This development is completed and houses about 110 new build flats.
Most have already moved in (like myself).

An example address is:
Flat ?, Niemann Court
Louis Close
London
N7 0FQ

Addresses can be verified via:

Here (https://github.com/niemann-court/niemann-court.github.io/blob/main/niemann-court-map.jpg, only shows on Google Earth but on Google Maps or its satellite view yet) you can find a map that showcases entrance via Louis Close (road). At the end of Louis Close, you would have to continue on foot through the Niemann Court to the entrance.

I don't know how to create a building outline etc so I'd appreciate if OSM veterans could help complete the picture. Thank you :D
