Development watch

Guernsey properties where a sale in the States of Guernsey property 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. 1,925 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 a ~25% Channel Islands premium — a rough guide only, not a quote, and not stated by the applicant.
