If.....

Remove two massive leylandii hedges from the boarder of the veg area, replace the long one bordering the neighbours to the south with a low hedge or fence, (maybe 3-4' rather that 8-9' weve currently got), the shorter length separating the lawn from the veg patch is to be replaced with a fence ( to keep the screen for my wifes sensibilities) and plant up the west side with cordon fruit trees, the east side I will probably plant up with mixed soft fruit from cuttings we've got available, sonprobably gooseberry and raspberries.
That should sort out the money available no problem, after that I'm considering a potager garden with raised beds and gravel paths but I'd need a further windfall for that I reckon.
