the entrance building from the stadium and to integrate interior spaces. It also acts as a service duct, distributing air-conditioning, water, electrical and waste services.
The wall is a braced SHS steel lattice clad with a rainscreen of red polyester powder coated aluminium panels, waterproofed with a Sarnafil single-ply membrane bonded to 18mm marine ply.
The panels are spaced apart by an aluminium locking strip; some can be removed to give access to service distribution systems. Treated air is distributed through stainless steel input nozzles on the face of the wall and an extract grille on the soffit.
On the west side of the wall, the main roof structure, a series of 203 x 133mm universal beams, is bolted by pinned connectors to a 400 x 100mm PFC set between the aluminium panels. A continuous patent glazed rooflight runs above the beams, fixed to a 300 x 100mm PFC channel. Both channels are fitted with concealed cleats by which they are bolted to the steel lattice.Rooflights have electrically operated vents to give stack ventilation.
The roof structure rests on 254 x 254mm universal columns with 254 x 146mm transoms; they support a frameless glass wall with cast steel boss and cone connectors.
