Development watch

Isle of Man properties where a sale in the Isle of Man Land Registry's transaction register was followed, in the same year or a later one, by a planning application in this site's planning dataset (see /planning for its current coverage window) — a pattern consistent with someone buying a property, getting permission to develop it, and in some cases reselling it. This is inferred purely by matching addresses and dates across two public registers; there is no applicant name in this data, so it can never confirm who applied for permission or whether they are a professional developer. The "Likely developer" flag is a further guess, based only on whether the application's own wording implies more than one resulting home (multiple dwellings/apartments/flats, or "residential development") — a single-house rebuild or extension is tagged "Renovation/extension scale" instead. Treat every row here as a lead worth checking, not a confirmed fact. 4,777 matched applications on file.

Each row's estimated cost of works is inferred automatically from its own description text, using published UK renovation/build-cost guides plus the 18% Isle of Man uplift measured by AtkinsRealis for the Treasury in July 2026 — a rough guide only, excluding VAT and professional fees, not a quote, and not stated by the applicant.
