The specifications for 400 K Street conform closely with those of 300 K Street. The building will have 11’6″ ceiling heights slab to slab with floor to ceiling glass.

A notable difference is that the building is dual core and can be built in two phases of approximately 210,839 rentable SF each. Separate lobby entrances and service facilities will exist for each section. Spanning the entire project, approximately 23,165 rentable SF ground floor will be available for retail space.
