Light Timber Construction schools, as the name suggests, were constructed using wooden framing. External walls are either clad in timber, sheet metal.
Rooftops were always clad with corrugated iron, and supported by zig-zag steel rafters. LTC schools were always built as a single storey. Where multiple school wings were required, buildings were often linked with an iron covered-way in the case of primary schools, or a link corridor in the case of high schools.
LTC school buildings always consist of long central corridors, from which classrooms are constructed on either side. Typically, there will be a continuous span of classrooms on one side, whilst intervals will be left between clusters of classrooms on the alternate side, to allow for additional exits and natural light to penetrate the corridor. Occasionally, classrooms will only be constructed on a single side. Corridors typically have low ceilings (approximately 3 metres), and capacity for bags (primary schools) or lockers (high schools) to be stored along the walls. A long series of windows provides visual contact with classrooms.
Classrooms are typically entered through sliding doors from the corridor. The ceilings of classrooms are elevated above the corridor, and tilt away so that one row of windows connects the room with the corridor, whilst another row above provides natural light from outside. On the external side, either two or three horizontal rows of wooden-framed windows provide light from outside. LTC classrooms were typically furnished in a uniform way, with built-in blackboards and cupboards at the front of the room, fluorescent lighting from above, and venetian blinds on the windows. Most classrooms had polished wooden floorboards, which were later carpeted-over.
