Historical buildings report The original school was built by 1826 and consisted of two large classrooms for up to 80 children each and two smaller classrooms for 23 children. The Master's House was built on the back. The main entrance was through the north porch and undoubtedly the school was split in half for boys and girls. The quality of the brick and flintwork walls is exemplary, in particular the attention to detail in the brick dressings and Tudor style labels. The large windows mimic Tudor and Gothic architecture with lancet frames and intricate glasswork. In 1826 it is highly likely that all the windows were leaded lights of which the only remaining complete example is Window 35 on the Octagonal Office. Historical mapping shows that the Octagonal Office was not part of the original building and was added as part of the 1877 additions when the Master's House was enlarged and the Infant's School wing added. This means Windows 1 and 35 (which are the same) are reused and it is most likely they were taken from the earlier rear porch shown on the 1836 map. By 1877 large panes of glass were economically available and it is more than likely that the school was furnished throughout with the large pane windows in place today. Windows in good condition would have been retained as long as possible but it is evident that there was a large scale re-fenestration in the 1930's. Most of the windows have modern glass, inserted bottom hung vents and casements with rat tail catches and stays of a design very popular in the 1930's. There was also a fashion for leaded lights and a large industry could easily supply. The casement of Window 35 has been repaired with 1930's style lead cames. However, the windows were expensive, heavy, difficult to clean and maintain and restrict the incoming light. At the School, economies are evident in the presence of 1930's style Crittall windows with rolled steel galvanised frames. Crittall also offered (and still does) a service for refurbishing older windows and some of the lancet windows have rolled steel casements of the 1930's. The main stylistic difference is the use of landscape panes - a hallmark of the International Moderne style that Crittall promoted.
