In 2007, controversy began over the last remaining "underdeveloped" parcel of land, known as Square 37. Bordered by 23rd Street, 24th Street, L Street, and an alleyway, this is unusual because its short buildings from the 1800s to the 1960s, are different from the many new, tall buildings on the neighboring blocks. Square 37 was home to the Tiverton, the last remaining rent-controlled apartment building in the West End. The Tiverton tenants gained local media attention for successfully stopping people who wanted to build new buildings on Square 37.
