Technology

Wood Processing A saw guide and production bench, used in combination with almost any hand power-saw of 162mm or larger, can process all the framing timber, including rebate and angle cuts.
	Panel Making The cut timber is laid within a limit-jig and nailed together to form frames. Building paper & external plywood cladding is added. While horizontal, the panels are coated with acrylic paint. This way of painting maximises absorption into the plywood resulting in a plastic-like finish.
Panel Assembly At wall intersections, a tongue and slot in each panel, allows the panels to lock together before nailing.
	Internal Wall Assembly The tongue and slot system applies when internal wall- panels join. The timber framing for floor, wall, ceiling panels, the roof frames, sub-floor bearers & and lintels - is one size of timber (100mm x 50mm Pinus Radiata).
Ceiling/Roof Framing Preparing for the roof, showing roof-framing gussets made from off-cuts of plywood external cladding. The workers stand on plywood ceilings to work safely.
	Preparing for Roof Preparing for the roofing on a single storey starter house.
Ceiling Panels Upper-ceiling panels of a two-storey house in position and ready for roofing.
	Interior A view of the livingroom/dining space of a typical house, showing the panelised plywood ceiling and fibre-glass wall insulation.
Roofing A nearly completed "Onduline" roof - a paper-based roofing material impregnated with bitumen.
	Interior finishing A view of an upstairs bedroom space of a typical house, showing oil-stained plywood ceiling panels.   top

 

 Training

Housing School Participants are introduced to an Accelerated Learning Programme (ALP), which starts with the building a 1/5th scale model from a set of house plans and using prepared-to-scale building materials.
	Accelerated Learning Programme A team exercise in model-building helps the participants to learn the language & concepts of the building technology and methodology. A team is shown completing the exercise by assembling their scale-model house.
Transfer of Learning Using models helps to explain the ceiling/roof-frame system used in CHAANZ's house designs.
	Processing Timber Members of the Just Housing Otepoti Trust (Dunedin,NZ) being introduced to saw guide & framing-timber cutting system. The system enables the inexperienced to process timber safely, quickly & accurately.
Panel-Making Jig A limit-jig ensures that the timber for making frame of the panels has been cut accurately. Picture from an early Housing School attended by representatives from Ngati Kohungunu (Hawke's Bay), Ngati Whatua (Kaipara), & Tuwharetoa (Rotorua/Taupo).
	Panel Building A class of Year 10 students from Papakura High School, learn to position & fix plywood to the framing timber of an external wall-panel.
Wananga Using models to explain the building system during a one-day learning seminar in the regions. Part of the work of changing perceptions about alternatives to conventional approaches to building & financing housing.	top

  Research

Relocating Houses An important feature of the CHAANZ panel system, is an ability to construct modules which can be easily transported to the house site and assembled there ready-finished. The picture (right) and those that follow, are from development work to implement this concept.
Relocatables (Series 2) Houses that are easy relocate make possible the use of surplus community land as sites for community rental housing. If the community land is required for another use, these houses can be split apart, and cheaply re-located.
	Factory-built & ready to Shift. A house built as a relocatable, can be unbolted down the middle (see photo above) and trucked to a prepared site.
