Bjarke Ingels Group has revealed images for the firm’s first-ever tiny house—the A45—designed for the prefab-housing startup Klein. Inspired by the traditional A-frame cabin, the A45 takes on an angular form conducive to rain run-off and easy construction. The 180-square-foot timber cabin boasts a completely customizable interior design and can be built within four to six months in any location. Constructed in Upstate New York, the prototype for the A45 tiny house is clad in blackened pine with a triangular glazed end wall to immerse homeowners in nature even when they’re indoors.
