Sandy Island
Overview & Key Facts
Sandy Island is unlike any other development in Singapore’s property landscape. Situated on an actual private island within Sentosa Cove’s South Cove enclave, this collection of 18 ultra-luxury waterfront villas was conceived by Italian minimalist architect Claudio Silvestrin and landscape designer Jamie Durie as a “tropical island oasis” — a resort compound sealed from the wider city by water on all sides. Each villa spans approximately 700 m² (7,307–7,774 sqft) across four storeys, commands a private yacht berth accommodating vessels up to 12 metres, and delivers a private swimming pool, car lift, passenger lift, and waterfront gardens within an island that covers 17,000 m² in total. The development won the Prix d’Excellence Gold Award for Best Housing (Low Rise) worldwide in 2013 and the Southeast Asia Property Award for Best Housing Development and Best Architectural Design in 2011.
With only 4 recorded sales transactions in the URA caveat database and an average transacted price of S$10.6 million, Sandy Island occupies the extreme upper end of Singapore’s residential market. Transaction volumes are structurally thin: 18 total villas, long owner-occupier hold periods, and an ultra-high price quantum ensure that any given year may see zero or one transaction. Pricing evidence from public caveats confirms the range of roughly S$1,270–S$1,412 psf on land area in 2022–2023. A 2022 listing cited a guide price of S$11 million (S$1,415 psf on land), while the same unit had originally transacted at S$17.8 million in June 2013 (S$2,290 psf) — underscoring the significant capital erosion that Sentosa Cove landed properties experienced post-GFC through the 2015–2023 period. The investment case here is emphatically lifestyle and prestige ownership, not capital growth or rental yield.
Location & Connectivity
Sandy Island occupies the South Cove precinct of Sentosa Cove, Singapore’s only master-planned luxury waterfront marina district. Sentosa Cove itself sits on the south-western tip of Sentosa island, a 500-hectare resort island connected to the mainland via the Sentosa Gateway road causeway and the Sentosa Express monorail from VivoCity. South Cove — where Sandy Island is located — is the more exclusive, lower-density sub-precinct within Sentosa Cove, positioned along the waterfront facing the Java Sea.
Getting to and from Sandy Island requires either: (a) driving via the Sentosa Gateway / West Coast Highway corridor to the Sentosa island road network and into Sentosa Cove, or (b) arriving by private boat directly to the villa’s own berth. The nearest public transport interchange is HarbourFront MRT (NE1/CC29), approximately 3–4 km by road — a 10–15 minute drive in normal traffic conditions. The Sentosa Express monorail (VivoCity to Sentosa island) stops at Beach, Waterfront, and Imbiah stations; none of these stations serve Sentosa Cove directly, and a further taxi, Grab, or internal shuttle is required from the Sentosa island stations to Sandy Island. Door-to-CBD travel time (e.g., Raffles Place) is typically 25–35 minutes by car and 50–65 minutes via mixed public transport. All residents here drive or arrange private transport as a primary mode; this is not a lifestyle compatible with car-free or transit-first living.
Day-to-day amenities are clustered outside the Sentosa Cove boundary. VivoCity (Singapore’s largest mall by net lettable area) is the primary shopping and supermarket destination, approximately 10–15 minutes by car. The Resorts World Sentosa complex — Universal Studios, S.E.A. Aquarium, hotels, and F&B — is accessible within Sentosa itself. One°15 Marina, one of the premier marina clubs in Southeast Asia with 270 wet berths including 13 mega-yacht berths, forms the social and yachting hub of the Sentosa Cove community and is accessible by water directly from Sandy Island’s berths. The Sentosa Golf Club (Tanjong and Serapong courses) and the Quayside Isle restaurant enclave within Sentosa Cove provide further lifestyle amenities within the precinct.
