425 Mass Apartments
Washington, D.C.

If there is one common thread among multi-family owners, it is to provide residents with experiences that are unique and more personal than what they might find down the street. The sister buildings located at 401 and 425 Massachusetts Avenue, NW, which sports the largest roof deck in DC, offered just that opportunity.

Partnering with the HDG interior designers, Equity Residential prioritized the rooftop amenity as Phase One of the planned repositioning of these two multi-family apartment buildings.

The team began with an intense strategy phase that included vetting space usage, points of impact, and budget constraints. The goal was to take advantage of the many meandering intimate nooks and large gathering spaces to create a mixed-use, outdoor haven for the residents.
The existing building structures have a yellow-orange brick fa├žade. To overcome the monotony of the ubiquitous brick that continues at the roof deck, the design team chose wood-look planks, colored wall tiles, murals, and screen elements to clad the brick at focal points. Planting material and green walls add a lush connection to nature.

Many options for work and play, both together and alone, have been planned. The large covered space adjacent to the elevator lobby will be transformed into an open-air bar with lounge seating and gaming for residents to enjoy, rain or shine. In addition to places to work, to play, pools to dip in, and lots of cozy corners to curl up, there are multiple grilling stations and private dining rooms that were designed to allow residents to host private functions.

When finished, the reimagined roof deck will provide a healthy outdoor amenity for residents seeking a respite from the bustle of city life.
