If there is a single address in Singapore that functions as the ultimate benchmark for residential prestige, it is Nassim Park. Tucked inside District 10, at the confluence of Nassim Road, Nassim Hill, and the fringe of the Botanic Gardens UNESCO World Heritage corridor, this gazetted Good Class Bungalow Area (GCBA) sits at the very apex of Singapore’s landed property hierarchy. Properties here are not merely expensive — they are structurally irreplaceable. (as of 2026-05) The gazette that protects Nassim Park has been in place since 1980, and the total number of qualifying GCBs within the enclave has not increased by a single unit since. In a land-scarce city-state where every square foot of freehold soil is contested, Nassim Park occupies a category of its own: a precinct where transactions routinely cross S$50 million, where foreign billionaires have negotiated Singapore citizenship specifically to gain purchase rights, and where the land itself — not the building on it — is the asset. Understanding Nassim Park requires more than a price chart; it demands a rigorous grasp of the planning rules, the ownership restrictions, the lifestyle covenant, and the ultra-thin liquidity that simultaneously protects and constrains everyone in this market.
Singapore’s Urban Redevelopment Authority (URA) gazetted 39 Good Class Bungalow Areas island-wide in 1980, permanently ring-fencing established enclaves of large detached bungalows from subdivision or redevelopment into higher-density housing. Nassim Park is among the most tightly concentrated of these areas and sits inside District 10 — which accounts for 27 of the 39 GCBAs — adjacent to the Botanic Gardens, Tanglin Club, and the embassies and high commissions that line Nassim Road and its surrounds.
URA’s planning parameters for GCBs are deliberately restrictive and uniformly applied across all 39 areas. Every qualifying bungalow must occupy a minimum land area of 1,400 sqm (approximately 15,069 sq ft), maintain a minimum plot width of 18.5 m and a minimum depth of 30 m, and the total site coverage — including all covered structures, car porches, and ancillary buildings — cannot exceed 40% of the land area. Building height is restricted to two storeys above ground, with a single attic permitted. These parameters are non-negotiable for new development applications; existing non-compliant structures are tolerated under grandfather rights but cannot be rebuilt to a non-compliant footprint. Full planning guidelines are published on the URA Development Control portal.
What distinguishes Nassim Park from most other GCBAs is scale. While the island-wide GCBA average plot size hovers close to the 1,400 sqm minimum in several areas, many Nassim Park plots range from 2,000 sqm to well above 3,000 sqm, with a handful exceeding 5,000 sqm. This is a meaningful premium even within the rarified GCBA universe. A larger land parcel commands a higher absolute quantum, but it also reduces the addressable buyer pool to a thin stratum of ultra-high-net-worth principals — typically family offices, multi-generational wealth vehicles, or recently naturalised Singapore citizens deploying capital from China, Southeast Asia, or India.
Ownership eligibility is the defining constraint. Under the Residential Property Act (Cap. 274), foreigners and Singapore Permanent Residents are barred from purchasing landed residential property in gazetted GCB Areas without express approval from the Singapore Land Authority (SLA). In practice, such approvals for GCBAs are exceptionally rare. This restriction creates a citizenship premium: Nassim Park’s effective buyer pool is limited to Singapore citizens, a constraint that mechanically reduces transaction volume while simultaneously preventing distressed forced-sale price collapses typical of foreign-investor-dominated luxury markets. For a deeper analysis of ownership pathways, see Can Foreigners Own a GCB in Singapore? and the GCB & Ultra-Luxury Market Guide. For D10 market-wide context, consult District 10 Analytics.
Nassim Park is a gazetted Good Class Bungalow Area (GCBA) in District 10. GCBAs are Singapore's most exclusive residential zones — plots must be at least 1,400 sqm, capped at two storeys, and ownership is restricted to Singapore Citizens (Permanent Residents require an LDAU exception in rare cases).

Methodology
Transaction figures are sourced from URA REALIS caveats (typically 2-4 week lag). Plot-area threshold of 1,400 sqm is enforced per the URA gazette. Only Detached property types are counted; Strata Detached cluster homes within the GCBA are excluded. GCBA assignment uses our internal street→area gazetteer (view all 39 GCBAs).

- The most prestigious address in Singapore’s GCBA universe. Nassim Park is consistently cited alongside Nassim Road itself and Cluny Park as one of the three or four GCBAs that sit in a tier above the rest. The combination of location — adjacent to the Botanic Gardens, minutes from Orchard Road’s belt of five-star hotels, and surrounded by the diplomatic quarter — with plot scale and freehold tenure creates an address premium that no amount of redevelopment can manufacture elsewhere. For comparative positioning, see the Nassim Road GCB Area Profile and Cluny Park GCB Area Profile.
