PROJECT DESCRIPTION

Cross Laminated Timber Manufacture

This scheme fuses commercial material production with an open

learning environment. The program caters to full scale Cross Lam-

inated and Laminated Veneer Timber manufacturing with space

for the public and research groups to actively participate in the

development of the products.

The building sits on the corner of Durham Street and Moorhouse

 Avenue in Christchurch, on an empty site. It falls within the indus-

trial zone running east to west through the south of the city’s out-

skirts, and takes advantage of exposure from the tw o main roads

forming the north eastern corner.

 At just over 10,000sqm the building offers a large space for CLT

and LVL processing. This takes up the majority of the ground

oor, while an exhibition space, cafe, seminar room and ofces

hover above.

I developed a material investigation into the micro and macro

structural composition and function of wood cells. Nutrient circula-

tion and cell transformation helped to develop a spatial language,

and informed the building’s circulation.

The built form effectively allows for parallel movements of both

manufacturing and a learning environment, visually connected but

with respect for the functional demands of each program.

FOREST COMPOSITION

WOOD PRODUCTION AND USE

SOFTWOOD

- predominantly from conifers and evergreen

trees

- seeds uncovered

- non porous structure

- simple cell -ranges in density and not nec-

essarily softer than hardwood

HARDWOOD

- predominantly from broad-leafed and de-

ciduous trees

- seeds within a ripening

fruit

- porous structure- more complexity and variety in cell structure

HEARTWOOD

- all cells in heartwood are dead

- often darker in colour than sapwood

- often highly decay or insect resistent

- may be difcult to penetrate with liquids

- may be difcult to dry

- no strength difference between heartwood

and sapwood in almost all species

SAPWOOD

- living cells only found in sapwood

- inner region serves to transport water up and down

the tree

- often lighter in colour

CROSS - LAMINATED TIMBER

There is currently only one factory producing CLT in the whole of Australasia, situated in

Nelson, New Zealand. CLT is an engineered wood made mostly from softwoods which

are fast-growing and are weaker solid timbers. The lamination process strengthens the

wood immensely. It can be used as a structural system in itself, or in conjunction with oth-

er systems. The material promotes building structures with large quantities of low-grade

timber, sequestering huge amounts of CO2. All panels are manufactured in factory con-

ditions to accurate dimensions ready for installation. This reduces time, costs and emis-

sions related to lengthy on-site construction. CLTperforms very well under seismic loading.
