Forty Wall House

Background

In an attempt to address the current housing and environmental crises, in July 2021 we completed the Tasmanian House, a prototype of a small, economical cabin, built from raw, locally sourced materials, minimising the use of imported or synthetic materials and entirely avoiding all paints and other chemical treatments.

The cabin is incrementally extendable, to eventually serve as either a larger family home or two separate residential units. The prototype is part of a long-term cohousing / ecovillage vision and the plans have also been made freely available to the public.

Forty Wall House is a continuation of the Tasmanian House.

Experiment

The Forty Wall House is a live, lived-in, open source experiment, an attempt to fast-track sustainable material testing, certification and adoption by rapid prototyping.

Its massive timber frame is wrapped in a curtain wall consisting of 40 independent panels. Each of the panels is clad, insulated or filled with an innovative experimental material, subject to constant monitoring. Failed ideas are replaced with new ones on the go.

Far from isolated laboratory conditions, the house is located in Northern Tasmania in one of Australia’s most variable climates, with snowstorms, gale force wind and heatwaves and permanently inhabited, subject to intensive traffic and scrutiny.

Discourse

The Forty Wall House is currently under construction, with expected completion in early 2022. The construction progress, learnings and results will be published on this website and other channels.

The project is open source. Anyone is invited to contribute ideas, materials and technology to the experiment.

All findings and the resulting IP will be released into the public domain under the Creative Commons licence.
