A fully accessible hydrotherapy pool and multipurpose complex, delivered for the Ministry of Education on an operating special-school campus, with a precast concrete structure and a cast-in cultural design.
KDB Construction — Main Contractor
Wairau Valley Special School needed a purpose-built aquatic and activity facility for ākonga with high and complex needs: a warm, calm, fully accessible environment where hydrotherapy and learning could happen side by side.
KDB delivered the project as main contractor on a live, operating campus, sequencing the build around term time so teaching and student safety were never compromised. The result pairs a robust, low-maintenance precast concrete structure with genuine warmth: a cast-in cultural design set into the precast panels and woven into the façade.
See the galleryWairau Valley is a specialist school for students with high and complex needs. On a build like this, accessibility and sensory safety aren't features bolted on at the end. They shape every decision, from circulation and sightlines to the finishes underfoot.
The warm-water hydrotherapy pool is reached by a gently graded, fully accessible ramp with stainless handrails, so students can enter the water safely with support. Throughout, surfaces are slip-resistant, durable and easy to keep clean, and the spaces are kept calm and low-stimulation by design.
The complex is built around a precast concrete structure: large reinforced-concrete wall panels cast off-site, then craned and set into their final position to form the building's shell.
It's a fast, robust and low-maintenance way to build at scale, and well suited to a humid aquatic environment. Getting it right takes precision at every step: formwork, steel, pour and lift all have to be exact the first time.
A warm-water hydrotherapy pool sits at the heart of the complex, ringed by a generous, slip-safe concourse with clear sightlines for supervising staff. Natural light, calm tones and durable, easy-clean surfaces make it a space that works hard every day.
Running the length of the façade, a flowing kōwhaiwhai/koru motif is cast into the precast concrete panels, a permanent expression of identity and belonging woven into the fabric of the building.
Achieving crisp, repeatable relief detail in cast concrete is a craft in itself: formwork, mix and pour all have to be right the first time.

Alongside the pool, a large multipurpose hall opens to the outdoors through a full glazed gable end. Overhead, a rhythm of exposed tapered glulam beams carries the roof, each one shaped to follow its structural load so the engineering itself becomes the architecture.
It's the contrast that gives the room its character: the warmth and grain of the timber set against the cool precast concrete and steel, with daylight pouring through the gable to tie it all together.
