To build so many houses NE of Baldock up to Bygrave seems a little excessive, to say the least!
The need to provide more housing for the UK is understandable but let's be proportional about this. Thirty odd years ago a Baldock northern bypass was thrown out because of unsuitable sub soils in the area yet now you're proposing to build houses on the same land - not a good idea I would like to state. Further, planned infrastructure is far from suitable for so many more residents for the area.
I suggest you give these plan some very careful consideration.
