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 Southborough, Rusthall, homes with the same number of habitable rooms vary enormously in size.
| Habitable rooms | Smaller (10th) | Typical | Larger (90th) | Sales |
|---|---|---|---|---|
| 1 | 21 m² | 34 m² | 50 m² | 26 |
| 2 | 34 m² | 43 m² | 58 m² | 523 |
| 3 | 49 m² | 68 m² | 92 m² | 665 |
| 4 | 55 m² | 73 m² | 91 m² | 760 |
| 5 | 73 m² | 89 m² | 113 m² | 884 |
| 6 | 93 m² | 119 m² | 148 m² | 497 |
| 7 | 120 m² | 161 m² | 216 m² | 336 |
| 8 | 147 m² | 181 m² | 242 m² | 253 |
| 9 | 178 m² | 216 m² | 270 m² | 148 |
| 10 | 173 m² | 262 m² | 338 m² | 91 |
| 11 | 238 m² | 316 m² | 451 m² | 43 |
| 12 | 275 m² | 371 m² | 494 m² | 22 |
The widest spread here is among homes with 1 habitable rooms, ranging from 21 to 50 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.
