An area of Horsham named after a feeder stream of the River Arun. It consists of residential housing, the majority of which is of late 20th-century origin. The suburb is substantial enough for two council wards. The hamlet around Old Holbrook House is immediately to the north of the A264, which abuts Holbrook. Holbrook House was previously the home of Sir William Vesey-Fitzgerald, Governor of Bombay and M.P. for Horsham (1852–1875). The Tithe Barn at Fivens Green is the most notable building in the district.
