What work is coming
Every Guernsey planning application that is waiting for a decision, or has been granted since 2025-08-01 and so has probably not been built yet. It is the island's consented building work, read forwards — and unlike house sales, it keeps arriving whether or not the market is moving.

The type of work is inferred automatically from the wording each applicant used, so a description that does not say what it is will be classified loosely — see the applications themselves for the original text. Costs are modelled from typical Guernsey build rates, and where a category is priced per square metre without a known floor area a typical dwelling size is assumed; those rows are marked. They are an order of magnitude, not a quote.
A permission is not a building. Guernsey permissions run for years and a good number lapse unbuilt, so nothing here should be read as work in progress or as a commitment by the applicant. This site takes no fee from any firm listed in its directories, and a firm appearing there is not an endorsement.
