A solid walnut floor laid in 2006 and sourced from the Natural Wood Floor Company in Wandsworth. Boards are not glued together, they were glued to the tiled floor. Max length around 6ft/2m, width 5" (not including the tongue) and thickness 20mm.
The original floor was just under 50sqm so there is probably around 40-5 sqm of good quality wood. Located in Fulham.