Sentosa Cove’s Greater Southern Waterfront context is relevant to medium-term buyers: the URA’s Greater Southern Waterfront masterplan envisions transforming the Pasir Panjang, HarbourFront, and southern coastal corridor over the next 20–30 years, with potential uplift for Sentosa’s accessibility and tourism appeal. No firm timelines for Sentosa-specific enhancements have been gazetted, but the broader masterplan represents a structural tailwind for the precinct over a long hold horizon.
Facilities
Sandy Island’s facility proposition is fundamentally villa-by-villa rather than resort-block amenity. Each of the 18 villas contains its own private infinity-edge swimming pool, a private yacht berth for vessels up to 12 metres, a passenger lift connecting basement to the upper floors, a dedicated car lift (allowing direct basement parking), a gourmet dry and wet kitchen equipped with Miele appliances, and landscaped waterfront gardens designed by Jamie Durie. The villas are finished in natural stone and timber with double-height facades reaching 10 metres, four different layout configurations across the 18 units, and four to five ensuite bedrooms in standard configurations (with some resale units marketed at 7 bedrooms after basement conversion). Outdoor living is central to the concept: each villa’s waterfront garden merges the pool deck with the berth-side terrace, creating an uninterrupted indoor-outdoor flow that exploits the island setting.
As an island-format landed development, Sandy Island does not share conventional condominium communal facilities (no shared gym, shared tennis court, or club lounge). The estate does maintain shared security and landscaping for the 17,000 m² island as a whole, and residents benefit from Sentosa Cove’s precinct-wide 24-hour security and gated access. For club-level social facilities — dining, pool, gym, marina club membership — residents typically subscribe to the One°15 Marina Club at Sentosa Cove, which offers world-class marina facilities including the Singapore Yacht Show venue berths. The club-membership model suits the owner profile here: ultra-HNW individuals who prefer exclusive club-level amenities over shared condo common facilities.
“The berth is what makes Sandy Island genuinely different from anything else in Singapore. You can dock your boat at your own home, walk through the garden and be in your living room. No marina queue, no call ahead — just your boat, your berth, your home. For people who actually sail or have a yacht, there is nothing else like it in Singapore.”

Neighbourhood Comparison
Sandy Island is a landed villa development and does not compete directly against the condominium projects that form the broader District 4 market. However, contextual comparisons illustrate its position:
- Reflections at Keppel Bay — S$1,736 psf, 99yr, 1,129 units: landmark Daniel Libeskind-designed mixed development on mainland Keppel Bay, full facilities, walk to Harbourfront MRT feasible, deep liquidity. Mainstream CCR luxury condo profile.
- Caribbean at Keppel Bay — S$1,762 psf, 99yr, 969 units: waterfront condo on mainland Keppel Bay, full resort facilities, marina club access. High-liquidity CCR alternative to Sentosa landed.
- The Reef at King’s Dock — S$2,468 psf, 99yr, 429 units: newer development (2025 TOP) with closest mainland waterfront positioning to Sentosa Cove; premium PSF reflects recency and location.
- Cape Royale — S$2,220 psf, 99yr, 302 units: within Sentosa Cove itself; closest strata condo comparator. Has full condominium amenities, direct Sentosa Cove location, but no private berths and apartment-format living.
- Sentosa Cove landed comparators (The Cove, The Green Collection, Ocean Drive): same 99-year Sentosa leasehold structure, similar ultra-luxury specification, some with private berths. Competing directly for the same buyer profile but without Sandy Island’s architectural distinctiveness or island-within-island privacy.
Against the D4 condominium cohort, Sandy Island occupies a completely separate segment: the per-villa absolute pricing (S$10–17M) is 5–10× higher than a typical D4 unit at S$1.5–2.5M. The PSF comparison on land area (S$1,270–1,412 psf) actually appears modest relative to mainland D4 condos, but the appropriate comparison metric for landed villas is total price and lifestyle utility rather than PSF, which is most meaningful for apartment comparisons. The 2013 purchase prices of S$17–25M+ represent the benchmark investors compare current asking prices against — and the persistent gap explains the reluctance of long-tenured owners to sell at current levels.
