The Sierra
Overview & Key Facts
The Sierra is a small, boutique 60-unit freehold-adjacent leasehold development tucked along Mount Sinai Drive in District 10, one of Singapore’s most prestigious residential postcodes. Developed by Kohs Brothers Development and completed in 1998, it sits in the quiet enclave between Holland Road and the Ulu Pandan Park Connector — a pocket dominated by landed housing and mature private condominiums.
The defining characteristic of The Sierra is not its architecture or amenities — both are modest by modern standards — but its lease position. The development sits on a parcel with an original 99-year lease commencing in 1937, leaving roughly a decade of tenure at the time of writing. This single fact reshapes every conversation about the property, from financing to exit strategy to who the right buyer actually is.
For context, the broader Mount Sinai / Holland micro-market is anchored by newer developments like Leedon Green, D’Leedon, and Hyll on Holland, which transact in the S$2,600–2,900 psf range. The Sierra’s recent 12-month average of S$1,869 psf looks superficially cheap until you adjust for the lease — at which point the picture becomes considerably more nuanced.
Location & Connectivity
Mount Sinai Drive is one of those quintessentially District 10 addresses: prestigious on paper, but not especially well-served by public transport. Dover MRT on the East-West Line is the nearest station at roughly 760 metres, which most residents will find just beyond a comfortable daily walk in Singapore’s climate. Buona Vista MRT interchange (East-West and Circle Lines) is a short drive or a feeder bus ride away.
For drivers, the location is genuinely excellent. Holland Road, Commonwealth Avenue West, and the AYE are all minutes away, putting the CBD within a 15-minute off-peak drive and Orchard Road under 12 minutes. The one-north and Buona Vista employment cluster — home to biomedical, tech, and media tenants — is practically next door, which explains much of the consistent rental demand the area enjoys.
Daily conveniences lean on Rochester Mall, Holland Village, and the shops at Star Vista. For groceries and hawker food, Ghim Moh Market & Food Centre is a short drive away and remains one of the better old-school hawker centres on the west side. The Ulu Pandan Park Connector, running along the canal just north of the development, is a genuine quality-of-life asset for joggers, cyclists, and dog walkers.

Facilities
The Sierra is not a facilities-led development. With only 60 units and a compact footprint, the common areas follow the 1990s boutique-condo playbook: a standard swimming pool, a modest gym, a children’s play corner, a BBQ pavilion, and landscaped gardens. There is no tennis court, no function hall worth booking out, no themed lifestyle zones. What you get is what a mid-1990s architect thought a small prestigious condo should offer — and not much more.
That said, the low unit count is itself a form of amenity. Pool crowding is rarely an issue, lift waits are non-existent, and the community is small enough that most residents recognise their neighbours. For buyers coming from a larger mega-development, the trade-off is tangible: fewer facilities, but also fewer people competing for them.
The finishes reflect the development’s age. Original bathrooms, kitchens, and common-area fittings will show their vintage unless units have been renovated. Landscaping is well-maintained but not especially lush by modern standards. Buyers intending to own-stay should budget for a meaningful interior refresh — though with a short remaining lease, the economics of heavy renovation are worth careful thought.
Unit Sizes & Layout
With 60 units across a compact site, The Sierra’s unit mix is limited but generous. Layouts lean toward the larger configurations typical of 1990s District 10 developments — 3-bedroom and 4-bedroom apartments dominate, with generous living and dining footprints by contemporary standards. Ceiling heights, balcony depth, and utility-room provision all reflect an era when developers were not squeezing floor efficiency to the last square foot.
Transaction data over the last 12 months shows an average unit sale price of S$1,664,831 with a median of S$1,715,000 — figures that imply genuinely spacious layouts once you back out the ~S$1,869 psf average. For comparison, a 900+ sqft unit at this psf sits around the S$1.7M mark, consistent with the transaction pattern.
The caveat throughout is lease. A spacious freehold-feeling 3-bedroom in D10 for under S$2M sounds compelling until you realise the lease clock reads around a decade remaining. Renovation spend, financing tenure, and resale math all need to be framed through that lens.
| Bedrooms | Transactions | Avg PSF | Avg Price |
|---|---|---|---|
| 1 BR | 3 | $1,805 | $1,204,267 |
| 3 BR | 10 | $1,663 | $1,803,000 |
Pricing & Market Position
Based on 13 recorded transactions, sale prices range from $1,120,000 to $2,215,000, averaging $1,664,831 (~$1,827 psf).
Rents range from $2,350 to $12,000 per month across 92 rental transactions. Current rental yield sits at approximately 2.5%.
Price Appreciation
From 2021 to 2025, the average PSF has appreciated by 29.9% (from $1,439 to $1,869 psf).
Neighbourhood Comparison
Direct comparisons are instructive. D’Leedon (99-year lease from 2010, 1,703 units) transacts at around S$1,855 psf — effectively the same psf as The Sierra, but with 75+ years of remaining lease, full-spectrum facilities, and MRT-adjacency at Farrer Road. On a lease-adjusted basis, D’Leedon is dramatically better value for a long-horizon buyer. Leedon Green (freehold, 638 units) sits at S$2,784 psf — a 50% premium that buys permanent tenure and a fresh development.
Hyll on Holland (freehold, 319 units) at S$2,648 psf occupies the same trade-off zone. Fourth Avenue Residences (99-year lease from 2018, 476 units) at S$2,465 psf offers newer construction and a fresh 99-year runway near Sixth Avenue MRT. Skye at Holland at S$2,945 psf is the premium leasehold option with a 2024 lease.
The Sierra’s position in this comparison set is unambiguous: it is the cheapest D10 entry by a wide margin on headline psf, but the cheapest because of, not despite, its lease position. Buyers who correctly price short-lease risk can find genuine value here. Buyers who assume the psf gap is an arbitrage opportunity without adjusting for lease will almost certainly be disappointed on exit.

