Practice Architecture worked alongside hemp farmers to erect this zero carbon home in Cambridgeshire, England, from pre-fabricated panels in just two days.
Flat House is located on Margent Farm, a 53-acre farming facility in rural Cambridgeshire that aims to show off the capabilities of hemp ? a fast-growing strain of the cannabis plant.
Hemp is already used commercially to manufacture everything from clothing to biofuel. It's increasingly being employed as an eco-friendly building material because of its ability to sequester carbon.

Margent Farm cultivates its own supply of hemp, and challenged Practice Architecture to use the plant to create an on-site residence with "incredibly low embodied carbon".
The resulting house is also off-grid, with heating and power provided by a biomass boiler and a photovoltaic (PV) array ? a system of solar-energy panels ? on the roof.
The architects are currently awaiting paperwork which confirms that the home's design means it's zero-carbon.
According to Practice Architecture, the zero-carbon measure is typically assessed by the lifetime carbon cost of a building, rather than the embodied carbon levels at the time of construction.
Whilst they would favour use of the latter benchmark by the industry, they are more concerned with the materials used to build Flat House than the zero-carbon designation itself.
"The radical thing about the building is not so much it's zero-carbon status but more the use of naturally grown mater...
