A District 9 landmark gets rebuilt — as a transit-core compact play.
Peace Centre and Peace Mansion sat on Sophia Road for half a century, a tired commercial-and-residential block that tried to go en-bloc repeatedly over more than a decade before it finally sold. The S$650 million deal — accepted on 3 December 2021, after a 2019 attempt at a S$688 million reserve had collapsed — closed one of Singapore's longest collective-sale sagas. What replaces it keeps the old DNA: homes stacked over offices over retail, rebuilt as One Sophia.
The residential half — The Collective at One Sophia — is 367 units, studio to three-bedroom, sitting above a 13-storey strata office tower and a two-storey retail podium. It previewed quietly: the two-day preview from 6 November 2024 moved 35 units at an average of roughly S$2,750 psf, rising to 68 units (about 18%) by the preview's close on 30 November 2024, before the gallery closed and public sales opened in January 2025. For the Core Central Region in late 2024 — where new sales had been muted since the April 2023 cooling round — that was a respectable opening.
What you're actually buying here is connectivity, not space. The site is wrapped by MRT: Bencoolen (Downtown Line) about 310 m away, the three-line Dhoby Ghaut interchange about 420 m, Rochor about 490 m — all inside a flat five-minute walk. The School of the Arts is effectively next door. This is a city-core, lock-up-and-go address for the professional and the local investor, not a family-and-catchment buy.
The pricing reflects the post-2023 reality. With ABSD on foreigners at 60%, the development was set at a level — around S$2,750 psf average — aimed squarely at Singaporeans and PRs. The consortium behind it is CEL Development (Chip Eng Seng), Sing-Haiyi Crystal (SingHaiyi) and Ultra Infinity, the entity carrying the KSH-linked stakes.
Previewed at ~S$2,750 psf average.
The Collective at One Sophia opened with a two-day preview from 6 November 2024, moving 35 units at an average of about S$2,750 psf, rising to 68 of 367 units (~18%) by the preview's close on 30 November 2024, with public sales following in January 2025. The cleanest comp is its same-enclave neighbour Sophia Hills; the freehold D9 names sit well above:
- Studios from S$1.141M (~S$2,650 psf); 3-bedders from ~S$2.85M (~S$2,782 psf)
- Sophia Hills (99-yr, 2018), same street: resale ~S$2,112 psf on the last 12 months
- 8 Saint Thomas (freehold, River Valley): ~S$3,000 psf · Klimt Cairnhill (freehold, prime): ~S$3,373 psf
Priced for locals — by ABSD design. The 60% foreigner rate since April 2023 pushed the project to price for Singaporeans and PRs.
| Project | District | Units | Tenure | Completion | PSF |

The Collective figure is the developer's ~S$2,750 psf preview average (Nov 2024). Comparable PSFs are caveat-derived resale/transaction averages over the trailing 12 months (Sophia Hills and 8 Saint Thomas via 99.co; Klimt Cairnhill via EdgeProp), each cross-checked from its own source. Tenure and completion differ across the set — read PSF in that light, not as a like-for-like.
Compact-led, two-bedders the core.
The developer's unit schedule splits the 367 homes into 68 studios, 107 one-bedroom units, 158 two-bedroom units, and 34 three-bedroom units. Two-bedders are the single largest band at ~43%; studios and one-bedders together make up nearly half the project — a compact, investor-friendly mix that fits the transit-core, local-tenant thesis.
| Type | Total units | Size (sqft) | Pricing |
|---|---|---|---|
| Studio | 68 | 431 – 452 | from S$1.141M (~S$2,650 psf) |
| 1-bedroom (Suite / Premium / +Study) | 107 | 484 – 549 | from ~S$1.35M (developer-listed) |
| 2-bedroom (Deluxe / Premium / +Study) | 158 | 646 – 764 | city-fringe pricing — funnels to #brochure |
| 3-bedroom (Premium / Luxury) | 34 | 1,023 – 1,249 | from ~S$2.85M (~S$2,782 psf) |

1 Sophia Road — the Mount Sophia edge of District 9.
The Collective at One Sophia sits where Sophia Road meets the Dhoby Ghaut / Mount Sophia node — a pocket that straddles the Orchard shopping belt, the Bras Basah arts district and the Bencoolen civic stretch. Plaza Singapura, The Cathay and Fort Canning Park are all within a short walk.
