The Grey Hour

In his latest blend of reportage and essay, Filip Springer asks urgent questions about architecture in the age of climate catastrophe. If buildings and their life cycles account for nearly 40% of global emissions, how should we build — or should we build at all? Through interviews with architects and urban planners, Springer explores both reckless projects and inspiring innovations that suggest a more sustainable future.

One chapter is dedicated entirely to the Warsaw Uprising Mound Park, where he speaks with the designers from archigrest and topoScape. They discuss recycling in construction, the ecological role of the park, and the behind-the-scenes story of its creation — offering a hopeful glimpse of architecture that can work with, rather than against, the planet.
