The idea of using drone spraying really came from a background in earth architecture. We aim to deliver architectures that use natural materials, locally sourced, and to combine them with robotic fabrication, including drones. What is quite funny in the case of MuDD Architects is when we started two years ago doing the drone spray installations, you know, it was heavily criticized, mocked. And slowly, right now it feels a lot of people say, “It’s so obvious, it’s obvious that you’re doing this and it is really, you know, efficient.” Even if you’re doing it small scale — because a lot of people are like, “just take a ladder,” you know, “and spray.” It’s not exactly true because even if you need to take a ladder and carry the pump that is really heavy and you need to replace the ladder every one meter that you need to do the facade, whereas, like, you know, the drone can do it and, and carry the heavy pump, and do it with such dexterity and such speed that at any scale basically, according to us, it is more efficient. But we did really notice the shift between two years ago where people were like, “Yeah, that’s crazy.” And now it’s like, “Yeah, it’s obvious and you know, anyone can do it.” The Brussels mural was really an important project for us — probably the most important of all — because of its simplicity and just the message that we would like to pass. For us, that was a really good context to showcase that the drone spraying could be used for facade refurbishments, including ornamentation, in the very city center. The event was only set in four hours. Like, the drone spraying was really to showcase that we could do a facade refurbishment in just a few hours. In any urban context, might be in Paris, Milan, we can just lift up some nets very easily. And within the net, we are authorized anywhere in Europe at least, to do those kind of drone spraying activities. Our aim really is to showcase to the world that we can actually do these kind of facade refurbishments with the drones without any authorization from the aviation laws. It comes from a very simple consideration about being able to spray huge surfaces, or difficult to access, or nonregular geometry without the need to build labor-intensive, cost-extensive scaffoldings. That in some projects, you know, scaffoldings end up being the same price as the construction itself. So we realized that basically there was immediately available technology, but there wasn’t yet combined together. The drones already can carry a lot of weight. So the one that we are using and that we have fine-tuned for the project can carry 40 kilos, so it’s quite a bit, but some drones can carry much more, can carry a person, 90 kilos — it is really mainstream already, drones that can carry up to 100 kilos.
