A Carpenter Oak house is featured in the 2nd series of Grand Designs. The home’s unique cross-shaped layout centres around an octagonal kitchen - a stunning open-plan space perfect for socialising.

A full-scale trebuchet for Warwick Castle is built - it is the world’s largest working trebuchet based on designs from the 13th and 14th centuries.
