Paloma Gormley with Practice Architecture
The house was designed to demonstrate how a low-tech approach and bio-based materials can be combined with offsite construction to create a scalable low-impact, beautiful architecture. The careful orchestration of natural materials creates a building that regulates humidity, temperature and air quality without the need for any ducting or equipment. The house draws from centuries old material technologies and construction principals, re-rationalising them for contemporary building techniques.

When sourced locally natural materials are inherently low carbon as less energy has gone into their production than contemporary highly processed materials. Plant based materials such as timber and hemp sequester carbon whilst they grow meaning it is stored within the fabric of the building. Furthermore these materials can be returned to the ground without doing any harm, creating waste or poisoning the environment. The house comes from an interest in “circular ecology”
an attempt to describe the idea of buildings as things that are integrated into agricultural processes – that emerge from and eventually return to the landscape that created them. It feels increasingly clear that we cannot address sustainability in architecture purely through reducing operational carbon. The building consists of a radically low embodied carbon timber and hempcrete structural panel. Whilst the house has been designed for residential use and with the constraints of Class Q permitted development the system has the capacity to be used for any type or scale of building.
Situated at Margent Farm, a rural R&D facility developing bio-plastics with hemp and flax, Flat House is a ground breaking radically low embodied carbon house. The three bedroom house was designed with the aim of prototyping prefabricated sustainable hemp-based construction to be applied to larger scales of house-construction. Working closely with engineers and material specialists we developed a prefabricated panel infilled with hemp grown on 20 acres of the farm. The elements were raised into place in just two days.
