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 Blackmore End, Colney Heath, homes with the same number of habitable rooms vary enormously in size.
| Habitable rooms | Smaller (10th) | Typical | Larger (90th) | Sales |
|---|---|---|---|---|
| 1 | 28 m² | 29 m² | 30 m² | 32 |
| 2 | 37 m² | 43 m² | 52 m² | 426 |
| 3 | 53 m² | 61 m² | 71 m² | 575 |
| 4 | 60 m² | 76 m² | 92 m² | 509 |
| 5 | 76 m² | 96 m² | 118 m² | 770 |
| 6 | 97 m² | 119 m² | 146 m² | 506 |
| 7 | 109 m² | 135 m² | 184 m² | 456 |
| 8 | 129 m² | 159 m² | 211 m² | 302 |
| 9 | 150 m² | 190 m² | 255 m² | 113 |
| 10 | 169 m² | 216 m² | 339 m² | 53 |
| 11 | 215 m² | 278 m² | 437 m² | 20 |
| 12 | 261 m² | 373 m² | 373 m² | 5 |
The widest spread here is among homes with 11 habitable rooms, ranging from 215 to 437 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.
