Herringbone parquet floors are installed one piece at a time in a few different variations, either parallel or diagonally to the wall. Traditionally, herringbone is laid with the points running in the longest direction of a room or directed at a focal point. To create the illusion of a larger space, herringbone can be installed on the diagonal.
Herringbone should be glued down for best results. The pieces have grooves on three sides and a tongue on the long side. Precise machining is critical, particularly with herringbone more than any other pattern.
