One tenet of sustainability is to use space and material efficiently, an idea exemplified by entries in a design competition sponsored by Poland-based global skylight/roof window manufacturer FAKRO (possibly another opportunity for student design competitions). The competition, called New Vision of the Loft 2, asked entrants to “design a functional space full of natural light, using highly energy-efficient technology in order to create unconventional loft concepts, where light and space play major roles” and use at least 10 FAKRO roof window products.

A Danish-based team of  German Ole Robin Storjohann and Poland-born Mateusz Mastalksi proposed “Live between buildings” narrow, suspended lofts in the gaps between buildings, .

Is this a denser, more sustainable vision for the future? Should the gaps be used for spaces other than personal residences? What other nooks and crannies can we fill up–and should we? This is a common tension in sustainable design, finding the right balance between maximizing efficiency and functionality and leaving enough space for urban ecosystems and urban nature that can help densly populated places “breathe,” grow food, absorb waste and produce energy. What answers will your students give?
