Substance Architecture
Part of the Principal Riverwalk, a redevelopment project of bridges, outposts, and plazas that connects 300 miles of trails along the Des Moines River, the Hub Spot contains a café, restrooms, and service spaces within a 2,200-square-foot zinc-and-glass pavilion. The pavilion’s projecting roof shelters part of the Spot’s paver-covered plaza, and undercanopy LED lighting illuminates the area after sunset. Geothermal heating and cooling contribute to the structure’s sustainable ethos. Juror Josh Shelton appreciated the fact that “the trail and the walk passed right through the building. The way that you could get from point A to point B was very lightly interrupted by this structure.” And to juror Gregory Hoss, the pavilion proved to be “an incredibly welcoming and extraordinarily friendly public gesture, but it’s done in a very sophisticated palette of materials, and very simply.”