Connectivity is the headline. By OneMap straight-line distance, Bencoolen MRT (DT21) is about 310 m, the three-line Dhoby Ghaut interchange (NS24/NE6/CC1) about 420 m, and Rochor (DT13) about 490 m — all inside a flat five-minute walk. Few District 9 sites put three lines this close.
What's genuinely next door: the School of the Arts (~280 m), the Fort Canning green spine, and the Orchard/Dhoby Ghaut retail core. This is a walk-everywhere city-core address — the trade-off being compact homes rather than space and a deep school catchment.

Trains, malls, arts, green — all on foot.
The defining feature of this address is density of access: three MRT lines, the Orchard/Dhoby Ghaut shopping belt, the Bras Basah arts cluster and Fort Canning's green spine, all within a walk. What it isn't is a quiet, leafy enclave — this is the busy city core, and you buy it for exactly that.

Two thesis-driven buyers — and one segment we'd steer away.
Most launch pages try to be everything to every buyer. We don't think The Collective at One Sophia is that. Here's where it genuinely shines, and where it doesn't.
Transit-core, local-tenant compact.
Three MRT lines within a five-minute walk, a compact unit mix (studios and one-bedders are nearly half the project), and a city-core address aimed at the local professional tenant — this is a rental-yield play built for the post-ABSD market.
The cleanest yield read is to pull URA rental contracts for same-street Sophia Hills and the Mount Sophia cluster and model from real transactions — we won't quote a yield figure we can't two-source. The structural draw is connectivity, and it's genuine.
City professionals who want to walk everywhere.
If you work in the CBD or Orchard and want to live without a car — three lines on the doorstep, Plaza Singapura and the arts district on foot, brand-new and integrated with retail below — this is about as connected as District 9 gets.
The honest version: these are compact homes. The largest three-bedders top out at 1,249 sqft, and there is no large-format family stock. If you need space and a mainstream-primary catchment, this isn't the address — the draw is location, not size.
Freehold seekers and space-first families.
If freehold tenure is non-negotiable, the 99-year lease here is the wrong fit — the freehold District 9 names (8 Saint Thomas, Klimt Cairnhill) are the alternative, at a meaningfully higher PSF. And if you need four bedrooms, a deep mainstream-school catchment, or a quiet residential enclave, this busy, compact city-core block will frustrate you. It is a connectivity buy, full stop.
What the brochure won't tell you.
Three dates, not one — mind the gap.The developer's expected TOP is around 2028, but vacant possession is dated 31 December 2029 and legal completion 31 December 2032. The 2032 figure is the legal long-stop, not the build target; portals that quote "TOP Dec 2029" are citing vacant possession. Plan around ~2028 completion and verify against your S&P.
This is leasehold, on a freehold street.Same-enclave Sophia Hills is also 99-year, but the prime D9 names buyers compare against — 8 Saint Thomas, Klimt Cairnhill — are freehold. You're paying new-build, integrated-development pricing for a leasehold tenure. That's the trade.
Compact, by design.Studios and one-bedders are nearly half the 367 units, and the largest three-bedder is 1,249 sqft. Great for the single professional or investor; thin for a family that wants room. Don't expect large-format layouts here.
You're buying into a building site of a precinct.The wider One Sophia mixes 122 offices and 127 shops below the homes, and the Mount Sophia / Dhoby Ghaut node is busy, urban and not quiet. For some buyers that energy is the appeal; for others it's the deal-breaker. Visit at different times of day before committing.
Mixed-use means shared common areas.Residents share the basement carpark and the ground-plane with office workers and retail traffic. Integrated developments trade convenience for a degree of privacy and quiet you'd get in a pure-residential block. Read the strata and management arrangements carefully.
A slow, selective market backdrop. CCR new-sale demand has been muted since the April 2023 cooling round, and the preview moved about 18% (68 of 367 units by its 30 Nov 2024 close) — encouraging for the segment, but not a sell-out. Take-up has since drifted up to roughly 27% by mid-2026 — see the live availability panel above for the exact current balance; treat the absorption pace as steady rather than frantic, and negotiate accordingly.

What buyers keep asking.
