"Banks/EBS etc. will not finance without some kind of planning agreed - so what are my options?"
They won't give a homeloan mortgage, but €180k for 14 acres is les than €13k\acre - not all that much above straight agricultural price in many parts of the country, and indeed below it in some.
Banks lend for land purchases all the time. It should be possible for you to get money if you have adequate income and can make a well put together proposal to the bank. This will not be as cheap as a homeloan, but when you get planning, you can always refinance.
