History
In 1913, the Grosvenor Hall estate in Kennington, Ashford, Kent, was acquired by Percy H. Jones, who repurposed the Victorian-era mansion as a sanatorium dedicated to treating tuberculosis. Jones transferred patients from an existing facility he operated, adapting the estate's grounds and buildings for the open-air regimen central to early 20th-century TB therapy, which prioritized fresh air, sunlight exposure, rest, and nutritional support over pharmacological intervention. The sanatorium opened around 1915 and quickly served military needs during World War I, accommodating soldiers and sailors invalided by TB contracted in service conditions.
Operations emphasized isolation to prevent contagion, with patients housed in purpose-adapted wards and verandas designed for heliotherapy and graduated physical activity to rebuild lung function. By the interwar period, it functioned as a civilian TB facility under local health authorities. In 1948, the sanatorium joined the National Health Service and was renamed Harts Hospital, operating with 98 beds.[2] Post-World War II, the sanatorium's focus shifted as antibiotics like streptomycin (introduced 1944) and isoniazid (1952) dramatically reduced TB mortality and hospitalization needs, rendering prolonged sanatorial stays obsolete. Operations wound down, with the facility closing in 1955 amid national healthcare reforms prioritizing outpatient drug therapy over institutional isolation.
The Grosvenor Hall estate in Ashford, Kent, was purchased by the Home Office in 1973 to establish a District Police Training Centre (District 6) for regional police training needs. Prior to this, the site had been acquired by the Metropolitan Police in 1961 for cadet training. The Ashford Police Training Centre at Grosvenor Hall closed on 26 May 2006, concluding its role as the primary facility for initial training of police recruits from South East England forces, including Kent, Surrey, and Sussex, over a period spanning from 1973.[1]
In September 2009, Kingswood Educational Activity Centres completed the purchase of Grosvenor Hall and surrounding land from the Home Office, following the site's closure as a police training center. Redevelopment efforts focused on restoring the 65-acre estate, including clearing overgrown grounds that had deteriorated during prior vacancy, refurbishing existing buildings for accommodation and operations, and adding new infrastructure such as a 50-by-100-meter figure-of-eight lake with viewing platforms for water sports activities. Grosvenor Hall, operated by Kingswood until its administration in 2025 and subsequently acquired by PGL in January 2025, spans 50 acres of grounds surrounding a former manor house and accommodates up to 1,074 guests in dormitories, lodges for children, and en suite single or twin rooms for adults.
