Over the past two years, the River Valley and Great World enclave (District 09) has emerged as the epicentre of Singapore’s prime Core Central Region (CCR) urban renewal. Anchored by the fully operational Thomson-East Coast Line (TEL) at Great World MRT (TE15), a succession of Government Land Sales (GLS) tenders along the Singapore River has created an extraordinary cluster of luxury residential towers.
For homebuyers and high-net-worth investors, having five major contiguous parcels launched or prepared in close succession creates both unparalleled choice and analytical complexity. How do River Modern, River Green, Promenade Peak, and Zyon Grand compare in land costs, building scale, unit mix, and maintenance overheads? More importantly, where does the lowest entry price sit today for each bedroom configuration?
Drawing upon verified project filings and verified industry data (correct as of 11 October 2026), this comprehensive comparative guide breaks down the key facts, price floors, and strategic advantages across River Valley’s premier new developments.
1. Land Cost Benchmarks: From $1,202 to $1,730 PSF PPR
A developer’s land acquisition cost establishes the mathematical price floor beneath any project. In River Valley, intense institutional bidding across successive GLS tenders has pushed land baselines steadily upward.[2]
Understanding this progression reveals which developments locked in lower land cost bases and why upcoming sites will inevitably enter the market at higher price tiers:
Notably, Zyon Grand secured the lowest land rate in the cluster at $1,202 psf ppr, reflecting its master-development scale (incorporating serviced apartments and extensive retail). Meanwhile, River Modern was won by GuocoLand at $1,420 psf ppr, directly adjacent to Great World MRT. Looking forward, the upcoming River Valley Green (Parcel C) tender closed at a striking $1,730 psf ppr—a 22% jump over River Modern and a 44% jump over Zyon Grand—guaranteeing that subsequent launch pricing in the precinct will push well beyond current levels.
| Development | Developer / Consortium | Address | GLS Land Rate (PSF PPR) | Site Area (Sq Ft) |
|---|---|---|---|---|
| Zyon Grand | CDL & Mitsui Fudosan | 3 & 5 Kim Seng Road | $1,202 psf ppr | 164,449.95 sq ft |
| Promenade Peak | Allgreen Properties | 1 Zion Promenade | $1,304 psf ppr | 99,955.28 sq ft |
| River Green | Wing Tai | 11 River Valley Green | $1,325 psf ppr | 100,033.30 sq ft |
| River Modern | GuocoLand | 5 River Valley Green | $1,420 psf ppr | 126,326.30 sq ft |
| River Valley Green (Parcel C) | Upcoming Future Pipeline | River Valley Green | $1,730 psf ppr | Future Launch Benchmark |
2. Architectural Scale, Tower Heights & TOP Schedules
Each River Valley development presents a distinct architectural philosophy—ranging from super-tall skyscraper living to intimate mixed-use riverfront hubs.[1]
Reviewing the physical scale, unit counts, carpark ratios, and expected handover timelines helps buyers align project characteristics with their move-in horizon:
Buyers seeking soaring skyline views may gravitate toward Promenade Peak’s 63-storey single tower or Zyon Grand’s twin 62-storey towers. In contrast, River Modern by GuocoLand focuses on twin 36-storey luxury pavilions integrated with six ground-floor commercial shops and direct sheltered connection into Great World MRT, offering an 82% carpark provision.
| Development | Tower Configuration & Features | Total Units | Carpark Provision | Expected TOP | Vacant Possession |
|---|---|---|---|---|---|
| Promenade Peak | 1 Tower of 63 Storeys | 596 Units | 477 Lots (80%) | Q2 2030 | Q1 2031 |
| River Green | 1 Tower of 36 Storeys | 524 Units | 269 Lots (51%) | Q3 2029 | Q2 2030 |
| River Modern | 2 Towers of 36 Storeys + 6 Commercial Shops | 455 Units | 373 Lots (82%) | 2H 2030 | 31 Dec 2032 |
| Zyon Grand | 2 Towers of 62 Storeys + Serviced Apartments (22 F&B, Supermarket, ECDC) | 706 Units | 565 Lots (80%) | Q2 2030 | Q3 2032 |
3. Current Availability & Lowest Entry Prices (October 2026)
Unit availability across River Valley has tightened significantly following robust developer sales throughout 2026. Certain bedroom configurations have already completely sold out, while others present clear entry-level value opportunities.[1]
The table below compiles verified lowest available entry prices across all four major developments as of 11 October 2026:
Several critical market patterns emerge from this price audit. First, 1-bedroom and 1-bedroom + study units under $1.5 million are virtually restricted to River Green ($1,395,000 on #25-01), Zyon Grand ($1,453,000 on #32-11), and Promenade Peak ($1,462,300 on #02-06). River Modern deliberately excluded 1-bedroom units to preserve owner-occupier exclusivity.
