Covering a 734 sq m area, Ockendon Academy’s extension comprises seven new classrooms, plus associated support areas and a large open learning zone.
Timber design and construction company Cabinco worked with quantity surveyors, JTS partnership to create a sustainable building that would feature lots of natural sunlight. This included a complex split roof design, large windows in all classrooms and a glazed open learning zone, ensuring good levels of light even in the corridor.
Using timber helped to maintain the structural integrity of the complex roofing system, while meeting the high sustainability standards required. Prefabricating the timber solution offsite also allowed the build programme to be completed in just 20 weeks on site.
A further challenge was achieving good acoustic attenuation in the building – a tall ask given the large amounts of glazing and other hard surfaces which would refract noise. The design team were able to meet BB93 standards for schools through use of innovative, mitigating solutions, including creating ‘cavities’ in the internal walls which were filled with acoustic slabs, and using specialist rubberised strips above and below the classroom walls.
A total of 266 m3 of timber went into the new school. Calculations show that the timber has already sequestered 478 tonnes of CO2 during its growth.
