| The following ranges of probable dates of construction refer only to Surrey. |
|---|
| Open hall (up to 1540) |
| Characteristically a 4 bay house with 2 central bays open to the roof, and central hearth. |
| Half-floored hall (1500 - 1540) |
| Open hall house with upper storey of one central bay floored. |
| Smoke bay house (1530 -1620) |
| A short bay (central or end) sealed off from the upper part of the house as an escape for smoke. |
| Smoke hood house (1530 -1620) |
A timber-framed enclosure supported on the mantle beam of the hearth and tapering to
an outlet on the roof - intermediary between Smoke bay and Chimney. |
NOTE: The fundamental difference between a smoke bay and a smoke hood is that
the hood is inserted into a bay and is not a bay itself. |
| Chimney house (1550 onwards) |
| Brick built flue, central or end. |