Second, for 2-bedroom residences, River Modern offers the most competitive entry ticket at $1,863,000 (#29-05), outperforming River Green’s $2,163,000 and Promenade Peak’s $2,058,100, while Zyon Grand’s standard 2-bedroom inventory is 100% fully sold out.
| Unit Type | Promenade Peak | River Green | River Modern | Zyon Grand |
|---|---|---|---|---|
| 1-Bedroom | Unavailable | $1,395,000 (#25-01 · $3,321 psf) | Unavailable (No 1BRs) | Unavailable |

| 3-Bedroom | $3,212,700 (#34-12 · $3,110 psf) | $3,123,000 (#34-10 · $3,581 psf) | $3,375,000 (#34-04 · $3,733 psf) | $2,792,000 (#54-06 · $3,413 psf) |
| 3-Bedroom Premium | $4,059,000 (#44-12 · $3,261 psf) | FULLY SOLD | FULLY SOLD | FULLY SOLD |
| 4-Bedroom / Premium | $4,634,300 (#61-10 · $3,490 psf) | FULLY SOLD | $6,174,000 (#02-03 · $3,374 psf) | $5,395,000 (#44-08 · $3,341 psf) |
| 5-Bedroom Premium | $6,436,800 (#44-01 · $3,417 psf) | Unavailable | Unavailable | $6,018,000 (#44-01 · $3,308 psf) |
4. Maintenance Fees & Monthly Holding Cost Comparison
Ongoing holding costs represent an important factor for both owner-occupiers and rental investors. Maintenance fees reflect development facilities, landscaping scope, security staffing, and share value allocations.[1]
Estimated monthly maintenance fees across the developments are structured as follows:
Promenade Peak offers the most competitive entry-level maintenance rates starting from $325 per month for 1-bedroom study units, while River Green maintains a streamlined $350 to $420 bracket. River Modern and Zyon Grand carry slightly higher fee schedules ($422.50 to $737 monthly) reflecting extensive curated botanical grounds, on-site commercial facilities, and dedicated concierge provisions.
| Development | 1-Bedroom / Study | 2-Bedroom Types | 3-Bedroom Types | 4-Bedroom & 5-Bedroom Types |
|---|---|---|---|---|
| Promenade Peak | $325 / month | $390 / month | $390 – $455 / month | $455 – $520 / month |
| River Green | $350 / month | $350 – $420 / month | $420 / month | $420 / month |
| River Modern | Unavailable | $422.50 – $507.00 / month | $507.00 – $591.50 / month | $591.50 – $676.00 / month |
| Zyon Grand | $469 / month | $469 – $536 / month | $536 / month | $670 – $737 / month (PH to $938) |
5. Connectivity & Lifestyle: Great World MRT, Schools and River Promenade
All four developments share the extraordinary lifestyle advantages of the River Valley precinct, but their exact physical orientation offers distinctive strengths:[3][4]
1. Direct MRT Integration: Great World MRT Station (TE15) on the Thomson-East Coast Line connects residents directly to Orchard Boulevard (1 stop), Shenton Way and the Central Business District (4 stops), and Marina Bay (5 stops). River Modern and River Green sit on the doorstep of the station with direct sheltered access.
2. Integrated Retail & Dining: Great World City shopping mall provides over 400,000 sq ft of lifestyle shopping, Cold Storage, Meidi-Ya Japanese supermarket, Golden Village cinema, and extensive enrichment academies. Furthermore, Zyon Grand will introduce 22 F&B outlets, a supermarket, and an Early Childhood Development Centre directly on its podium grounds.
3. Primary School Catchment (<1km): River Valley Primary School sits within the coveted 1 km home-school distance for all four sites—a massive demand driver for local families seeking top-tier primary education. Alexandra Primary School and Zhangde Primary School also serve the immediate vicinity.
4. Singapore River PCN: Immediate access to the Singapore River Park Connector allows seamless jogging and cycling along the waterfront through Robertson Quay, Clarke Quay, and Boat Quay into Marina Bay.
6. Buyer Decision Matrix: Which River Valley Launch Fits You?
When choosing between these four premier launches, buyers should align their purchase decision with specific lifestyle objectives and capital profiles:
For Rental Investors Seeking Sub-$1.5M Quantum: Look closely at River Green (#25-01 at $1,395,000) or Zyon Grand (#32-11 at $1,453,000). High rental yields in Great World from tech and banking professionals ensure strong tenant demand.
For Discerning 2-Bedroom Owner-Occupiers: River Modern offers the most competitive 2-bedroom entry at $1,863,000, combined with GuocoLand’s signature landscaping, high carpark ratio (82%), and absence of high-turnover 1-bedroom units.
For Ultra-High-Floor Panoramic Luxury: Promenade Peak (63 storeys) and Zyon Grand (62 storeys) offer sky-high living above the 50th storey, delivering breathtaking unblocked vistas across the river and Orchard skyline.
For Long-Term Legacy Wealth Preservation: Buyers comparing 99-year leasehold new launches against prime 999-year legacy alternatives along the riverfront should evaluate The River Opus (Valley Point 999-year mixed redevelopment featuring 407 riverfront homes in Legacy & Sky Villa collections, launching Feb 2027) as well as The Robertson Opus (999-year leasehold at Robertson Quay), or explore broader prime district choices on the New Launches Condo District 9 Directory.
