These are Victorian woodworks. The old oak block floor was very
shabby, parts of it were missing entirely and it hardly did justice
to the grand entrance hall of the sustantial manor house it served.
We made good the missing blocks, refitted many that were loose,
then filled the open joints and sanded and refinished the floor.
If you click on this picture it takes you to a detail of the floor
instead of just a larger version of this picture.
