The building is a narrow extruded form; teaching spaces are located over four levels accessed from external timber screened walkways. The stepping walkway section which increases to up to 5.5m in width is designed to provide additional external teaching spaces and allows building occupants flexibility to respond to varying climatic conditions. Reflected daylight is bounced in to the plan by angled coloured fin blade walls on the eastern façade, this moderates light levels and provides an individual character to each classroom, whilst also controlling solar gain.
The proportion and orientation of the building provides all spaces with dual aspect promoting cross ventilation, which in conjunction with exposed high thermal mass surfaces, solar control devices and ceiling fans provides a high degree of thermal comfort. The roof which runs the length of the site collects and recycles rain water.
It was agreed from an early stage that a school should be a lasting stable structure in repose and that it should stand largely against time though with the accumulation of a material patina. To this end the materials were selected and the construction was composed to achieve a robustness tempered by a material and chromatic warmth and with a poetic playfulness that was considered appropriate for such an institution. Stretching a penny with all of the project team, a school was made and it is the architects' hope that all who attend will be inspired by and recall fondly the experience over the next hundred years.
