61 of the 269 remaining units are 2 bed premium, at 764 sq ft from $2,044,000. That is the stock this project is really selling right now, whatever the brochure leads with.

Note that 4 types here still show every unit unsold, which usually means a layout released late or one the market has not taken to. Either is worth asking about.


By layout

The Collective at One Sophia price list by layout, as at 6 September 2026

Every layout the developer filed for The Collective at One Sophia, with the units built, the units still unsold and the price band against each. This is the closest thing to a published The Collective at One Sophia price list that exists, and it is the developer's own figure rather than a portal's estimate.

The range across layouts runs $1,431,000 to $3,664,000 — a factor of 2.6. At that spread the layout you choose decides the budget, and the floor you choose only adjusts it.

Where a band shows a single figure, one unit of that layout is left and that is its price. Where it is wide, the difference is floor level and facing rather than the layout.

The site

The Collective at One Sophia site plan: where the blocks sit and what faces what

The site plan fixes what each stack faces, how far apart the blocks sit, and which units back onto the driveway, the substation or the bin centre. None of that changes after handover; the finishes can.

The blocks are addressed 1A & 1B Sophia Road, filed as mixed & private condo. Find the stack you are being shown on the plan before you visit, then ask what sits on the other side of the boundary — the drawing stops at the fence line, and what matters is often just past it.

The unsold units run from $1,250,000 to $3,664,000, at $2,591 to $2,986 psf. Read that as the range of what is left rather than what the project launched at.

For a wider view, the new launch price list carries the same figures for every project still selling in Singapore.


My read

The honest read on The Collective at One Sophia

The stock is not spread evenly. 2H1 (2 bed premium) accounts for 61 of the 231 unsold units at $2,290,000, which makes it the layout The Collective at One Sophia is really selling right now.

The lease started in 2023 and the project is due to complete in Dec 2029. That is 6 years of a 99-year lease gone before anyone moves in, leaving roughly 93 years from handover. Worth checking against anything else you are comparing on the same tenure — the label is identical, the clock is not.

269 of 367 units are still unsold, so The Collective at One Sophia is only 26.7% sold. Early in a launch you get the widest choice of stack, floor and facing, and you are also the one setting the benchmark rather than reading it. Ask what has actually transacted rather than what the price list says.

Against its own district it is unremarkable on price, which is not a criticism. Entry psf of $2,591 against a D9 median of $2,895 means the market has priced it in line with its neighbours, so your decision comes down to the specific unit rather than the project-level number.

Completion is 2029, which is a long wait. That suits an investor with somewhere to live and a buyer who wants today's price for a home they need later. It does not suit anyone who needs keys soon, and progressive payments mean you carry the loan through the build.

With 269 units unsold you have genuine choice, which is rarer than it sounds. Most of what is still selling in the Core Central Region is down to double digits. Use the choice: compare stacks and floors rather than taking the first unit that fits the budget.

It suits you if

you want first choice of stack and facing, you can wait for completion, and you are comfortable being early rather than following the crowd.

Skip it if

the D9 location does not work for you. No amount of pricing fixes a commute you will resent, and there are 5 other projects selling in this district alone.


Gallery

What The Collective at One Sophia is meant to look like

All 5 of these are artist's impressions released by the developer, not photographs. They show the project as drawn rather than as built.

Completion is still years out, which means everything here is a drawing of a decision, not a record of one. Specifications can change before handover. Read the renders for layout and orientation, and take the finishes as a statement of intent.

The developer released some of these without a description, and I have left those uncaptioned rather than invent one.

Common questions

The Collective at One Sophia questions, answered plainly

As at 6 September 2026 the unsold units run from $1,250,000 to $3,664,000, at $2,591 to $2,986 psf. That is the range of what is still available, not the range the project launched at — once the cheapest units go, the bottom of the range rises without the developer changing a price.

No. 269 units are still unsold as at 6 September 2026.

It is 99-year leasehold. Of the 6 new launches still selling in D9, 2 are freehold or 999-year.

Expected 2029. You buy off a plan and wait, with progressive payments through the build.

District 9, which covers Orchard / River Valley, in the Core Central Region.

Its entry psf is in line with the rest of D9, so the project-level number will not decide it for you. With 269 of 367 unsold you still have a real choice of unit. The honest answer depends on which unit, and I would rather look at the actual stack with you than answer it in the abstract.
