Solid Red Oak, Buckinghamshire
Hedsor House, Taplow
This stately home is a popular venue for weddings, conferences and film shoots. The floor consisted of solid Red Oak boards (most likely either American or Canadian) nailed directly to the joists beneath. The floor had been re-finished most recently with lacquer, some thirty to forty years previously.
As you can see from the top left corner of the photo below with the vacuum cleaner in it, the lacquer had turned to a rather dirty brown colour.
