One Chuan Grove Floor Plans: Reading the Tentative Unit Mix

The English ERA project highlights of 3 November 2026 give One Chuan Grove's first unit schedule: 1,056 homes from 1-bedroom to 5-bedroom, at about 474 to 1,561 sq ft. The schedule is tentative and subject to authorities' approval, so sizes and counts could still change. The floor plan drawings themselves are expected around the preview, which opens on 13 February 2027.

Even without drawings, the numbers say a lot. Weighting each type by its count, the average home is about 891 sq ft, by our arithmetic, close to a compact three-bedder. More than half of the homes have three bedrooms or more, and one-bedders are almost absent. This page summarises the mix, reads it by buyer type, and sets out the metrics we suggest you use once the plans are released.

5-bedroom luxury with private lift273%1,561 sq ft1,561 sq ft

Two patterns are worth noting. Within the two-bedroom group, most units are the larger premium and premium-plus-study layouts rather than the 581 sq ft entry type, which is why the group average sits nearer 670 sq ft than 600. And 108 homes, about 10% of the total, are luxury layouts served by a private lift: 81 four-bedders at 1,356 sq ft and 27 five-bedders at 1,561 sq ft. The full unit-by-unit schedule will be confirmed with the floor plans.

What the mix means for each buyer type

  • Singles and couples buying their first private home. With only 3 one-bedders, the realistic entry point is the 581 sq ft two-bedder. The plain two-bedroom is one of the less common two-bedroom variants on the schedule, so if lowest quantum is your aim, expect competition for those stacks.
  • Couples planning for a child or a home office. The two-bedroom plus study at 710 sq ft is the largest single sub-group of two-bedders. A study adds flexibility without the jump in quantum to a three-bedder, which starts at 807 sq ft.
  • Young families. The three-bedroom range of 807 to 1,001 sq ft covers 315 homes. The flexi variants at 1,001 sq ft add a space that can serve as a helper's room, study or play area.
  • Growing or multi-generation families. At 240 homes, four-bedders are a much larger slice than at many suburban launches. They range from 1,076 sq ft to 1,356 sq ft, the largest with a private lift.
  • Buyers wanting the largest homes. The 27 five-bedroom luxury units at 1,561 sq ft are the top of the range and, at about 3% of the total, the scarcest family type.

By our arithmetic, space per bedroom is tightest in the entry three- and four-bedders, at roughly 269 sq ft per bedroom, and most generous in the five-bedder, at about 312 sq ft. That ratio is crude, but it flags which layouts will need the closest look at room dimensions.

Metrics for comparing layouts

MetricHow to calculateWhy it matters
Usable ratioInternal living area ÷ total strata areaShows how much you pay for space you actually use
Bedroom-to-size ratioTotal area ÷ number of bedroomsHighlights layouts with very small rooms
QuantumSize × psfWhat you actually pay
Wet area shareBathrooms and yard ÷ total areaHigh shares reduce living space
FrontageWidth of living area facing outAffects light and the feel of space

Strata area usually includes balconies, air-conditioner ledges and similar spaces. Two units of the same size can feel very different depending on how much of the total is usable living space.

Questions to ask about each unit type

  • Is the kitchen enclosed or open, and can it be closed off for heavy cooking?
  • Are bedrooms large enough for the furniture you own?
  • Is there a dedicated study or flexible space?
  • Do bathrooms have windows for ventilation?
  • How does the layout relate to the unit's facing on the site plan?

It is also worth checking whether the same unit type appears in more than one variant. Large projects often offer a standard layout and a variation, for example with or without a study or with a different balcony arrangement, at slightly different sizes. Small differences in size can translate into meaningful differences in quantum.

When pricing is released, compare not only psf but also quantum. A smaller, efficient layout at a higher psf can be cheaper in total than a larger, less efficient one. The price list page explains how pricing is typically structured across stacks and floors.

With five bedroom types and several variants within each, the most useful first step is to decide which one or two types fit your household and budget, then compare variants within those types. The price list page converts the tentative sizes into illustrative quantums at the analysts' estimate.
