The UK’s HS2 has published updated designs for the Canterbury Works vent shaft headhouse and compound, which will provide ventilation to the high-speed rail line for the 4.5-mile-long Euston Tunnel between Euston and Old Oak Common.
The headhouse in South Kilburn, London, will serve as one of four structures that will also be built to provide emergency access to the rail line.
HS2 published the designs as part of an ongoing engagement with the local community.
HS2 design director Kay Hughes said: “The HS2 line through London will be mostly underground in tunnels and this is one of the few visual manifestations of the railway between Euston and West Ruislip.
“Located on a brownfield site, we have been conscious of the proximity of local neighbours and views in developing the design and surrounding landscape.”
Materials for the headhouse structure have been designed to embed the building within the local townscape. Other materials include dark grey engineering brick and grey softwood timber.

It is situated behind Canterbury Road and Canterbury Terrace and will be visible from the existing network rail lines and local properties.
A 40m-deep ventilation shaft below ground level of the building will reach down to the twin tunnels below.
HS2’s main works contractor SCS JV, a team comprising Skanska Costain STRABAG, worked with architects from Arup TYPSA STRABAG for the plans.
Skanska Costain STRABAG joint venture (SCS JV) managing director James Richardson 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.”
