HS2 have published updates designs for the Canterbury Works vent shaft headhouse and compound, in South Kilburn, London. It will be one of four structures that will be built to provide ventilation and emergency access to the high-speed rail line for the 4.5-mile-long Euston Tunnel between Euston and Old Oak Common.
The designs have been published as part of an ongoing engagement with the local community.
The headhouse features and the materials chosen, are designed to embed the building within the local townscape. A variety of materials used in the design, with dark grey engineering brick, and grey softwood timber making up much of the structure.
Situated behind Canterbury Road and Canterbury Terrace, the structure will be visible from the existing network rail lines and local buildings.
The structure will be surrounded by planting, with a mixture of tree and shrub species creating an enhanced bio-diverse habitat for wildlife. The building roof will be covered with a green-roof containing a range of biodiverse planting to improve sustainability.
A below ground level 40-meter-deep ventilation shaft will reach down to the twin tunnels below, with fans and other equipment above ground designed to regulate air quality and temperature, remove smoke in the event of a fire and provide access for the emergency services.
Kay Hughes, HS2 Ltd’s Design Director 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. I hope that the design will be welcomed by the local community.”
James Richardson, Managing Director for Skanska Costain STRABAG joint venture (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.”
