The points thrown up included rebuilding a mini conservatory/lean to a bit of repointing to chimneys etc, lowering ground levels around the property and some testing of drains etc...
Lean-to: House was valued to sell with it being in that condition - if it had already been rebuilt the asking price probably would have been higher.
Pointing: wear and tear (surveyor justifying his fee)
Drains: As above and there may be nothing wrong at all.
In your favour is the fact that you're not involved in a chain.
In the vendors favour is the fact that there's loads of buyers out there - if I were them I'd suggest you stick your reduced offer and move on to the next buyer
Edit: Ground levels - if they're above the DPC it's not a good thing and should be lowered. Not something you can negotiate on though really unless surveyor has found damp - even then it's up to you.
I realise you want to save money, but you need to remember that houses do wear and stuff needs fixing - the chances of moving into a house and it being 100% are fairly slim.... and that includes new houses!
You're at the start of your property 'journey', if you like the house just get on with it.