- Gazette-fixed supply with zero risk of dilution. Singapore’s 39 GCBAs are permanently closed to new additions. The total island-wide GCB count of approximately 2,800 units cannot increase; the gazette specifically prevents subdivision of existing plots and prohibits any development that would result in additional GCB-sized parcels. Nassim Park’s slice of that finite stock is among the most coveted. The structural supply ceiling is a scarcity moat that luxury condominiums — which can be built on new or redeveloped sites — simply do not possess.
- Dominant freehold and 999-year leasehold tenure. The overwhelming majority of Nassim Park titles are freehold or 999-year leasehold. In Singapore’s residential market, tenure is a primary value driver: freehold properties have historically commanded a 10–20% premium over 99-year leasehold equivalents, and there is no lease-decay discount eroding the asset over the holding period. The long-term capital preservation argument for a freehold GCB is materially stronger than for a leasehold condo. Explore the Tenure Price Trends analytics for the quantified premium across Districts 9 and 10.
- Embassy corridor and Botanic Gardens adjacency. Nassim Park borders one of Singapore’s most established diplomatic and institutional precincts. The proximity to the Singapore Botanic Gardens — the only UNESCO World Heritage Site in Singapore and one of the most carefully managed urban green spaces in Asia — delivers a greenery buffer, noise insulation, and a prestige adjacency that appreciates in symbolic value over time rather than depreciating. Embassies and high commissions on Nassim Road and its tributaries create a low-density, low-traffic residential character that is impossible to replicate on commercially active corridors.
- Connectivity to Orchard and CBD without sacrificing privacy. Despite its atmosphere of seclusion, Nassim Park sits within 5 km of the Orchard Road retail belt, 3 km from the Tanglin Mall and Gleneagles Hospital cluster, and roughly 7 km from Raffles Place. The Stevens MRT station (Downtown and Thomson-East Coast Lines) and the Napier MRT station (Thomson-East Coast Line) are within comfortable reach, providing direct rail access to Marina Bay, Woodlands, and the eastern corridor. Ultra-high-net-worth residents typically commute by car, but dual-line MRT accessibility reinforces Nassim Park’s long-term capital appeal to a broader resale market.
- International school catchment and family-office ecosystem. Tanglin Trust School (British curriculum, Portsdown Road), the Swiss School (Bukit Timah corridor), and the Hollandse School (Dutch international, Holland Road) are all within a 5 km radius. Singapore American School and Canadian International School operate shuttle networks that serve the Nassim–Tanglin corridor. This concentration of international schools is a primary demand driver for globally mobile ultra-high-net-worth families. The Singapore family-office ecosystem, which has grown rapidly since the Monetary Authority of Singapore’s Variable Capital Company (VCC) framework launched in 2020, adds institutional demand from family offices treating a Nassim Park GCB as the residential component of a broader Singapore wealth deployment. For strategy context, see Singapore Family Office Property Strategy.
- Entry quantum of S$40–120 million effectively gates the market to a handful of principals globally. Nassim Park is not expensive relative to comparable enclave addresses in London, Hong Kong, or Sydney — it is expensive in absolute dollar terms. The practical floor for a mid-sized GCB here is S$40 million; larger plots with good orientation exceed S$100 million. At these quantum levels, the global pool of citizens with both the liquidity and the Singapore citizenship required to transact is extraordinarily thin. In a global risk-off environment, this buyer pool can contract sharply, producing extended holding periods before a suitable buyer emerges at the seller’s target price.
- ABSD remains a friction even for Singapore citizens buying a second property. A Singapore citizen purchasing a second residential property pays 20% Additional Buyer’s Stamp Duty (ABSD) on the purchase price. On a S$60 million GCB, that is S$12 million in ABSD before accounting for Buyer’s Stamp Duty (BSD), legal fees, and agent commissions. Decoupling strategies can reduce ABSD exposure for couples, but the mechanics are complex and time-sensitive. Use the Stamp Duty Calculator to model the full acquisition cost at your target price, and review GCB Decoupling Strategy for ownership-structure planning. Citizens who own no other residential property pay zero ABSD on a first purchase — a significant incentive for those structuring a clean entry.
