WASHINGTON — D.C. based Urban Investment Partners, which has made dozens of apartment conversions in the Washington area, adds the former headquarters of National Public Radio affiliate WAMU to its residential portfolio.

The renovated building is called, appropriately enough, Frequency Apartments, a nod to its broadcasting past and is now a 100-unit luxury apartment building.

Frequency is at 4000 Brandywine St., NW, the home of WAMU for nearly two decades before the radio station moved to its new Van Ness headquarters at 4401 Connecticut Ave. in 2013.

UIP bought the building, along with two other properties, from American University in 2016 and undertook a yearlong, $14 million, 36,000-square-foot gut renovation of the building.

The redevelopment also included a 14,000-square-foot addition to the building.

Frequency Apartments is about one block from the Tenleytown-American University Metro station.

UIP calls the building its most contemporary apartment community to date.

It includes a roof deck, fitness center, resident lounge, conference and meeting rooms and reserved garage parking.

One- and two-bedroom apartments range from about $1,820 a month to $3,300 a month.

UIP owns and manages more than 2,800 apartments in D.C. and Maryland and has renovated, restored and built more than 25 downtown apartment buildings and condos over the last 10 years.
