TTPP was commissioned by Rail for London (Transport for London) to demolish and re-build the existing station building to include the provision of a new Access for All (AFA) lift and an extended automatic gateline. An additional new lift serves the opposite platform accessed via the overbridge.
The station forms part of the London Overground network.
Hampstead Heath Station is close to the Royal Free Hospital which provided a particular driver for the introduction of lifts to provide step free access to both platforms. Due to the success of the London Overground line that the existing station ticket gateline of two standard gates plus one wide aisled gate (WAG) is not able to cope with passenger flows. Accordingly the brief was also to increase the gateline to five standard gates plus one WAG.
Following Value Management and Value Engineering reviews the selected option was for demolition and rebuilding whilst retaining the platform level sub-structure. This facilitated the Network Rail Approvals Process (Form 001, 002, 003 etc.).
The phasing of the scheme was a particular consideration as it was a requisite that the station remained open throughout the works.
