What We’re Following

Iowa raucous: Schemes to increase density and bring housing costs down by loosening restrictions on building multi-family housing—a planning gambit known as upzoning—have been sprouting up in many U.S. cities. In the past few months, ambitious upzoning laws have been approved in Minneapolis, Austin, and Seattle. Given that trend, it might look like downzoning (changing codes to encourage single-family homes and sprawlier development) is on its way out. If that’s true, Des Moines never got the memo.

The Iowa capital’s proposed zoning plan would do the opposite of upzoning. The rules approved last night by the city’s zoning commission set a high bar for building appearance and minimum requirements for construction. The plan includes strict preservationist standards—not for historic homes, but for new construction. New Des Moines homes are required to have garages, basements, and generous yards; lower-cost building materials like vinyl siding are discouraged. The city says the new zoning rules will save money by simplifying permitting, but local home builders warn that the raft of restrictions will make buying a new home harder for residents. “Anybody making under $90,000 annual income will not be able to afford these homes,” one tells CityLab’s Kriston Capps.

What can the history of temple design tell us about the history of London’s Hindu community? Today, over half of the United Kingdom’s more than 800,000 Hindus live in London. “Walking or taking the bus around my neighborhood,” Erica Eisen writes, “it’s not uncommon to come upon a temple unexpectedly. They range from plain brick buildings to lofty-towered structures in traditional Indian architectural idioms.” The history of these temples, she writes, reflects the generational history of Hindus in the U.K. On CityLab: How Temple Facades Tell the Story of Hindus in London
