La Grande Route de Mont a L'abbe, St. Helier, St Helier
Description
Small private country estate of 10 acres Long carriage driveway Heated pool and perfect tennis court Ample garaging and additional parking FREEHOLD - SOLE AGENT - This amazing house has it all - privacy, a long sweeping drive, tennis court, swimming pool, lots of garaging, scope to extend and land!! A beautiful 4 bedroom country estate sits at the end of a new and very long carriage drive and is surrounded by its own land. The house has a lovely open aspect and offers immense privacy, yet it is surprisingly close to the town centre, schools and colleges are no more than a 5-minute car journey. Internally, some parts of the property require updating, however there is great potential to extend and create something amazing. The current property measures circa 4,259 sq.ft and offers 4 reception rooms downstairs and cloakroom with a utility room, whilst upstairs there 2 en-suite bedrooms, 2 additional double bedrooms and house bathroom. There is an all-weather tennis court as well as a heated swimming pool, beautiful gardens, orchard, agricultural land and paddock covering approximately 10 acres. The current owner is a avid car collector and surplus garaging for up to 9 cars next to the swimming pool could easily be converted into a pool house with guest accommodation if required. In terms of absolute privacy, Mont a L'abbe Farm is one of the best value estates on the Island.

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.
Price per square metre
£3,999,000 over 395.7 m² is £10,106 per m². Compared with other properties currently for sale that publish a floor area — the percentage is this property against that group's midpoint:
Floor area is parsed from the agent's own listing text (a stated size, or a figure mentioned in the description) — jersey's data carries no dedicated floor-area field, so coverage is partial. Comparisons are drawn from asking prices of properties currently for sale that publish a floor area, not achieved sale prices — the Places.je register records no floor areas at all, so a sold £/m² cannot be calculated from it. Sample sizes are shown in brackets; small groups move a lot. This is context for a conversation with an agent, not a valuation.
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?

Value added is the extra floor area priced at £6,818/m² — the midpoint asking price per m² among 219 St Helier 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.
