Henry Vickers and the surgeon Dr William Jackson Cleaver, issued a statement saying it was “expedient to found an institution for the relief of poor sick children”. The Children's Hospital opened on 15 November 1876 in Brightmore House at a rent of £63 per annum. Webster served on the hospital's management committee for many years overseeing its expansion, when the hospital moved to new buildings on Western Bank in 1902 he acted as architect, completing the building in red brick Tudor style with tower. Webster designed the Jessop Hospital for women in 1878 in late Gothic style "with some strange detailing", it is a grade II listed building which now house the University of Sheffield Music Department. Webster returned 24 years later and added an Edwardian extension of additional wards (1902). The Grade II listed extension was controversially demolished in 2013, despite vigorous protests by The Victorian Society and the Hallamshire Historic Buildings Society to make way for “The Diamond” a new £81 million building for the Department of Engineering. Other hospital related buildings by Webster include the Medical School on Leopold Street in 1888. He oversaw extensions to the Ecclesall workhouse which included a new male ward block (1891) and infirmary (1894), the workhouse would later become Nether Edge Hospital. Webster also carried out extensions to the original Sheffield Royal Infirmary at Upperthorpe, he added the Outpatients Department in 1884, an innovative octagonal structure now known as the roundhouse, it was influenced by advocates of the circular hospital ward. He also added the Nurses Home (Centenary House) in 1897, both the infirmary buildings are now Grade II listed buildings. Other work The early days of the practice in the 1870s saw much work being done designing private houses in the developing, affluent Sheffield suburb of Ranmoor. The best two examples are West Lea (1870) and Ranfall (1871) on Ranmoor Park Road, both are built in a conservative, classical style typical of Sheffield at the time. He also designed a dignified Italianate lodge at 83 Ranmoor Road (1874). Storth Oaks at 229 Graham Road was built in the late 1860s as a private house in the Swiss-Italian style, it is now a treatment centre for adults with drug and alcohol problems, it is a grade II listed building. Webster carried out extensions to Totley Hall in 1883 and 1894 which included a billiard room with a 4-light stained glass window.
