Thank you for your request of 25th April 2021 asking for information about the Northern Line Extension.
Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.
Specifically you asked:

Please see the following link to the ‘deposited plans’ which contains most of the material requested:
The entire NLE is captured in the deposited plans, but a further map of the full line (albeit less detailed) is also attached separately. The “NLE - Kennington Loop” attachment may also be of interest. I understand that you have also recently received a copy of a Noise Investigation report (dated 4 May 2021) which contains a map of the area directly around your property. Note that: - Step Plate junctions are shown in the deposited plans and are the points where the blue line meets the black lines of Kennington Loop in the attached NLE map. - the platforms at Kennington are shown on Sheet No.7 of the deposited plans (shaded in green); - while gallery tunnels were in the concept design for the control of ground movement, in the detailed design we eliminated the galleries and associated pressure grouting and reduced the number of headwalls from 5 to 3 at both junctions and in doing so reduced the length of the junctions and thus the overall impact from ground movement. The exisitng Northern Line can be found here (you can use the +/- to zoom in and out): https://arcg.is/19Wfvj
