Hi... many thanks for your replies!
The land was agricultural way back up until 1918, and belonged to the local farm which owns pretty much all of the surrounding land. Then it was purchased by a local waterworks company in order to bring a good supply of drinking water to the area. A very deep well was dug right down into the chalk, some 300ft deep and the water in it is fabulous even after all this time... the water extraction stopped in around 1986.
I have unearthed the foundations of the original pump house which show that the building was considerably larger than the one currently in situ... about 3 times bigger. This is because the water was brought up using a steam pump, which, along with the well, took up a lot of space. Then, after the 2nd World War, the old steam pump was removed, the building demolished and replaced by a smaller one and the system electrified, using an electro submersible pump... ( I have installed one of these into the well and it pumps around a gallon every 6 seconds or so and I was able to create a small pond area... it is a seemingly inexhausible supply!)
I noticed in yesterday's Sunday Times there was a property for sale which they state was previously an old pumping station... so I guess getting pp is not entirely impossible... and there are so many of these redundant buildings across the country, it would be a shame not to bring them back into some kind of use...but the problem I have is the Article 4 direction, which I believe councils use to prevent any future development as would normally be allowed with Class B properties...and that the only way to get around this problem would be for the secretary of state to override the direction... some LAs apply article 4s on practically every redundant/commercial property, as they don't want them to be developed for housing... but there is a huge need and brownfield sites are supposed to be made available... In my case, the Article 4 is apparently to 'preserve the open aspect of the area'...
Used properly, Art. 4s are a good thing, especially in conservation areas and SSSIs, etc... but this land is very ordinary... mixed residential/agricultural/light commercial, and surrounded by prairie sized fields, hardly any trees or hedgerows, (I hope to rectify this), and criss crossed by telegraph poles and larger electricity pylons and with a huge solar panel 'farm' directly opposite. There are two farms within 500m of my land and both have a large assortment of modern outbuildings... not very easy on the eye, so to single out my silo as encroachment of an open space would be crazy... The pump house itself is a small, ugly brick built block... it looks very much like a public convenience... the silo fits in much better with its surroundings and there are quite a few silos in the area, two of which are less than 500m away down the lane...
I am keeping my eye on an application less than 900m away, where someone has put it to build a pair of cottages ona similar parcel of land, using some redundant storage outbuildings as a footprint... this development will be in the coastal zone, indeed, several houses have been built in the (protected?) coastal zone in the last 20 years...(my land falls just outside of the zone)... so it will be very interesting to see what happens there...
I intednd to try and keep the planners onside, of course... and so far the communication with them has been verbal... I've had nothing in writing. I contacted a planning consultant who told me I am not obliged to seek retrospective permission until they have notified me in writing... but it feels like Russian roulette to carry on with the silo conversion, with a chance that I might be made to pull it all down again...
The planning consultant also advised that we go for a pre application thing... 'to see if permission is likely'... but as the silo is already in place, I wonder if this is just to make more money, as there will still be fees invoved, so wonder if I should just go straight in with the retrospective application...?
I just feel like a rabbit paralysed by the headlights at the moment... but I need to do something...
Many thanks again for you views...
Theda.
