House & Family History: The core of the current house may be a house dating from between 1635 and 1641. Hatley was rebuilt by Sir Robert Cotton circa 1700, with two three-bay recessed ranges added in the mid-18th century. The additions and refittings in the neo-Georgian style date from circa 1900. Hatley Park was illustrated by Johannes Kip ("Britannia Illustrata") in 1707.
Garden & Outbuildings: The Park was probably created in the mid-19th century.