- Redevelopment cost and planning complexity are non-trivial. Rebuilding a Nassim Park GCB or undertaking major A&A (Additions and Alterations) work requires engagement of a Qualified Person (QP) architect, URA planning approval, and BCA permits. The 40% site coverage cap and the two-storey height restriction constrain maximisation of gross floor area, meaning the design premium for a Nassim Park rebuild is higher than for properties with fewer planning constraints. High-specification GCB construction in Singapore typically runs S$800–S$1,500 per square foot of built area; on a 3,000 sqm plot with a 40% coverage cap (1,200 sqm GFA at two storeys), that implies a build cost of S$10–25 million on top of land acquisition. For the regulatory framework, see GCB Redevelopment Rules.
- Illiquidity is structural, not cyclical. GCBs in general, and Nassim Park GCBs in particular, do not trade with the frequency of condominiums. The entire GCBA market transacts fewer than 300 properties per year island-wide; Nassim Park itself may see only 2–5 transactions in a given year. This illiquidity is partly what protects the price floor — motivated sellers are rare — but it also means that a forced sale, or a sale into a thin market, may require a discount to achieve a timely transaction. Buyers entering at peak market conditions with high leverage face genuine mark-to-market risk.
- Property tax on a S$50M+ residence is material and non-trivial. Singapore property tax is calculated on the Annual Value (AV) assessed by IRAS, not the market value, but IRAS adjusts AVs regularly to reflect rental market movements. A Nassim Park GCB with a monthly rental value assessed at S$30,000–S$80,000 generates an AV of S$360,000–S$960,000 annually. Owner-occupier property tax rates are progressive on AV; non-owner-occupier rates are higher. For a detailed breakdown, consult GCB Property Tax and use the Property Tax Calculator for a scenario-specific estimate.
- Policy risk cannot be priced out. Singapore has a track record of adjusting property cooling measures without market warning — the April 2023 ABSD hike for foreigners (to 60%) and for Singapore citizens buying second properties (from 12% to 20%) arrived on a Friday evening. Any future tightening of the citizenship-only rule, further ABSD increases for citizens, or changes to SLA’s approval criteria for PRs could directly compress demand at Nassim Park’s price tier. Buyers should factor in policy optionality when setting their holding-period expectations.

Nassim Park occupies a position in Singapore’s residential hierarchy that has no direct domestic peer. It is not simply the most expensive GCB area by median transacted price — it is the area where the greatest concentration of institutional-quality, large-plot, freehold GCBs has produced a multi-decade record of transactions that redefine the ceiling of Singapore’s residential market. The S$50–120 million price range is not inflated by a temporary demand spike; it reflects the permanent convergence of gazette-fixed supply, citizenship-gated ownership, and the global demand for a Singapore residential foothold from a growing class of ultra-high-net-worth families.
The structural investment thesis is unusually durable. Singapore’s fundamental advantages — rule of law, political stability, geographic and logistical centrality in Southeast Asia, and an increasingly deep family-office ecosystem — underpin demand for exactly the kind of asset that Nassim Park represents. The Monetary Authority of Singapore has actively positioned Singapore as Asia’s premier wealth management centre; that positioning draws the principal-class buyers who ultimately compete for Nassim Park GCBs. The gazette protection means this supply will not be diluted by additional development, and the citizenship-only rule means the buyer pool is insulated from the volatility of foreign speculative capital flows that periodically whipsaw other ultra-luxury markets.
The risks are real and specific: quantum gating that creates extended hold periods before a suitable buyer appears, material ABSD for citizens who already own residential property, redevelopment cost and planning complexity for buyers with a renovation intent, and the structural illiquidity of a market that transacts at single-digit annual volume. These are not hidden risks — they are inherent to the asset class — and buyers who enter Nassim Park with a realistic 10–20 year time horizon, adequate liquidity reserves, and no forced-sale constraint have historically been well served.

Frequently asked questions
What makes Nassim Park different from other GCB Areas in Singapore?
Nassim Park is distinguished from the other 38 gazetted GCB Areas primarily by three factors: location, plot scale, and transaction history. In terms of location, the area sits adjacent to the Botanic Gardens, within the diplomatic enclave of Nassim Road, and 5 km from both Orchard Road and the CBD — a combination that is structurally irreplicable. On plot scale, many Nassim Park land parcels range from 2,000 sqm to over 5,000 sqm, well above the statutory 1,400 sqm minimum and above the average plot size in most other GCBAs. And the area’s transaction record includes some of Singapore’s most notable headline deals, cementing its institutional-tier reputation. For comparison, see the Nassim Road GCB Area Profile and the GCB & Ultra-Luxury Market Guide.
