Funny you should mention the fence, I actually added this to the comment to the hospital. When it's all done the fence needs to be at least 6 foot BOTH sides and if it's effectively shorter their side at the moment is there earth piled against your fence that could be damaging it? Did you not know about the hospital when you bought your house. You say you moved in in November. Your solicitor was seriously lapse if it wasn't mentioned. When it's done, the landscaping should screen you. Have you seen the landscaping plans? They are available from Planning at City Council, drop a note to
zoe.raygen@lincoln.gov.uk and she can point you where you can see them if you like. The 'path' if not on the plans may just be what the builders are using at the moment and not a long term thing. Again Zoe can point you to the most up to date plans to check on this.