- When is The Collective at One Sophia expected to TOP? +
- The Collective at One Sophia carries three different dates, which is where confusion creeps in. The developer's expected TOP is around 2028; the expected date of vacant possession is 31 December 2029 (this is the date many listing portals quote as 'TOP Dec 2029'); and the expected date of legal completion is 31 December 2032. The 2032 figure is the legal long-stop, not the build target — as of June 2026, treat ~2028 as the realistic completion year and 2029 as vacant possession.
- Who is the developer of The Collective at One Sophia? +
- The Collective at One Sophia sits on the former Peace Centre / Peace Mansion site, bought in a S$650 million collective sale accepted on 3 December 2021. The buying joint venture is three entities: CEL Development (a wholly-owned Chip Eng Seng subsidiary, 40%), Sing-Haiyi Crystal (a SingHaiyi / Haiyi Properties JV, 30%), and Ultra Infinity (30%). Ultra Infinity is the entity that carries the KSH Holdings, SLB Development and Ho Lee Group stakes — which is why some marketing material lists all five names. At preview, SingHaiyi and Ultra Infinity were the parties marketing the homes.
- How many units does The Collective at One Sophia have, and what's the unit mix? +
- The Collective at One Sophia has 367 residential units — the residential component of the larger One Sophia mixed-use development. The developer's unit schedule breaks the mix into 68 studios (431–452 sqft), 107 one-bedroom units (484–549 sqft), 158 two-bedroom units (646–764 sqft), and 34 three-bedroom units (1,023–1,249 sqft). Two-bedders are the single largest band at ~43% of the project. Don't confuse the residential count with the commercial One Sophia, which adds 122 strata offices and 127 retail shops on the podium below.
- What was the average price at The Collective at One Sophia? +
- The Collective at One Sophia sold 35 units on opening — the two-day preview from 6 November 2024 — at an average of about S$2,750 psf, rising to 68 units (18% of the 367) by the preview's close on 30 November 2024. Studios were the entry point, from S$1.141 million (~S$2,650 psf); three-bedders started from about S$2.85 million (~S$2,782 psf). Public sales began in January 2025. As of June 2026, the live balance is shown in the availability panel above and refreshes nightly.
- Is the preview really 'two-day' or 'five-day'? +
- The Collective at One Sophia's preview is the kind of small discrepancy worth naming. EdgeProp's own headline called it a 'five-day preview', but the body of the same report describes a two-day preview sale — opening on Wednesday 6 November 2024 — and the wider private preview ran until 30 November 2024 before the sales gallery closed in December ahead of the January 2025 public launch. The defensible read is that 35 units sold over the two-day opening, rising to 68 by the 30 Nov 2024 preview close; the headline's day-count is loose.
- How far is The Collective at One Sophia from an MRT? +
- The Collective at One Sophia is unusually well-connected for a District 9 site. By OneMap straight-line distance, Bencoolen MRT (DT21, Downtown Line) is the closest at about 310 m, Dhoby Ghaut (NS24/NE6/CC1 — a three-line interchange) is about 420 m, and Rochor (DT13) is about 490 m. All three sit inside a 500 m radius, which is rare; the Dhoby Ghaut interchange in particular puts the North-South, North-East and Circle lines within a flat ~5-minute walk.
- What's the catchment school situation at The Collective at One Sophia? +
- The Collective at One Sophia's headline school is the School of the Arts (SOTA), about 280 m away — effectively next door, though SOTA is a specialised arts school with its own admissions, not a catchment primary. The nearest mainstream primary may be St Margaret's Primary (within 1 km); Anglo-Chinese School (Junior) is roughly 1 km away (verify exact distances on OneMap, as published figures vary). This is a city-core address, so it is not a deep mainstream-primary catchment the way the Bukit Timah belt is — the draw here is connectivity and the arts/civic precinct, not P1 priority.
- Is The Collective at One Sophia a good investment? +
- Whether The Collective at One Sophia works as an investment turns on the District 9 rental thesis: a small-format, transit-dense city-core address aimed at professionals and the local upgrader rather than foreign buyers. With ABSD on foreigners at 60% since April 2023, the project was priced — at around S$2,750 psf average — to attract Singaporeans and PRs. We won't quote a yield figure we can't two-source; the cleanest read is to pull URA rental contracts for nearby Sophia Hills and the Mount Sophia cluster and model from real transactions.
