Kidbrooke

We will be building a permanent shaft and headhouse at our site at Kidbrooke. The shaft and headhouse will be used for ventilation and as a permanent access route for the tunnel once it is built.

Our site at Kidbrooke is located on land next to the National Maritime Museum Collections Centre building. We have agreed the rights to this land.

The tunnels and shafts will be build under our permitted development rights.

There are points along the tunnel route where we will be building headhouses to cover the shafts. Headhouses are required for ventilation and as a permanent point of access for the tunnel once it is built. In February 2019 the Royal Borough of Greenwich granted National Grid planning permission for the construction of a headhouse at our site at Kidbrooke

The granting of our planning application follows a series of public information events we held at various locations across our route during 2018, where members of the public found out more about our works and the wider project and gave us some helpful feedback.

Key facts:

  • Dimensions: The shaft will be approximately 10.5m in diameter and up to 35m in depth. The headhouse will have a maximum footprint of 15m by 15m and will reach a maximum height of 10m.
  • Working hours:Our working hours will be from 7am to 5pm Monday to Friday, and 8am to 1pm on Saturdays. There will be no work on Sundays or Bank Holidays. Occasional out of hours work may be necessary and we will keep you informed about this.
  • Traffic movements:We anticipate there will be approximately 8 HGV movements per day during shaft construction, and 4 per week during headhouse construction.
  • Access:Our construction vehicles will use Nelson Mandela Road to enter and leave the site.

Timeline:

  • We plan to start works in October 2021 until August 2027.
  • Shaft construction works are anticipated to take place between October 2021 and March 2022.
  • If our application for the headhouse is approved, this will be built between February 2023 and November 2023.
