The BAANLYY Building Score, explained.

A transparent 0-100 rating for one specific condo building or tower -- built from seven weighted factors, never for sale, never estimated where we can't credibly assess it. Here's exactly what goes into it, how to read it, and a worked example.

Why this exists

Two condos on the same street can differ enormously -- one three minutes from the BTS with a proven developer and a well-run juristic office, the other ten minutes away with deferred maintenance and an unresponsive management company. The BAANLYY Building Score turns that building-specific difference into one honest, comparable number, distinct from our neighbourhood-level Area Score. It cannot be paid for, and we never publish a score we can't credibly support.

The methodology

What goes into the score

The Building Score is a weighted blend of seven factors, each scored on its own scale and combined into a single 0-100 rating. Location carries the most weight because it's the one thing that can never be renovated -- but condition, developer track record and management decide whether a well-located building is actually a good one to live in.

Location & micro-access25%
Walking distance to the nearest BTS, MRT or Airport Rail Link station, road access, and proximity to hospitals, schools, malls and grocery stores. This looks at the building's exact position, not just its neighbourhood -- two towers on the same soi can score differently if one is a 3-minute walk from the station and the other is 15.
Developer track record15%
How established and reputable the developer is: number of completed projects, on-time delivery history, and how prior projects have held up over time. A first-time developer with no delivered projects scores lower than one with a long, clean completion record.
Building age & condition15%
Age of the building, visible facade and common-area condition, and renovation or refurbishment history. Newer builds and well-maintained older buildings both score well; deferred maintenance and visible deterioration score poorly.
Amenities & facilities15%
Pool, gym, coworking space, function rooms, security staffing and access control, parking ratio, and EV charging. Weighted toward amenities that are actually maintained and usable, not just present on a brochure.
Management & maintenance10%
The reputation and responsiveness of the juristic person (building management), health of common-fee collection, and day-to-day upkeep of shared spaces, lifts and utilities.
Foreign-ownership quota headroom10%
How much of the building's legally capped 49% foreign-freehold quota remains available. A building already near its cap is a real practical constraint for foreign buyers, regardless of how good the building otherwise is.
Value versus comparables10%
Asking or recent price per square metre compared with verified comparable buildings in the same immediate area, drawing on BAANLYY's own price-per-sqm research. A building priced well above comparable stock scores lower here even if every other factor is strong.
Reading the number

Score bands

0-39 · EmergingA newer or less-established building, an unproven developer, or a property with real gaps in one or more factors -- not necessarily a bad choice, but one that needs closer individual due diligence.
40-59 · StandardA solid, unremarkable building: reasonable location, adequate amenities and a workable management setup, without standout strengths.
60-79 · StrongA well-located, well-maintained building from a credible developer with healthy amenities and management -- a dependable choice for most renters and buyers.
80-100 · BAANLYY SelectTop-tier across nearly every factor: excellent micro-access, a proven developer, strong condition, real amenities, solid management and fair pricing relative to comparables.

How the maths actually works

This is a hypothetical, illustrative building -- not a real, named property -- built to show exactly how the seven factors combine into a final score. A well-located, mid-market tower with a solid but not flawless profile might score like this:

FactorWeightPoints earned
Location & micro-access25 pts max22
Developer track record15 pts max12
Building age & condition15 pts max11
Amenities & facilities15 pts max13
Management & maintenance10 pts max8
Foreign-ownership quota headroom10 pts max6
Value versus comparables10 pts max7
Total Building Score100 pts max79 · Strong

In this illustration, the building loses the most ground on foreign-ownership quota headroom (already well-subscribed) and value versus comparables (priced a little above nearby stock) -- exactly the kind of factor-level detail that matters more than the single headline number. Always read the breakdown, not just the total.

Frequently asked
What is the BAANLYY Building Score?A transparent 0-100 rating for a specific condo building or tower, built from seven weighted factors: location micro-access, developer track record, building age and condition, amenities, management quality, foreign-ownership quota headroom, and value versus comparable buildings nearby. It rates the building itself, distinct from the BAANLYY Area Score, which rates the surrounding neighbourhood.
How is this different from the BAANLYY Area Score?The Area Score rates a whole neighbourhood on factors like transit access, safety, walkability, nightlife and family-friendliness. The Building Score zooms in on one specific tower -- its exact distance to the nearest station, its developer's track record, its physical condition, and its own amenities and management. A great area can contain both strong and weak buildings; use both scores together for the full picture.
Can a developer or agent pay to raise a Building Score?No. BAANLYY never sells placement or accepts payment to influence a score. Every factor is assessed the same way for every building, and we do not publish a Building Score for a property without genuinely assessing each factor -- we would rather leave a factor unscored than estimate it without a credible basis.
Where do the inputs come from?Location and transit distance draw on BAANLYY's own transit and mapping data. Developer track record draws on public project-completion history. Value versus comparables draws on BAANLYY's price-per-sqm research for the same area. Amenities, condition and management are assessed from direct building information and, where available, resident and buyer feedback. We do not fabricate a score for any factor we can't credibly support -- see the worked example below for how a real assessment is built up factor by factor.
Is a low Building Score a reason to avoid a building?Not automatically -- treat it as a prompt to look closer, not a verdict. A newer building from a first-time developer might score lower on track record simply for lack of history, even if construction quality is genuinely excellent. Read the factor breakdown, not just the headline number, before deciding.
Does the Building Score account for price?Partly, through the value-versus-comparables factor, which checks price per square metre against verified nearby comparables. It does not tell you whether a building fits your personal budget -- pair it with our price-per-sqm report and your own numbers before making a decision.

The BAANLYY Building Score is an informational, editorial signal built from BAANLYY's own proprietary methodology -- not a professional valuation, structural survey, legal opinion or investment recommendation. Scores are only published where we can credibly assess each factor; we do not estimate or fabricate a rating for a building we haven't genuinely reviewed. Building condition, management quality, developer standing, foreign-quota availability and comparable pricing all change over time -- verify current details with a licensed agent, surveyor or lawyer before making a decision. BAANLYY never accepts payment to raise a Building Score.
