Brocket Hall is a Grade I-listed classical country house set in a large park at the northern end of the urban area of Hatfield in Hertfordshire, England. The estate is equipped with two golf courses and seven smaller listed buildings, apart from the main house.
The freehold on the estate is held by Baron Brocket. The Club Corporation of Asia (CCA) currently holds the property on a long leasehold which will only expire in the middle of the 21st century.
Sir Matthew Lamb, 1st Baronet, purchased the estate in 1746, complete with Brocket Lea, the older house on the south side of the upper course of the river visible from almost all of the estate. He built the hall as it is seen today around 1760 to the designs of the architect Sir James Paine.
Brocket Hall is a tall red brick neoclassical house in a fine landscape setting with a Palladian bridge. The interior of the house is mostly not on a grand scale but the exceptions are the main staircase and the Grand Saloon that was decorated specifically for entertaining royalty. The walls are lined with silk, the original furniture was made by Chippendale, the ceiling was painted by Francis Wheatley and the state banqueting table seats eighty people. The cost of this one room is recorded as £1,500 which equated to more than the cost of a substantial mansion at the time.
