I've talked with Luke about this a bit, and one suggestion is that we need areas for the "dirty" work that goes with a lot of maker projects - cutting and welding metal, wood, plastics, etc. Painting also needs a sealed-off and ventilated space. Many of these activities are noisy, and spew dust and bits of stuff all over the place, so they need containment, from each other and from the quieter spaces for programming, 3D-printing, electronics assembly & testing, meetings, etc. They might be harder to present in such a beautiful video, though!
