The stretch of Washington, DC’s M Street between 21st Street and Rock Creek Park—otherwise known as the West End—boasts enough highbrow hotels and restaurants that the neighborhood seems a perfect fit for a squash club. What’s surprising is that the club, as the middle part of a three-tiered cake designed by Mexico City-based TEN Arquitectos, is layered between a fire station and six floors of affordable housing. The project, called West End Square 50 in reference to its lot’s appellation within the planning department, replaces an aging two-story fire station with a brand-new one. But it also injects palpable activity into an inward-facing neighborhood as part of a public-private partnership between the city and developer Eastbanc while making the most of a previously underutilized site. Eastbanc won the bid to redevelop this lot and nearby Square 37 in large part due to its solution for the replacement of municipal facilities and inclusion of affordable housing.
