As in my comment for 18c: If there was ever an area in the UK where large-scale development should take place, it is here. Adjacent to A10, A14, 2 minutes to M11/A428, 15 minutes on bus to city centre, on the guided bus, 50 minutes by train to London, and on the river with excellent cycle tracks. We should build as tall as possible. If someone wants to build a 400m tall building, let them, it will become a feature of Cambridge and show how progressive we are, being far enough out of the centre to have no impact on views there, plus would make the whole of Cambridge North a real destination. I have put in up to 25 storeys on my diagram as I believe this would be extremely viable, although I added one feature building of 6 storeys as I feel this would be the best location for it.
