The shelters are transported flat, in one piece, ready to unfold and pop up in a matter of minutes, creating a robust home without the need for specialist tools, skills or foundations. Both shelters can be used for transitional to long-term humanitarian aid and can house a family of up to five until permanent housing can be rebuilt.
The Hush2 is engineered and modelled to resist category five hurricane winds of up to 200mph. It hinges down from its upright position into storm safe mode in seven minutes.
"Crowdcube is an amazing resource. We're looking forward to taking our business to the next level, making a real difference to people's lives" said Lucy O'Driscoll, executive chair at Extremis.
Managing director, Julia Glenn, added: "Helping to overcome the problems faced by people affected by earthquake, hurricanes and floods, Hush shelters are also the starting point for rebuilding community. This next round of funding is needed to enable us to move into test deployment."
