What the development plan says about the land on the Isle of Man
A listing gives you a price. It does not tell you the house is on the protected register, that the garden is inside a Conservation Area, or that the field behind has already been spoken for by the plan. 2,400 designations from the island's own published planning layers — 697 area plan sites, 19 planning conservation areas, 1,268 registered tree areas and more — matched against 516 listings currently on the market.

Matching is by map pin against the published boundary, so it is a strong indication and not a legal determination — a pin sits somewhere on a plot, not on its edges. Listings whose agents share a single parish-centre pin are left out entirely, because a shared coordinate cannot support a claim about one building.
