The space signal
Property listings describe homes by bedroom count, but that is not recorded in any public dataset. What is recorded is the number of habitable rooms — bedrooms and reception rooms together — and the total floor area. In Chelsea, homes with the same number of habitable rooms vary enormously in size.
| Habitable rooms | Smaller (10th) | Typical | Larger (90th) | Sales |
|---|---|---|---|---|
| 1 | 18 m² | 28 m² | 36 m² | 384 |
| 2 | 32 m² | 46 m² | 69 m² | 1,040 |
| 3 | 55 m² | 74 m² | 105 m² | 1,231 |
| 4 | 77 m² | 101 m² | 150 m² | 579 |
| 5 | 102 m² | 138 m² | 167 m² | 274 |
| 6 | 129 m² | 174 m² | 228 m² | 304 |
| 7 | 151 m² | 205 m² | 266 m² | 240 |
| 8 | 179 m² | 234 m² | 318 m² | 197 |
| 9 | 223 m² | 292 m² | 419 m² | 157 |
| 10 | 213 m² | 280 m² | 391 m² | 74 |
| 11 | 233 m² | 361 m² | 508 m² | 41 |
| 12 | 392 m² | 405 m² | 537 m² | 22 |
The widest spread here is among homes with 11 habitable rooms, ranging from 233 to 508 m². Two properties advertised the same way can differ by more than half their floor area, which is why price per square metre is a more useful comparison than price alone.
