The South Half of the Main School Buildings Tonbridge School

The South half of the main School Buildings at Tonbridge School was built in 1864 and designed by architect E H Burnell. This structure is a notable example of mid-Victorian "Gilbert Scott" Gothic architecture. It stands three storeys tall and features twelve windows, constructed from sandstone ashlar. The building has a castellated parapet and a blue slate roof, which includes two horizontal lines of five courses each of green slates inserted along the center.

The building is divided into two sections by a small central tower. The south section contains six windows on the ground floor, each with three trefoil-headed lights and stone mullions. The first floor has square-headed windows with stone transoms and mullions, while the second floor features pairs of trefoil-headed lancets. The tower rises four storeys and is supported by buttresses at the corners, with a four-light oriel window on the first floor.

The north section has six pointed windows, each consisting of two trefoil-headed lancets that extend from the ground to the first floor. Additionally, there is one window bay with square-headed windows on both floors, each containing four lights with two transoms. The second floor of this section is adorned with fourteen trefoil-headed lancets.
