How to build a house with a drone

<pre>How to build a house with a drone

Stephanie Chaltil from the Barcelona Institute of Advanced Architecture (Spain), specializes in automation techniques for various aspects of construction. Its latest development is devoted to the construction of simple functional houses from “bio-cement” – a modern version of mud and clay huts from the ground and reed. A key design element that holds all bio-cement together creates multicopter with pumps.


The basis of such a structure may simply be a geodesic dome or a structure with a frame made of branches-tubes and fabric stretched over it. Any suitable material with adhesive properties acts as bio-cement. It may be a combination of sand and oil, sawdust and fuel oil, a thin clay solution, even the most common dirt. The main thing is to ensure the possibility of pumping the substance through the tubes so that the multikopter can lift the nozzle to a sufficient height and spray the liquid over the base.


As an experiment, the team Chatil built the first house from the geocase, 2000 jute bags with hay and mud bio-cement, which took them only an hour of work. The building collapsed a week later, but by that time the miscalculations became clear and the new house was built more slowly, controlling the thickness of the sprayed layer of dirt, so that a solid cover was formed. This building stood all summer, and its copy was presented at the London Design Festival.

The main advantage of the technology is that the construction of the building does not require forests and sophisticated equipment. The drone will deliver portions of bio-cement to any desired height, and if you write for it a program to control the thickness of the sprayed mixture, it will be able to create ideal coatings without human intervention. Extremely cheap, practical technology for warm regions of the planet.
