Striking and characterful family home with magnificent sea views across 15 acres of land above Bonne Nuit Bay, on the North coast of Jersey. Traditional property with modern finish Elevated position on North coast headland Four substantial bedroom suites Outdoor entertaining space Two bedroom guest cottage Heated swimming pool and pool house Location The property is situated on the headland above Bonne Nuit Bay with distant views towards the other islands. St Helier is an easy fifteen minute drive while access to St Michael's or St George's schools are similar distances. There is a glorious cliff walk along the island's north coast which is perfect on a sunny day. Description Whilst trying to be acutely respectful to the original building, this complete refurbishment has produced a stunning and traditional, yet also strikingly modern execution and finish. The grounds too have been completed overhauled, with a heated lit swimming pool, mature woodlands and natural coastal headland. Electronically operated gates and magnificent exterior lighting design brings the granite facades and outdoor spaces to life with accent and ambient lighting around the property. The main house is magnificent in its own right and the DiCasa team were determined to retain its character. It’s far from what you would expect and contains the signature DiCasa colour palette of luxe nudes and taupe’s, complemented with rich dark oak wooden flooring and velvet carpets across this 4-bedroom suite mansion. The imposing hallway is refreshingly bright and modern but with exquisite traditional touches like the vintage radiator covers, which leads to an impressive walnut rail and wrought iron staircase. The rich dark flooring continues into a formal drawing room and large dining room, finished with luxurio…

Nearest match in each category, from a fixed list of Jersey amenities — not every pub, café or shop on the island, so treat this as a useful sample, not a complete picture. Distances are straight-line ("as the crow flies"), multiplied by 1.3 to approximate real road-network distance — this is an estimate, not turn-by-turn routing, and actual walking/driving routes may differ. Times assume constant average speeds appropriate to Jersey's roads and 40mph limits: walking 4.5 km/h, cycling 14 km/h, driving 30 km/h — not open-road speeds, and they don't account for traffic, parking or terrain.
What would this cost to buy?
A live estimate, not a quote — change any figure below and everything recalculates immediately. Stamp duty / Land Transaction Tax uses Jersey's own standard-residence bands (see buying property in Jersey for the full table and how share-transfer property differs); the mortgage side is a standard capital-and-interest repayment calculation, not an offer from any lender.
Getting connected
Jersey has two residential broadband providers: JT — the island's own former state telecom, now Jersey's full-fibre network builder — and Sure, which completed absorbing Airtel-Vodafone's Channel Islands customer base in September 2025 (Airtel-Vodafone no longer trades as a separate operator here). Jersey's copper phone network is largely already history: JT finished building an island-wide fibre-to-the-home network back in July 2018 and has been retiring copper ever since — well ahead of Guernsey, where the equivalent copper switch-off was still under way through 2026. Always confirm actual coverage and switch-over status at this specific address directly with JT or Sure before assuming.
What would improving it be worth?
Modelled for this property in St John, 793 m² of known floor area. Adjust build quality or size for this property
Value added is the extra floor area priced at £7,241/m² — the midpoint asking price per m² among 14 St John properties currently for sale that publish a floor area. Cost uses £4,000–£6,000/m² new build and £2,000–£4,000/m² refurbishment, depending on quality. Net is against the mid rate. The last column is how often Jersey actually approves that kind of application.
Unlike the value side of this table (priced from Jersey's own current asking prices), the £4k–6k new-build / £2k–4k refurbishment rates are carried across from guernseyproperties.gg, where they were supplied by that site's owner from local Guernsey experience — they have not been independently verified for Jersey, and construction costs plausibly differ between the islands. Treat the Cost and Net columns as an unverified placeholder until a Jersey-specific quantity surveyor's rate replaces them.

Two things it cannot see. First, it prices floor area at the local average rate — it doesn't know your plot, your roof, your outlook, or whether an extension is physically possible; nor whether your street has a ceiling price that no amount of extending beats. Second, the rate comes from asking prices of other properties currently for sale that state a floor area — a minority of Jersey's live stock, so treat the sample sizes shown as real limits, not decoration.
The obvious alternative method is worse, which is why it isn't used here: comparing a typical 3-bed with a typical 4-bed suggests a bedroom is worth far more than it actually is — a bigger bed-count usually means a bigger house on a bigger plot, so that figure measures the mix of what's for sale, not the value of adding a room.
Before spending anything, get a builder's quote and talk to an architect — the type-of-work approval rates show how often that kind of application actually succeeds.

Estimate the cost of work you're considering
No live planning permission is on file for this address, so there's nothing to price directly — pick the kind of work you're weighing up instead, using the same cost ranges this site applies to real Jersey planning applications.
The work type shown is inferred automatically from the wording of the planning application's own description — it isn't stated by the applicant. The base cost range comes from published UK national renovation/build-cost guides for that type of project, and a ~25% uplift has been added to reflect higher shipping/import and skilled-labour costs in the Channel Islands — this is an estimate, not a published index. These figures are indicative only, not a quote: actual cost depends on specification, finish, ground conditions and the contractor. For anything serious, get a quote from a local quantity surveyor or builder.
