DC Design Center Update After the sale of its D Street, SW, building was announced last year, The Washington Design Center had an uncertain future. But following a long search, it has found a new home in the Franklin Court building at 14th and L Streets, NW. According to Ann Lambeth of J. Lambeth & Co., a member of the steering committee representing the Center’s luxury home-furnishings showrooms, the majority of current tenants has committed to the move. The Design Center will occupy the second, third and fourth floors of the building, which boasts 11-foot ceilings and abundant natural light.
