Le Mont Gras D'Eau, St. Brelade, St Brelade
Description
St Brelade’s Bay has long been regarded as one of the most coveted addresses in Jersey, and Apartment 10 occupies a beautifully elevated position above the bay within Château des Roches. Developed in 1983 as the successor to the original 1870 residence, the Château was designed to embrace its remarkable coastal setting and capture the far-reaching southerly views that define this part of the island. This south-facing penthouse apartment sits on the top floor and enjoys panoramic vistas across the treetops to the bay beyond. The 25ft main reception room is a wonderfully bright and generous space, framed by those uninterrupted views, while the separate kitchen and adjoining utility room form a practical and well-considered everyday hub. The recently installed luxury kitchen adds a further layer of refinement. The master suite is approached via a lined ante room with extensive built-in wardrobes and enjoys a dual aspect to the south and west, drawing in both daylight and sea views. An en suite bathroom completes this peaceful retreat. A guest double bedroom, a further office/bedroom and a separate guest bathroom provide excellent flexibility, with a cloakroom located off the entrance hall. Storage has been thoughtfully integrated throughout, complemented by a private cellar/storage room on the communal ground floor. Apartment 10 also benefits from a generous double garage within the secure, gated basement parking atrium reserved for residents, with additional visitor parking on the impressive forecourt and its colonnaded entrance. Beautifully landscaped private gardens wrap around the southern side of the Château, offering calm and carefully tended spaces to enjoy. Mature trees to the south and woodland to the north ensure an exceptional sense of privacy, with neighbouring…

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
£1,350,000 over 126 m² is £10,714 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?
Every row assumes a house with its own roof and its own plot — a flat doesn't normally have exclusive control of either, so extensions, loft conversions and annexes aren't options in the way they are for a house, whatever the price-per-m² arithmetic might suggest. Treat this as not applicable to Le Mont Gras D'Eau, St. Brelade.

Estimated cost of live planning permissions
Jersey planning permissions lapse after a set period if unbuilt; these applications fall inside the last 3 years and were not refused, so they are presumptively still capable of being implemented.

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.
