The earliest school building is likely to have been on the site of the current school library. The library was built in 1716 and had a simple wooden upper storey inside. This drafty building was heated with one fireplace which the sole master sat beside. The pupils sat in rows with the oldest boys closest to the teacher and the fire, whilst the youngest boys sat at the farthest end of the room. The library is a much more welcoming building now which includes scholars’ booths and private study areas.
The oldest boarding house, Evans House, was built around 1750 as a private house. The headmaster Christopher Hull lived there and took in private boarders. When he died the school bought the house and continued the tradition of the headmaster living in Evans house and taking in boarders. Local tales suggest that a secret tunnel links Evans House to the church next door and that Bonnie Prince Charlie used this to evade capture during his journey through Sedbergh.
In around 1870 the school numbers dropped to only 9 pupils and headmaster Heppenstall was brought in to transform the school. He believed that the school needed to increase in size dramatically to secure its survival. At that time the school estate consisted only of the library building and Evans House. Heppenstall commissioned a firm of well-respected architects, Paley and Austin, to design the Victorian Main School buildings and three purpose built boarding houses, School House, Hart and Sedgwick. Heppenstall formed Sedbergh in the model that still exists today. He established the architectural style of the school, introduced rugby in 1879 and started the Sedberghian magazine in the same year. During this period of change Lupton House was built in the town. The three separate town houses were rented by school initially and then converted to form one character filled building.
Worship for Sedbergh pupils originally took place in St Andrews Church, however the expansion of the school during the 19th century meant that the school could no longer be accommodated at town religious services. The new chapel was completed in 1897 and features yellow sandstone on the exterior and red sandstone on the interior. The building is fitted with many stained-glass windows that fill the space with shafts of coloured light when the sun shines.
