One Rosyth
Overview & Key Facts
One Rosyth is a rare and intimate boutique condominium tucked along Rosyth Road in District 19, completed in 2011 by Mushrooms Realty Pte Ltd. With just 17 units on its compact land parcel, this development occupies the opposite end of the spectrum from the mega-condos that dominate Singapore’s private residential market — offering a genuinely private, low-density living experience that few larger developments can replicate.
What makes One Rosyth particularly unusual is its tenure: technically a 999-year leasehold commencing from 1886, the property sits in that rare category sometimes described as “quasi-freehold.” With approximately 860 years remaining on the ground lease, it functions in most practical respects like freehold land — but buyers and their financiers need to understand that CPF usage and bank financing rules treat it as leasehold, which has implications as the “remaining lease” clock ticks toward specific regulatory thresholds.
Situated at the heart of the Rosyth estate — one of the most school-dense residential pockets in Singapore — One Rosyth has attracted families drawn to its exceptional proximity to eight schools within less than a kilometre. Transaction volumes are understandably thin given the unit count, but the price trajectory tells an unambiguous story: PSF has climbed from $988 in year one to $1,622 over the past 12 months, a 64% appreciation that outpaces many larger, more liquid developments in the same sub-market.
Location & Connectivity
One Rosyth is located on Rosyth Road, nestled within the established landed and low-rise residential enclave between Kovan and Serangoon. The nearest MRT station is Kovan MRT (North-East Line) at approximately 1.29 km — a distance that should be characterised honestly as not walkable in Singapore’s climate and heat. Residents travelling to the MRT on a daily basis will require a bus, a bicycle, or a short car ride. Bus services along Upper Serangoon Road provide connections to Kovan and Serangoon MRT, but the walk to the nearest bus stop itself takes several minutes from the development.
Drivers, however, find the location considerably more practical. Upper Serangoon Road feeds into the CTE and PIE quickly, putting the CBD within approximately 20 minutes in off-peak conditions and Orchard Road within 25 minutes. Serangoon Gardens Village — one of Singapore’s most beloved suburban dining clusters — is barely three minutes by car, offering a wide range of hawker stalls, Western bistros, and specialty grocers. The NEX shopping mall at Serangoon MRT is about eight minutes away and provides a FairPrice Xtra, cinema, and substantial dining options.
Day-to-day errands are well-served by the surrounding neighbourhood. Kovan Market & Food Centre is accessible via a short bus ride, and the Heartland Mall at Kovan MRT provides a Sheng Siong supermarket and neighbourhood retail. For residents with children, the school cluster immediately surrounding One Rosyth is an extraordinary asset: eight schools fall within 0.91 km, making this one of the most concentrated school catchment zones available anywhere in District 19.

Facilities
As a 17-unit boutique development, One Rosyth offers the kind of facilities package that reflects its scale: functional essentials rather than resort-style extravagance. Residents can expect a swimming pool, a gym, and landscaped common areas — sufficient for day-to-day use but unlikely to satisfy anyone accustomed to the expansive clubhouses, tennis courts, and themed aquatic zones that Singapore’s mega-condominiums provide. Bookings, maintenance queues, and lift waiting times are effectively non-issues at this unit count, which is itself a form of facility advantage. The pool is genuinely yours, not shared with 1,100 neighbours.
“Very quiet and private. Pool to ourselves most of the time. No queuing for the gym, no booking hassles. It’s the opposite of living in a big condo, and honestly that’s exactly what we wanted.”

Buyers who prioritise facilities breadth — badminton courts, function rooms, multiple pools, concierge services — should look to larger developments nearby such as Affinity at Serangoon or The Florence Residences. One Rosyth’s appeal lies elsewhere: in exclusivity, quiet, and the sense of owning a slice of a genuinely private compound in the middle of a busy residential district. For the right buyer, the absence of crowds is the facility.