| Development | Tenure | TOP | Units | ~Avg PSF |
|---|---|---|---|---|
| SANDY ISLAND | 99 yrs lease commencing from 2007 | 2013 | 18 | — |
| REFLECTIONS AT KEPPEL BAY | 99 yrs lease commencing from 2006 | 2011 | 1,129 | $1,736 |
| THE INTERLACE | 99 yrs lease commencing from 2009 | 2013 | 1,040 | $1,468 |
| CARIBBEAN AT KEPPEL BAY | 99 yrs lease commencing from 1999 | 2004 | 969 | $1,762 |
| THE REEF AT KING'S DOCK | 99 yrs lease commencing from 2021 | 2021 | 429 | $2,468 |
| CAPE ROYALE | 99 yrs lease commencing from 2008 | 2013 | 302 | $2,220 |
Lease Decay Analysis
The 99-year lease runs from 2007, meaning approximately 19 years have already been consumed. Roughly 80 years remain — still comfortably within the range where most banks will offer full financing without restrictions.
| Year | Lease remaining | Implication |
|---|---|---|
| 2026 (now) | ~80 years | Full bank financing available |
| 2037 | ~69 years | CPF usage still unrestricted for most buyers |
| 2046 | ~59 years | Approaching 60-year threshold — CPF limits begin for some |
| 2066 | ~39 years | Significant financing restrictions for next buyer |
| 2106 | Expiry | Lease reverts to state |
For a buyer purchasing today with a 10-year horizon (exit around 2036), the lease situation is essentially a non-issue — you’d be selling a property with ~70 years remaining, which is still very bankable. The risk profile changes for longer holds.

What Residents Say
“Sandy Island is the only address in Singapore where your boat is parked at your front door. I’ve owned property in Monaco, the Hamptons, and Sydney Harbour — Sandy Island is architecturally at that level. The Silvestrin minimalism, the stone and timber, the way every room frames the water. It is not a condo. It is a villa on a private island.”
— Ultra-HNWI owner-occupier on trophy property comparison via Stacked Homes — Sentosa Cove waterfront villa tour
“The island is completely private and the security is extremely thorough. We have 24-hour patrol boats as well as the land security. Unless you live here or are a registered guest, you simply cannot get onto Sandy Island. For families who value absolute security and privacy above all else — including prominent business families and high-profile individuals — that level of exclusion from the outside world is worth more than any gym or tennis court.”
— Long-term Sandy Island resident on security and privacy via YTL Land — Sandy Island
“The one honest thing I tell prospective buyers is: do you actually use a boat? If the berth at your front door excites you, this is the best address in Singapore. If you’re a road commuter who will never use the berth, the car dependency and the exit market illiquidity make it a very expensive lifestyle choice with no meaningful investment upside at current prices. Sandy Island is for a specific type of person.”

