Te Wānanga-O-Raukawa, a Māori tertiary institution in Ōtaki required a building to fulfill its vision for courses focused on improving physical wellbeing for Māori. The brief called for 2 indoor courts, cardio gym, nutrition teaching kitchen, classrooms & academic offices.
The design strategy uses the holistic model of Māori health ‘Te Whare tapa Whā’ (four sides of the house) to generate the form of the building. This model addresses the need for physical (tinana), mental (hinengaro), spiritual (wairua), & social (whānau) aspects of life all to be in balance for wellbeing. The design represents this model with a folded roof creating spaces with associated functions leaning against the neutral form of the sports hall.
Timber was used extensively for structure, Engineered timber, laminated & LVL, was used for post, beams & rafters. Within the sports hall a 36m span Tahuhu (ridge beam) with a precambered composite timber & steel beam which aesthetically represented a waka & minimised the bulk of the structure.
