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 Hemel Hempstead, Great Gaddesden, homes with the same number of habitable rooms vary enormously in size.
| Habitable rooms | Smaller (10th) | Typical | Larger (90th) | Sales |
|---|---|---|---|---|
| 1 | 20 m² | 27 m² | 32 m² | 19 |
| 2 | 33 m² | 43 m² | 50 m² | 328 |
| 3 | 53 m² | 59 m² | 75 m² | 473 |
| 4 | 62 m² | 78 m² | 97 m² | 970 |
| 5 | 71 m² | 87 m² | 110 m² | 835 |
| 6 | 97 m² | 116 m² | 152 m² | 362 |
| 7 | 110 m² | 137 m² | 207 m² | 285 |
| 8 | 126 m² | 156 m² | 209 m² | 129 |
| 9 | 150 m² | 184 m² | 230 m² | 59 |
| 10 | 205 m² | 225 m² | 283 m² | 10 |
The widest spread here is among homes with 7 habitable rooms, ranging from 110 to 207 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.
