The Chilterns AONB HS2 Detailed Design Principles

Detailed Design Principles (DDP)

The draft Detailed Design Principles (DDP) document has been produced in response to an Assurance provided by HS2 during the passage of the High Speed Rail (London - West Midlands) Act 2017 through Parliament: namely, that this guidance would be used by HS2 and their contractors to inform their design through the Chiltern’s Area of Outstanding Natural Beauty (AONB).

The document has been written by landscape architects LUC, on behalf of the AONB Review Group in collaboration with the following organisations: Chilterns Conservation Board, Buckinghamshire Council, Buckinghamshire Council, Natural England and HS2 Ltd.

This document, a technical advice note, is intended to advise and inform the designers appointed by HS2 about the special landscape qualities of the AONB and to afford the said principles due weight and consideration in their design of the railway.