Lease Decay Analysis
The 99-year lease runs from 1937, meaning approximately 89 years have already been consumed. Roughly 10 years remain.
| Year | Lease remaining | Implication |
|---|---|---|
| 2026 (now) | ~10 years | CPF restrictions may apply |
| 2036 | Expiry | Lease reverts to state |

What Residents Say
Public resident commentary on The Sierra is sparse — a function of its small 60-unit size and low transaction turnover. Reviews on major portals are limited, but the consistent themes from the broader Mount Sinai / Holland landed-adjacent micro-market apply: residents value the quiet, the landed-enclave feel, and the proximity to top primary schools and international schools. Complaints cluster around dated finishes and the absence of the facility breadth that newer mega-developments offer.
“Very quiet street, and the park connector is right there. You forget you’re five minutes from Holland V.”

Tenant demand is notably steadier than buyer demand — the 91 rental transactions recorded against just 13 sales over the reference window tells its own story. Expat families cycling through UWCSEA Dover, Dover Court, and the Australian International School keep the rental market healthy, and the median rent of S$3,600/month on a 3-bedroom is competitive for the postcode. Gross yield sits at around 2.5%, which is on the low side but consistent with D10 averages.
Strengths & Weaknesses
- Prestigious District 10 address at an accessible absolute price point
- Generous 1990s unit layouts — larger than modern equivalents
- Dense education cluster within 1.5 km (Henry Park, ACS(I), UWCSEA, Dover Court)
- Quiet landed-adjacent setting with Ulu Pandan Park Connector access
- Strong drive access to CBD, one-north, and Orchard Road
- Boutique 60-unit community — uncrowded facilities, low density
- Healthy rental demand from expat families (91 rentals vs 13 sales window)
- En-bloc score 79/100 — meaningful collective-sale optionality
- Significant psf discount vs surrounding new launches and freeholds
- Critically short remaining lease (~10 years) — dominant risk factor
- CPF usage restricted on short-lease properties; bank tenures compressed
- Gross yield ~2.5% — below Singapore private residential average
- Dover MRT ~760m — not comfortably walkable in Singapore weather
- Modest facilities typical of 1990s boutique developments
- Dated finishes — meaningful renovation needed, economics are tight
- Resale pool narrows each year as lease decays
- Low transaction volume (13 sales/12m) — illiquid exit
- En-bloc is optionality, not certainty — no guaranteed outcome
Verdict
The Sierra is an unusual and specific proposition. On the surface, it offers what many buyers want: a quiet District 10 address, spacious 1990s layouts, a strong education cluster, decent drive access to the CBD and one-north, and a headline psf that looks cheap against surrounding new launches. On closer inspection, it is a leasehold property nearing the end of its runway — with roughly ten years of remaining tenure at time of writing — and that single variable dominates the analysis.
For own-stay buyers with a clear, bounded time horizon — think empty-nesters downsizing for 5–8 years, or expats on defined postings who would otherwise rent — the proposition can work. The acquisition cost is low in absolute terms for D10, the space is generous, and the location is genuinely good. For buyers of this profile, the short lease is a feature, not a bug: it prices the asset below comparable freehold alternatives.
For conventional buyers thinking in 20-year horizons, or anyone relying on standard bank financing, the calculus is much tighter. CPF usage is restricted on properties with sub-60-year remaining leases, bank loan tenures shrink sharply, and the resale pool narrows each year as the lease runs down. The en-bloc score of 79/100 hints at the obvious question — collective sale — but en-bloc outcomes are never guaranteed, and waiting for one is a strategy, not a plan.
