News on HS2 in Bucks & Oxfordshire

We have launched the design for the Amersham Ventilation Shaft headhouse, one of five structures that will be built to provide ventilation and emergency access to the high-speed rail line’s 16 kilometre-long Chiltern tunnel. Set in the middle of a road junction just outside the town, the circular single-storey building will be surrounded by a spiral shaped weathered steel wall designed to echo the shape of the site and the natural tones of the surrounding landscape.

The Amersham Ventilation Shaft is a Key Design Element, which means it is a significant structure. We want it to respect its surroundings and the local area as much as possible and we would like your views on the design of the ventilation shaft including:

Due to COVID-19 we are not able to hold face-to-face public events, but we will be holding a series of online information events in September to share information about the design and construction of the ventilation shaft. These online 'webinars' will give residents the opportunity to hear and ask questions about the Amersham Ventilation Shaft. C lick here to register for one of our webinars .

Please view our Amersham Ventilation Shaft information boards before completing our online survey . The survey will be available to complete until midnight on Sunday 27 September .
