Thanks for the encouragement guys!
Well, OH has been to see the planning department today. They are applying both the function and finance test from PPS7.
The planning bloke thought we would find it difficult to meet the requirements of the finance test with just 9 acres, but the most important challenge is providing a 'watertight case' for needing to live on site.
The good news is that he said that the building itself would have very, very little impact on the surrounding area, so a design and access statement would be nothing more than a formality. So if we can get through the finance and function tests he said it wouldn't fail on design or situation.
Any advice on the function test? So far I'm saying that we need to be there to ensure that our animals require 24 hour care - but apparently there are animals that, in the eyes of planners, 'need' more round the clock care than others - is this correct? There is a really bad predator problem round there too (mostly foxes). We were actually going to get a couple of alpacas as part of the anti-fox strategy, but I worry that they'll think we're playing the alpaca card as a shortcut. Does anyone know of anyone who has had success with the function test? - if so, what case did they put forward?
