The complex was established in 1972, when Bob Potter bought Wharfenden House and the surrounding grounds and lake. He soon doubled the hall to 1,000 seats principally for hosting comedians and musicians, including North American and internationally acclaimed acts. Lakeside was almost completely destroyed in a fire in November 1978, but was subsequently rebuilt, reopening in October the following year. During the 25th year of hosting the
World Darts Championship, in 2010 the lake had largely iced over by 7 January. That day the body of a man, a hotel guest for the competition week, was found.
Landowner-managers, Bob Potter Leisure Limited, were fined £85,000 for health and safety violations. Bob Potter died on 14 April 2023, at the age of 94. ==Events==
