HS2 shows off revised plans for Camden ventilation shaft

Revised plans for HS2’s headhouse building in Camden have been published ahead of a series of public consultations on the design.
The headhouse is the proverbial iceberg, being the top of a large subterranean structure that will provide ventilation and access to the HS2 tunnels running to Euston station. It is one of five structures that will be built along the 4.5miles of tunnels between Euston and Old Oak Common.
The Adelaide Road headhouse is located between Chalk Farm Road and Primrose