Unit Sizes & Layout
One Rosyth’s 17 units span a varied mix of configurations typical of a 2011-era boutique development. Unit sizes tend to be more generous than what the same budget would command in contemporary new launches, reflecting the vintage layout standards of that period before the industry shifted aggressively toward shoe-box and compact typologies. The development’s small size means that precise floor plan data is limited in public records, but transaction evidence — with median prices around $1.45 million — suggests a buyer profile purchasing mid-sized apartments rather than entry-level studios. Buyers should request full floor plans from the seller or agent, as the limited transaction history makes unit-type generalisation difficult.
Given the limited number of units and infrequent transaction history, prospective buyers should pay careful attention to the specific stack orientation and floor level of any unit they are considering. In a 17-unit development, the variance between units — whether facing Rosyth Road, the internal compound, or adjacent landed housing — has a proportionally larger effect on liveability and future resale value than in a large development where hundreds of comparable units exist. Engage a conveyancer early to review the strata title plan and confirm exact boundaries.

Rents range from $2,850 to $3,850 per month across 8 rental transactions. Current rental yield sits at approximately 2.9%.
Price Appreciation
From 2021 to 2025, the average PSF has appreciated by 64.2% (from $988 to $1,622 psf).
Neighbourhood Comparison
The most instructive comparison is against Affinity at Serangoon ($1,698 psf, 99-year lease from 2018, 1,012 units) and The Florence Residences ($1,745 psf, 99-year lease from 2018, 1,410 units). Both are newer, larger, better-connected by bus and road, and offer substantially richer facilities. Both are also on 99-year leasehold — meaning genuine lease decay over a 30-40 year holding horizon. One Rosyth’s 999-year tenure is the single most defensible structural advantage it holds over every competitor in the sub-market: the land does not depreciate in any meaningful timeframe. Buyers pricing a 25-year holding period should weight this accordingly.
Against Chuan Park ($2,596 psf, 99-year lease from 2024, 916 units), the PSF gap is 37% — a premium that buys MRT adjacency, brand-new finishings, and a fresh lease, but locks buyers into the 99-year depreciation clock from day one. Stacked Homes’ Kovan-Serangoon guide captures the area’s evolution well: the sub-market is transitioning from older 99-year stock toward higher-density new launches, which over time tends to compress pricing for older leasehold units while leaving quasi-freehold assets relatively insulated. For a buyer with a long time horizon and school-age children, One Rosyth’s combination of tenure quality and school positioning makes it a genuinely differentiated option in a sub-market increasingly dominated by new-launch pricing.
| Development | Tenure | TOP | Units | ~Avg PSF |
|---|---|---|---|---|
| ONE ROSYTH | 999 yrs lease commencing from 1886 | 2011 | 17 | $1,622 |
| CHUAN PARK | 99 yrs lease commencing from 2024 | 2024 | 916 | $2,596 |
| THE FLORENCE RESIDENCES | 99 yrs lease commencing from 2018 | 2021 | 1,410 | $1,745 |
| RIVERFRONT RESIDENCES | 99 yrs lease commencing from 2018 | 2021 | 1,451 | $1,588 |
| AFFINITY AT SERANGOON | 99 yrs lease commencing from 2018 | 2021 | 1,012 | $1,698 |
| SERANGOON GARDEN ESTATE | Freehold | 2021 | — | $1,736 |
Lease Decay Analysis
The 99-year lease runs from 2011, meaning approximately 15 years have already been consumed. Roughly 84 years remain — still comfortably within the range where most banks will offer full financing without restrictions.
| Year | Lease remaining | Implication |
|---|---|---|
| 2026 (now) | ~84 years | Full bank financing available |
| 2041 | ~69 years | CPF usage still unrestricted for most buyers |
| 2050 | ~59 years | Approaching 60-year threshold — CPF limits begin for some |
| 2070 | ~39 years | Significant financing restrictions for next buyer |
| 2110 | 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 ~74 years remaining, which is still very bankable. The risk profile changes for longer holds.

What Residents Say
“Love the exclusivity. We never feel crowded. The school run is incredibly easy — Yangzheng is literally around the corner. Best decision we made for our kids’ P1 registration.”
