How Blk 205 Boon Lay DR scores 70.8/100

Every number on this block’s page, opened up. Below is each pillar, each component inside it, the exact walk time or distance we measured, and the weighted arithmetic that rolls it up — so you can check the score yourself. Nothing here is hand-tuned; the same weights apply to all ~12,800 blocks.

71Overall / 100
How to read this

A closer amenity scores higher on a straight-line decay: full marks at or under the “full” threshold, zero at or beyond “zero”, and a straight line between. Remaining lease uses the mirror growth curve. A component with nothing in range scores 0 — never a fabricated amenity. See the full methodology for the formulas and data sources.

Each pillar, component by component

Sub-scores are frozen in the current snapshot (2026-11); the measured input beside each is the amenity that produced it.

Transport

Pillar57.9

Everyday mobility. The nearest MRT/LRT exit dominates because it sets your reach across the island; the nearest bus stop covers the last mile; a small slice credits a planned-but-unopened station nearby.

Who-it-suits scores

Each persona score re-weights the same pillars for a different household. The base is a weighted average of the pillar scores above; four personas then get a small, bounded nudge (≤ ±3) if the planning area’s census mix fits them.

PersonaPillar-weighted baseDemographic fitFinal
Young Families74.7+0.675.3
Seniors69.0-1.267.8
Renters68.0-0.567.5
EV Owners73.8-0.673.2
Investors

0.55 × overall (70.8) + 0.25 × resale momentum (28) + 0.20 × value (18) = 49.4 ✓ matches 49.4

Momentum is the subzone’s resale price-per-sq-ft trend as a 0–100 percentile against all subzones.