- How does The Collective at One Sophia compare to other District 9 condos? +
- The Collective at One Sophia's ~S$2,750 psf preview average sits between its neighbours. Same-enclave Sophia Hills (99-year, 2018) trades at roughly S$2,112 psf on resale; 8 Saint Thomas (freehold, River Valley) is around S$3,000 psf; and prime freehold Klimt Cairnhill is near S$3,373 psf. So this is a new-build, 99-year leasehold entry priced above the older same-street leasehold stock but well under the freehold prime names — which is the trade you're making: brand-new and integrated, but leasehold and city-core compact.
- What is the One Sophia mixed-use structure? +
- The Collective at One Sophia is only the residential half of the story. The wider One Sophia redevelopment stacks 367 homes above a commercial base: a 13-storey strata office tower (122 office units) and a 2-storey retail podium (127 shops), with three basement carpark levels shared between residents and the public. The residential lobbies and facilities sit above the commercial floors. If you see a separate 'One Sophia' listing, that's the office/retail component — a different entry from the homes on this page.
- What did the Peace Centre site sell for, and why does the history matter? +
- The Collective at One Sophia replaces Peace Centre and Peace Mansion, a long-running en-bloc saga that finally closed at S$650 million — an offer made by private treaty and accepted on 3 December 2021, after a 2019 attempt at a S$688 million reserve had failed. The combined site held 232 commercial units, 86 apartments and a 162-lot carpark. The history matters because the mixed-use DNA of the new scheme — homes over offices over retail — directly inherits the old centre's commercial-and-residential footprint.
- Who is The Collective at One Sophia best suited to? +
- The Collective at One Sophia fits the single professional or couple who wants a brand-new, lock-up-and-go city-core home within a flat walk of three MRT lines, and the local investor targeting that same tenant. It fits less well for families needing space and a mainstream-primary catchment, or for buyers who specifically want freehold tenure — the freehold D9 names (8 Saint Thomas, Klimt Cairnhill) are the alternative, at a higher PSF.
- How do I book a showflat appointment? +
- To book a The Collective at One Sophia showflat appointment, drop your details via the form on this page. Our partner agent will follow up with available slots, the latest balance-unit list, indicative pricing by stack, and any developer-side incentives still active.
Why the preview held up.
68 of 367 units booked over the Nov 2024 preview (35 on the two-day opening), in a CCR market that had been muted since April 2023. Here's what those buyers were reading — and what it means for the balance.
68 of 367 units (18%) sold by the 30 Nov 2024 preview close (35 on the two-day opening from 6 Nov 2024) at ~S$2,750 psf · about 27% taken up to date · studios from S$1.141M · ask for the current balance, or see the live panel above.
Get the balance unit list →- 01Three MRT lines inside a five-minute walk.Bencoolen (310 m), the three-line Dhoby Ghaut interchange (420 m) and Rochor (490 m) all sit inside a 500 m radius — OneMap-measured. For a city-core rental play, that connectivity is the whole thesis, and it's structurally irreproducible.
- 02Priced for locals, in a 60%-foreigner-ABSD world.At ~S$2,750 psf average, the project was set to attract Singaporeans and PRs rather than foreign capital. In the post-April-2023 CCR, pricing to the local upgrader is the move that clears units.
- 03Entry from S$1.141M for a studio.A sub-S$1.2M ticket for a brand-new, integrated District 9 home — at ~S$2,650 psf — is a genuinely low absolute entry for the location. That quantum is what moved the studios first.
- 04A landmark site with fifty years of pedigree.The former Peace Centre / Peace Mansion took repeated en-bloc attempts over more than a decade and a S$650 million deal to assemble. Buying the redevelopment of a known Sophia Road landmark — homes over offices over retail — is a different proposition from an anonymous infill plot.
- 05Priced under the freehold D9 names, above the old leasehold stock.At ~S$2,750 psf, The Collective slots between same-street Sophia Hills (~S$2,112 psf resale) and the freehold prime names (8 Saint Thomas ~S$3,000, Klimt Cairnhill ~S$3,373). New-build and integrated, but honestly leasehold — buyers priced that in.
