There's no mistaking the 530 House from the road. For neighborhood kids and pizza delivery drivers, the wall-size street number is its defining feature, stenciled strikingly on a white panel in- side the glass foyer. But that's probably its least compelling aspect. Designed by Nathan Kalaher, AIA, and his wife and business partner Lisa Kalaher, AIA, for themselves and their two young sons, the house has gorgeous views of the Missouri River. "It feels like the land is with you as you move through the house," Nathan says. When the couple bought the riv- erfront lot in 2008, it was positively bucolic with a woods and prairie. But an asset can also be a threat, and in 2011, a greater than 500-year flood wiped the slate clean. Luckily the house existed only on paper at that point, but the event forced a redesign when the land was built up as part of a flood control project. The exposed site was now on a levy, and there were no trees to provide privacy. Located in a South Dakota suburb about 5 miles from Sioux City, Iowa, the lot has views of agricultural lands across the Missouri River and an alluvial plain to the south; to the east and west are oth- er homes, and a woods is on the north. Although code allows homeowners to build at the 100-year-flood mark, the couple wasn't taking any chances. They brought in an earthwork crew to raise the lot 8 feet above street elevation on a gradual slope. That puts the house about 20 feet above the river's normal level. It also seemed wise to forgo a base- ment that could fill with water. "That is not typical where we live because of storms," Nathan says. "In some ways the house is detached from the site, sit- ting fully on top as opposed to engaging it, which also poses a potential threat during weather events." That base is covered too, though, with a concrete storm shelter tucked under the master bedroom deck. This page and opposite: 530 House, with its giant address mural showcased in the foyer, is a favorite destination among package delivery professionals. Raised 20 feet above the river, the house is designed to withstand periodic flooding from the Missouri River. 63 VOL. 1, 2019 RESIDENTIALDESIGNMAGA ZINE.COM
