"Boutique" and "luxury" are two of the most common words used to market small condo developments in Singapore. But BCA's own construction quality data tells a more complicated story about how well many of these projects are actually built.
Small condos, typically fewer than 50 units, are statistically more likely to score poorly on BCA's construction quality assessment (Conquas) than larger developments — regardless of how they're marketed.
Small condo developments are often marketed with the most premium language in the business — "boutique," "exclusive," "luxury living." But data from the Building and Construction Authority (BCA), reported by The Straits Times, shows small private residential projects are disproportionately more likely to score poorly on construction workmanship than their larger counterparts.
Conquas — the Construction Quality Assessment System, mandatory since 1989 for government land sales projects — evaluates workmanship and major defects including water seepage, cracked or chipped tiles, broken windowpanes and shower screens, and missing or broken door hardware. Over the past 6 years, BCA assessed 167 projects. Small condos, typically under 50 units, accounted for more than 58% of the projects that scored in the three lowest bands.
| Band Range | Total Projects | Small Condos Among Them |
|---|---|---|
| Band 4–6 (lowest, poorest) | 48 | 28 (58%) |
| Band 1–3 (relatively well-built) | 119 | 17 (14%) |
The pattern is stark: small condos were nearly four times as likely, proportionally, to appear among the poorly-rated group as among the well-rated one. And several of the weaker performers were marketed explicitly as premium developments — including one Mountbatten Road project describing itself as offering "luxurious semi-detached homes" with a marble facade, which received a Band 5 rating, and a 21-unit District 9 boutique condo marketed for its "luxury," also rated Band 5.
The core reason, per NUS Business School's provost's chair professor of real estate: small projects tend to rely far more heavily on on-site construction methods, while larger developments can justify investing in prefabricated and precast systems — components like entire bathrooms and toilets fabricated in a factory under controlled conditions, then transported and hoisted into place. On-site work, by contrast, is exposed to weather, requires setting formwork and pouring concrete on location, and is more vulnerable to inconsistent execution.
This doesn't mean every small condo is poorly built, or that every large development is flawless — some developers had a genuine mix of results across their own portfolio. One developer with 11 rated projects, for instance, saw 6 score poorly while 5 others, including two rated Band 1, performed well. The pattern is statistical, not absolute — but it's a real enough pattern that it's worth checking before you commit to a specific project.
From 22 May 2026, a new Land Sales Disqualification Framework gives BCA a sharper tool: developers with severe regulatory non-compliances affecting safety, or a pattern of consecutive projects with major defects, can now be disqualified from bidding on residential land sales sites for up to 5 years. This sits on top of the existing Conquas requirement — developers with at least one project rated Band 4, 5 or 6, or with significant major defects in the past 3 years, must now undergo Conquas assessment on their residential projects going forward, even if they weren't previously required to.
The numbers on defect rates make the stakes clear: fewer than 1 in 1,000 units built by a Band 1 developer had major defects reported after Temporary Occupation Permit (TOP). For a Band 6 developer, that figure jumps to 80 per 1,000 units — a meaningful difference in the odds of moving into a home with real defects to fix.
A Conquas band rating isn't something most buyers think to ask about — marketing brochures certainly won't volunteer it. But it's public information, and for a small boutique development especially, it's worth checking before you commit, not after you've collected the keys.
One important nuance: a poor Conquas score doesn't automatically mean walk away — some developers' scores reflect one difficult project rather than a systemic issue, and the developer's own explanation and remediation matter too. What it does mean is that "small and premium-marketed" is not the same thing as "well-built," and it's a question worth asking directly, not assuming.
