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).

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.

perceptions about alternatives to conventional
approaches to building & financing housing.

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.
