Ridge Street Row is located on a quiet, tree-lined street in the heart of the up-and-coming downtown Washington, DC Shaw neighborhood. Eight spacious, comfortable, and environmentally-friendly residences are gracefully and efficiently designed within four adjacent townhouses. The two-story brick facade with punched windows and the recessed third-story, sloped glass wall is compatible with the scale of the surrounding historic two-story row houses and act as a dialogue between modern and historic.

The design of Ridge Street Row incorporates four key features: an environmentally efficient structural system, maximum light exposure, maximum cross ventilation and large private outdoor spaces.

Using a sustainable structural system rather than traditional wood-frame construction, the row houses are built of prefabricated concrete panels and hollowcore concrete planks. Concrete construction offers durability, non-combustibility, sound absorption and cost-efficiency, making it ideally suited for high-density urban living. The structure was rapidly erected on-site, thus reducing construction duration. Material waste is kept to a minimum.

The units are configured to have open living spaces with large expanses of glass that extend the rooms beyond their walls. North-South orientation, with operable windows at either end, encourages natural cross ventilation throughout the spaces. Large expanses of high-performing, low-e insulated glass minimize the need for artificial light and create airy and comfortable interiors while not over-burdening the mechanical system. The rooftop terrace slab is insulated with solid pavers that help the roof retain heat in the winter and cool air in the summer.

The enclosed patios at the lower level flats provide a peaceful urban oasis for busy city dwellers. The private roof terraces with magnificent views of the monuments both elevate and blur the boundaries between the cityscape and shelter.

Ridge Street Row seeks to set a standard for urban living by achieving not only ecological but aesthetic harmony between a structure and its historical surroundings.