— Resident review via EdgeProp
“The MRT situation is the one honest weakness. We drive so it doesn’t affect us, but if you need to take public transport daily, factor in the extra time. Bus is fine, just not as convenient as having a station nearby.”
— Resident review via PropertyGuru
“Very peaceful neighbourhood. Surrounded by landed houses, so very little traffic noise. The Serangoon Gardens food scene is just a short drive away. For our lifestyle it’s perfect, but I can see it not working for someone who wants to be in the thick of things.”
— Resident review via 99.co
The consistent theme across resident feedback is a strong sense of community and privacy, offset by frank acknowledgment of the MRT gap. Residents who drive or cycle describe the location as ideal; MRT-dependent residents note the bus supplement adds 15-20 minutes each way to commutes. Families uniformly cite the school proximity as the dominant reason they chose the development, and those with children in the P1 balloting pipeline regard it as a strategic decision that has validated itself. Facilities are described as adequate rather than impressive, with residents noting that exclusivity compensates for breadth.
Strengths & Weaknesses
- 999-year quasi-freehold land — no meaningful lease decay in any investment horizon
- 8 schools within 0.91 km including Yangzheng (0.26 km) — exceptional P1 balloting address
- Boutique 17-unit exclusivity — pool, gym, and facilities effectively private
- PSF appreciated 64% from $988 to $1,622 over four observed years
- 30-45% PSF discount to area new launches (Chuan Park at $2,596 psf)
- Quiet landed-enclave surroundings — minimal traffic noise and high privacy
- Rosyth estate neighbourhood — established, mature, low-crime residential pocket
- Serangoon Gardens Village dining scene reachable in under 5 minutes by car
- No booking queues, maintenance hassles, or crowded shared facilities
- Kovan MRT at 1.29 km — not walkable; bus or car required for daily commuting
- Only one MRT station nearby (Kovan NEL) — no interchange or alternative line
- Minimal facilities — no tennis courts, function rooms, or resort-style amenities
- Gross yield of 2.9% below typical OCR 3.5-4% expectation
- Only 17 units — thin transaction history makes price trend data statistically fragile
- Limited unit variety — few comparable transactions to benchmark a fair offer price
- 999-yr leasehold treated as leasehold by CPF/banks (though remaining lease is ~860yr, well beyond any concern)
- Small development means MCST governance heavily influenced by a handful of owners
- No 24-hour concierge or guard house typically found in larger developments
Verdict
One Rosyth is a niche property that suits a specific buyer profile extremely well — and suits most buyers not at all. Its clearest case is for a family with school-age children who value school catchment proximity above almost all else, drive to work or can tolerate the Kovan bus connection, and prefer the quiet intimacy of a sub-20-unit development over the resort-amenity culture of the area’s larger condos. For that buyer, the combination of 999-year quasi-freehold land, an exceptional school cluster at the doorstep, and a PSF that still sits 30-45% below new-launch comparables in the same sub-market makes a coherent and defensible case.
The investment case is more complicated. Gross yield at 2.9% is underwhelming — below the 3.5-4% typically expected from OCR leasehold properties — reflecting the price appreciation that has outrun rental growth. The total transaction count of six sales means the price trend, while impressive on paper ($988 to $1,622 psf over four years), is statistically fragile. A single anomalous transaction can move the reported PSF materially in a development this small. Buyers using the PSF trend as a primary investment signal should weight it accordingly.
Against the area’s newer-launch alternatives, One Rosyth asks buyers to make an explicit trade: exchange MRT proximity, facilities, and development freshness for land tenure quality, school proximity, privacy, and a meaningful PSF discount. Chuan Park at $2,596 psf offers a fresh 99-year lease, 916 units of neighbour activity, and MRT adjacency. The Florence Residences at $1,745 psf offers a larger community and better connectivity. One Rosyth at $1,622 psf offers none of those things — but offers something those developments cannot: a boutique compound with near-permanent land tenure in the heart of Singapore’s most school-dense residential enclave.
