I've just been given a valuation for my plot in Aberdeenshire - £70,000; with water, electricity, drainage all close by, and I am presently obtaining quotes for taking these onsite. About 1000 sq m, so plenty room for a 3 bed house (build cost about £150K), plus a large fertile plot containing some established trees for shelter. Wooden garage and railway meat carriage included. Adjacent to farmland, so neighbour might be willing to rent some more land.
PM me for details.
