Big Designs 180 Square Feet Tiny House for Prefab-Housing Startup Klein 

The world-leading architecture firm Bjarke Ingels Group (BIG) , in collaboration with the prefab-housing startup Klein, has designed a tiny house prototype named A45. The design evolves from the traditional A-frame cabin, known for its pitched roof and angled walls, which allow for easy rain runoff and simple construction. The diminutive dwelling has been constructed in upstate New York and will be customizable inside and out for future homeowners to purchase, tailor, and have built within 4-6 months in any location, for any purpose.

To maximize the qualities of this classic structure, A45 creates more usable floor area by starting with a square base and twisting the roof 45 degrees, raising the tiny home to a soaring height of 13 feet. The resulting crystal-like shape gives A45 an ever-changing appearance.

Upon entering, the 180-square-foot interior space reflects a minimal Nordic abode, prioritizing ‘hyggelig’ comfort and design. From the exposed timber frame in solid pine to the Douglas Fir floor and customizable space-grade insulating natural cork walls, A45 brings nature inside. An elegant Morsø wood-burning fireplace is nestled in one corner, while off-the-grid equipment is tucked away in the back.

A petite kitchen designed by Københavns Møbelsnedkeri, hand-crafted furniture from Carl Hansen, and a bed fitted with Kvadrat fabric designed by Soren Rose Studio are some of the handcrafted Nordic furnishings that adorn A45.

A45 is assembled in modules on site and consists of 100% recyclable materials, including the timber frame, wall modules, subfloor, and the triangular floor-to-ceiling window featuring seven glass pieces that allow natural daylight to illuminate the interiors. The structure is slightly elevated by four concrete piers, providing optimal support and enabling homeowners to place their tiny house in even the most remote areas without the use of heavy machinery.
