Bjarke Ingels Group Designs First Tiny Off-Grid House ‘A45’

Architecture firm BIG has built a compact black cabin with an angular roofline in the Hudson Valley, as the initial model for prefab-housing startup Klein.

The Bjarke Ingels Group has developed a hut which can be individualized and be built quickly in any location. Known as ‘A45’, BIG designed the dwelling using a layout that efficiently utilizes the useable space by using a square base of 17 square meters and twisting the roof by 45 degrees. This allows the tiny house to benefit from a ceiling height of 4 meters.

The project is an version of the traditional A-frame cabin, recognized for its pitched roof and angled walls. Built in upstate New York, the micro home is designed for Klein, founded by designer and interior architect Søren Rose.

Inside, Nordic influences shape the interior with exposed timber frames, Douglas fir flooring, and a cedar sauna-styled bathroom while floor-to-ceiling glazing puts you upfront with nature. Along with its wood-burning stove, the entire structure operates off-grid and is made entirely from recyclable materials.

“When you go into the woods, you actually want to get into the woods,” Ingels explains. “A home that’s incredibly compact ensures that nature is what you end up experiencing.” The prefabricated cabins are intended to serve the growing number of city dwellers wanting to escape to nature, such as the micro home by Japanese brand Muji.
