‘Building A Martian House’ was a public art project conceived by artists Ella Good & Nicki Kent. Constructed in the Bristol docks, in the west of England, it brought to life a full scale Martian House, designed through a collaborative process between artists, scientists, architects, engineers and the public. The lightweight house was designed to withstand the Mars environment. The upper level was formed using a pressurised inflatable gold-coated foil which, on Mars, would be filled with Martian concrete made of regolith (soil) and water found below the surface. The lower level would be built underground within the lava tubes that exist beneath the planetary surface. The interior of the Martian House was developed through workshops with the public. The project provided an eye on our life on earth, demonstrating the need for recycling and reuse to limit environmental impacts.
