HS2 reveals contemporary design for Kilburn vent shaft

The proposed headhouse features materials chosen to harmonise with the gritty urban setting on a site adjacent to the railway. Mainly comprising a contrasting medley of dark engineering brick and grey softwood timber, the building is articulated by a series of visually distinct orthogonal forms of varying volume which express the functions within. It will be visible from the existing Network Rail lines and local properties.

A mix of different species of tree and shrub will be used all around the structure to create a wildlife habitat, as well as to provide colour and contrast to the varied composition. The building will also have a ‘green’ roof featuring a range of biodiverse planting.

Below the headhouse, a 40m-deep ventilation shaft will extend down to the twin HS2 tunnels, with access provided for emergency services. Tunnel air quality and temperature will be regulated by fans and other equipment which will include smoke extraction for fire scenarios.

A team from HS2’s main works contractor SCS JV (Skanska Costain Strabag) worked with architects from Arup Typsa Strabag to create the design.

James Richardson, Managing Director for SCS JV said:
“As our work ramps up across all of our sites, these exciting designs give a glimpse of how the vital structures will complement the surrounding environment. We are committed to working closely with the local community and look forward to getting their input to help us shape the final designs.”
