Klein A45

Owner: Live Klein

Location: New York, New York

Category: Up to $150,000 in construction cost (category one)

Klein A45 is a completely off-grid sustainable tiny house designed for quality living and built with the highest standard of craftsmanship.

Klein A45 is the first prototype constructed in New York and will be entirely customizable for home-owners to purchase, tailor and have the tiny house built within 4-6 months in any location, for any purpose. The design evolves from the traditional A-frame cabin: A45 increases usable floor area by taking a square base and twisting the roof 45 degrees to raise the tiny home to a soaring 13ft height. Upon entering, the 180sqft interior space reflects a minimal Nordic abode: from the Douglas Fir floor to the insulating natural cork walls, A45 brings nature inside. An elegant Morsøe wood-burning fireplace, a petite kitchen by Københavns Møbelsnedkeri, hand-crafted furniture from Carl Hansen and a bed fitted with Kvadrat fabric designed by Soren Rose Studio adorn A45. The bathroom is made of cedar wood with fixtures by VOLA. A45 is assembled in modules on site and consists of 100% recyclable materials.
