built for the sum of £2,240. Hurst Road Site By the late nineteenth century, the population of Horsham had expanded to 10,000 (accelerated by the coming of the railway and its associated employment), the City and Guilds Institute (which the Mercers' Company had helped found) decreed that education needed to be extended to include the new sciences, and money needed to be found to replace the school buildings yet again. Thus after a long campaign against fees, including a petition of 1,100 signatures, the new school charter of 1889 stated that, “Tuition fees might vary between £4 and £10 p.a. and Boarding fees were not to exceed £40 a year.” A new and larger site was sorely needed. The present site in Hurst Road was found, and the current building was designed in 1892 by Arthur Vernon, and built by Joseph Potter in 1893 for a contract price of £5,795. It is now grade II listed by English Heritage. Above the entrance is a stone engraved with, “Grammar School, Founded by Richard Collier AD 1532”. (Historically the founder's name was often spelled as ‘Collier’, but from the twentieth century it has always been spelled as it is today.) The 1892 building facing Hurst Road has been extended continually as the school has expanded. This included the addition of science laboratories in 1897, a ‘Great Hall’ in 1912, and the ‘New Block’ classrooms in 1932. In the 1890s Collyer's taught 110 boys from ages 7 to 17, both boarders and day-schoolers, and for the first time included a sixth form to study for university entrance. From 1923 the Rev. W. M. Peacock started to model the school on public school lines, introducing (among other things) four houses (see below), The Horsham Grammar School Magazine (later to become The Collyerian), and a school song. By 1926 it was a single-stream school of 220 boys with a sixth form of “less than a dozen”, and ten teaching staff. Grammar school Collyer's ceased to accept boarders in 1935, and the dormitories were converted into much-needed library and common-room space. Plans for adding a gymnasium and other facilities were abandoned in 1939, when the school accepted evacuees from the Mercers’ School in London, and pupil numbers soared to over 400 in three streams. (The accommodation crisis was solved by building hutted classrooms, but numbers continued to rise because of the post-war ‘baby boom’, and the