What are the URA planning rules that apply to all Nassim Park GCBs?
Under URA’s Development Control guidelines for Good Class Bungalows, every qualifying property must meet a minimum land area of 1,400 sqm (approximately 15,069 sq ft), a minimum plot width of 18.5 m, and a minimum plot depth of 30 m. Total site coverage — including the main building, car porch, and all covered ancillary structures — cannot exceed 40% of the total land area. Building height is restricted to two storeys above ground, with an attic permitted subject to height and coverage controls. These rules prevent subdivision of existing plots and strictly limit intensification, which is why the total number of GCBs in Nassim Park has been essentially static since the gazette. Full parameters are published on the URA Development Control portal.
Can foreigners or Singapore PRs buy a GCB in Nassim Park?
In almost all cases, no. Under the Residential Property Act (Cap. 274), foreigners and Singapore Permanent Residents are barred from purchasing landed residential property in gazetted GCB Areas without express prior approval from the Singapore Land Authority (SLA). Such approvals for GCBA purchases are exceptionally rare in practice. The effective buyer pool for Nassim Park GCBs is therefore limited to Singapore citizens. Foreigners can legally rent a GCB in Nassim Park, and this market segment does produce high headline rents, but rental confers no capital ownership. See Can Foreigners Own a GCB in Singapore? for the full legal framework.
What price range should I expect for a Nassim Park GCB (as of 2026-05)?
Indicative market pricing (as of 2026-05) for Nassim Park GCBs ranges from approximately S$40–60 million for smaller plots (2,000–2,500 sqm), S$60–90 million for mid-tier plots (2,500–4,000 sqm), and above S$100 million for very large or highly prominent parcels. On a per-square-foot-of-land basis, indicative figures range from S$2,800 to S$4,500 psf depending on plot orientation, road frontage, proximity to the Botanic Gardens boundary, age of the existing structure, and overall presentation. Use the Total Acquisition Cost Calculator and Stamp Duty Calculator to model the all-in cost, including ABSD tiers applicable to your citizenship and ownership profile.
What are the ABSD implications for buying a GCB in Nassim Park?
Additional Buyer’s Stamp Duty (ABSD) is applied on the purchase price or market value, whichever is higher. For a Singapore citizen buying their first residential property: zero ABSD. For a citizen buying a second residential property: 20% ABSD. For a third or subsequent property: 30%. Singapore Permanent Residents pay 5% on a first purchase and 25% on a second. Foreigners pay 60% ABSD and also require SLA approval. On a S$70 million GCB, a citizen buying a second property would pay S$14 million in ABSD, plus approximately S$2.1 million in standard Buyer’s Stamp Duty — a total upfront cost of roughly S$86 million before financing. Use the Stamp Duty Calculator for a precise breakdown at your target price and ownership profile, and review the GCB Decoupling Strategy for ownership structuring options that may reduce ABSD exposure.
What is the typical rental income and gross yield on a Nassim Park GCB?
Nassim Park GCBs have achieved some of Singapore’s highest residential rental figures. Smaller, well-maintained GCBs in the area typically rent in the range of S$25,000–S$60,000 per month depending on built area, fit-out quality, and garden configuration. Larger, trophy-tier properties with exceptional specification can exceed S$100,000 per month in exceptional circumstances. At these rent levels relative to current capital values of S$40M+, gross rental yield is typically 0.5–1.5% — significantly below the 2.5–4% achievable on a CCR condo. Nassim Park is fundamentally a capital-appreciation and wealth-preservation asset, not a rental income vehicle. Use the Buy-to-Let Yield Calculator for scenario modelling.
How does rebuilding or renovating a Nassim Park GCB work?
Any new construction, demolition and rebuild, or substantial Additions and Alterations (A&A) work on a Nassim Park GCB requires engagement of a Singapore-registered Qualified Person (QP) architect, URA Written Permission (WP) for development, and Building and Construction Authority (BCA) approvals. The URA planning parameters (40% site coverage cap, two-storey height limit) constrain what can be built, and high-specification GCB construction typically costs S$800–S$1,500 per square foot of built area. On a 3,000 sqm plot, a full rebuild could add S$12–25 million on top of land cost. Heritage trees on the boundary or along Nassim Road may also require NParks clearance if affected by site works. See GCB Redevelopment Rules for the full planning workflow.
