the winners for the 20*20 prefab competition have been announced.

take a look at the website to see some of the winners & honorable mentions : http://prefab2020.wordpress.com/ .

My entry, unfortunately did not make it into the shortlist. below are some images (bottom of post) from the entry, as well as, the key ideas behind the design.

description: trillions of mountain pine beetles have killed over 500 million cubic meters of lodgepole pine in british columbia. in order to salvage value from the dead trees, generous logging quotas have been established for the lodgepole pine. the mountain pine beetle transmits a fungus that stains a tree’s outer growth rings a blue-ish tint. this discoloration has no effect on the structural integrity of the wood. the mountain pine beetle lives most of its life under the bark. in the winter, the temperatures have been too moderate in bc to kill off large portions of the beetle population and the spread of the infestation has grown dramatically. this is an example of a pre-fabricated home that utilizes this wood by using it in its building and its components; allowing functional living and reducing an ecological and environmental impact.
