Hello and welcome to the site from an exliled Durham,
Yes, I understand your problem with the wind up in Lanchester. That's quite a descent size plot to get to grips with so I suggest you take it easy little by little, I planned and laid out my plot last year with shallow raised beds on my 9x5 mtr plot, I don't know what you are considering but raised beds are very easy to manager, mine are 10'x4' running north to south which for runners and french beans seems to be the natural way to maximise the sunshine ( all morning on one side of the line of poles and the rest of the day on the otherside), if I'd had more room I feel that the bed width could be wider maybe about 5 feet, I think if i had a similar sized plot as yours I would have a mix of raised and traditional beds, potatoes definately don't sit well in raised beds. Regarding the wind issue maybe you could consider a line of soft fruit bushes like raspberries along the prevailing border which would give a measure of windbreak, our site isn't to bad for wind but it did whip up a bit in May June last year so I invested in some debris netting from scaffold suppliers (on-line) and built wind breaks were required. I also use it as netting over my beds and it works great, it's extremely reasonabley priced when compaired to most horticultural options. Well, I hope I haven't rambled on too long and maybe you could pick up some hints from what I've said, anyway best of luck I'm sure you'll get it sorted. Cheers