Strengths & Weaknesses
- Genuine private island address within Sentosa Cove — the only development in Singapore where your home is on a discrete island within the marina precinct
- Private yacht berth (up to 12m) at each villa — dual road + water access; arrive home by private boat
- Award-winning architecture by Claudio Silvestrin (Prix d'Excellence Gold 2013, SEA Property Awards 2011) and landscape by Jamie Durie
- Each villa ~700 m² (7,307–7,774 sqft), private infinity pool, double-height 10m living space, passenger lift and car lift — trophy specification unmatched in Singapore strata market
- Extreme privacy and security — island perimeter security, patrol boats, gated access; effectively impossible to access uninvited
- Sentosa Cove neighbourhood prestige — Singapore's only master-planned luxury marina precinct; proximity to One°15 Marina Club, Quayside Isle, Sentosa Golf Club
- Foreign nationals (non-citizens/non-PRs) may purchase landed property at Sentosa Cove with SLA approval — unique exception to Singapore's mainland landed foreign ownership rules
- Greater Southern Waterfront masterplan — long-term structural tailwind for Sentosa Cove precinct value over 20–30 year horizon
- Current pricing represents significant discount to 2013 peak levels — buyers in 2026 acquire at S$1,270–1,412 psf vs 2013 high of S$2,290 psf on land area
- Zero competition for this product type in Singapore — no direct substitute exists for a private-island villa with its own yacht berth
- Walkability 0/100 — physical island with zero pedestrian connectivity to mainland Singapore; car ownership or private boat is non-negotiable
- No MRT access — nearest station (HarbourFront NE1/CC29) requires a 10–15 min drive; Sentosa Express monorail does not serve Sentosa Cove
- Extreme illiquidity — only 4 sales transactions recorded across the development's entire 13-year history; exit can take years at any price
- Capital erosion risk — typical Sandy Island villas transact 30–40% below 2013 launch/peak prices; no guarantee of recovery over any fixed horizon
- Gross yield 2.89% (avg S$30,333/month rent on S$10.6M avg price) — very thin return for an illiquid, high-management-complexity asset
- Foreign buyer ABSD 60% (as of June 2023) — has materially reduced the international buyer pool that historically sustained Sentosa Cove landed liquidity
- 75-year CPF cliff in ~2031 (5 years) — minimal practical impact at S$10M+ price quantum, but signals the lease decay trajectory
- 60-year lease cliff in ~2046 (20 years) — imposes hard 30-year loan cap for future buyers; will compress buyer pool at resale
- Ultra-niche buyer profile — only 18 villas; en-bloc (44/100 score) is theoretically possible but practically complex given small unit count and high per-unit value
- Day-to-day convenience requires driving — supermarkets, hawker centres, and routine errands all require a vehicle trip out of Sentosa
Verdict
Sandy Island is one of Singapore’s most distinctive and narrowly positioned residential assets. The combination of an actual island address, private yacht berths, award-winning architecture by Claudio Silvestrin, and the Sentosa Cove waterfront makes this a genuinely unique product with no direct comparator in the Singapore market. For the correct buyer profile — ultra-high-net-worth individuals who actually use a yacht or large boat, value extreme privacy, and approach the purchase as a lifestyle asset rather than an investment vehicle — Sandy Island delivers at a level no mainland Singapore development can replicate.
The investment caveats are equally clear and should not be minimised. Extreme illiquidity is the dominant risk: 4 sales transactions over the development’s entire history means there is effectively no market. A buyer who needs to exit within 3–5 years could face a multi-year wait for a willing buyer at any price. The 0/100 walkability score and complete car dependency make Sandy Island unsuitable for any lifestyle requiring convenient public transport access. The gross yield of 2.89% (S$30,333/month average rent on S$10.6M average price) is thin for a property of this illiquidity and management complexity; the six rental transactions on record suggest this is primarily an owner-occupier development with occasional tenancies at very high absolute rents. The 60% Additional Buyer’s Stamp Duty for foreign buyers (as of June 2023) has structurally reduced the international demand that historically drove Sentosa Cove bungalow liquidity, and recovery in the foreign buyer segment is contingent on future ABSD policy changes.
The ShiokNest composite score of 43/100 reflects this narrow applicability. Neighbourhood 9.5/10 recognises the unmatched exclusivity and prestige of the Sentosa Cove island address. Facilities 8.5/10 acknowledges that each villa’s private pool, private berth, and Claudio Silvestrin design standard represent best-in-class residential delivery. Unit layout 8.0/10 reflects the exceptional floor area, quality, and villa-scale interior volumes. Lease 7.5/10 captures the 80-year tenure — adequate for a 20–30 year hold horizon but with meaningful cliff events in 2031 (75yr) and 2046 (60yr) that must factor into underwriting. Value 4.5/10 reflects the near-zero rental yield, post-peak capital erosion from 2013 highs, and illiquid exit market. MRT access 1.5/10 captures the structural reality: this is a car/boat-only address with no walk-to-MRT option. Buyers who fit the specific profile should engage specialist agents and conduct independent professional valuations — the thin transaction base makes fair-value assessment genuinely difficult.
