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 Ashendon, Brill, homes with the same number of habitable rooms vary enormously in size.
| Habitable rooms | Smaller (10th) | Typical | Larger (90th) | Sales |
|---|---|---|---|---|
| 2 | 42 m² | 47 m² | 56 m² | 53 |
| 3 | 53 m² | 64 m² | 76 m² | 94 |
| 4 | 65 m² | 80 m² | 101 m² | 249 |
| 5 | 76 m² | 92 m² | 122 m² | 272 |
| 6 | 100 m² | 131 m² | 182 m² | 248 |
| 7 | 122 m² | 156 m² | 200 m² | 258 |
| 8 | 140 m² | 174 m² | 227 m² | 214 |
| 9 | 156 m² | 210 m² | 274 m² | 126 |
| 10 | 190 m² | 236 m² | 408 m² | 55 |
| 11 | 241 m² | 309 m² | 423 m² | 16 |
| 12 | 228 m² | 323 m² | 386 m² | 7 |
The widest spread here is among homes with 10 habitable rooms, ranging from 190 to 408 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.
