designed by Bjarke Ingels

Designed by world-renowned architect Bjarke Ingels and winner of the American Institute of Architecture Small Space Projects 2019 the free form shape and expansive windows of the Klein A45 gives you all the space you need to enjoy an infinity of possibilities.
With the Klein A45 Bjarke Ingels and I decided to take everything we learnt from high-end residential and boil it down to the essentials.

Meet the architect
behind the Klein A45

Ever since he founded BIG in 2005 Bjarke Ingels has designed and completed award-winning buildings worldwide. He defines architecture as the art and science of making sure our cities and buildings fit with the way we want to live our lives, a core belief that has clearly come to life with the Klein A45.

Built for fun,
for work, for life

The Klein A45 easily accommodates a small family on holiday or guests visiting, it’s a flexible office space for writing and singing or simply the perfect hideaway for a natural break from everyday life. And no matter if you're located in the woods, the mountains, along the shore or in an urban setting you can enjoy your Klein A45 tiny house all year long.

What makes
the Klein A45 special?

Built on a fundamental belief in sustainable and small space living, the Klein A45 is constructed primarily using certified materials and an optimized process that ensures zero-waste production wherever and whenever possible, and in individual sections to fit as little as possible when shipped. The Klein A45 is designed to connect to your local utility grid, however, we aim to develop a system called BIOS, that will enable our tiny houses to be fully functional with any off-grid installations if you desire to do so.


We work to find the right solutions that can ensure the most environmentally friendly solution for our A45 house. Therefore, we seek to work with high-end technology that can make the building process more efficient and ensure that the assembly of the house happens in a controlled environment. The purpose is to reduce as much waste throughout the building process as possible.

We will work with structural insulated panels with an exterior ZINK cladding. These panels are one of the most advanced, sustainable, and cost-effective construction solutions on the market. Structural insulated panels, or SIPs, have high performance insulation and energy efficient qualities. The purpose of building with SIPs is to ensure a sustainable and environmentally friendly building, as structural insulated panels are designed to reduce energy consumption, conserve resources and create a healthy indoor environment.
