UK-based Blue Forest makes inventive tree houses and recently introduced a new design concept called the eco-PERCH, which I think you’ll be interested in seeing. The four-bed retreat can be delivered, assembled, and commissioned in about five days with things like photovoltaics, a composting toilet, and rainwater harvesting, etc.
Sustain Design Studio, creator of the original and enormously popular miniHome, recently announced a new design called caliMini made specifically for the western United States. CaliMini will be built in California and offered in four models ranging in size from about 611 – 1,190 square feet (not counting the loft). Plus, one of these eco-friendly, contemporary homes will be on display at Dwell on Design 2012 in June, according to Sustain.
As mentioned a couple weeks ago, Oregon-based Ideabox created a new prefab in collaboration with IKEA Portland for the Portland Home & Garden Show going on right now, February 22-26, 2012. In case you’re not in the area, here are some photos of the fresh new home. Ideabox Aktiv features tons of IKEA products and showcases a cost-effective home that can be built with open spaces, vaulted ceilings, and clean lines.
