Parquet
flooring was popular between the Edwardian and Thirties period. Parquet
flooring is most suitable for solid floors i.e. concrete, which would
most likely to be on the ground floor of the house like the hall and
living space. Parquetry is small blocks of hardwood glued down onto
a subfloor providing a hardwearing surface to cater with daily life.
The block would be laid down in a geometrical pattern to create a decorative
effect; the herringbone pattern was most popular.
