10th & O Street Capitol Annex Swing Space

The Swing Space Annex temporarily houses approximately 1,250 legislative and executive elected officials and staff from the Capitol Annex until the new Annex project is completed. The building will then be jointly used as office space for legislative and executive employees. The 10-story building is approximately 472,600 gross square feet and includes function space for committee hearings, caucus meetings, general meeting rooms, and legislative and Executive Branch offices, as well as parking. The project was designed to be one of the most sustainable state office buildings to house elected officials in the country, with the goal of LEED Gold, and having achieved LEED Platinum. To meet that certification level, the building features low water use fixtures, a high-performance building facade, materials with high recycled content, day lighting, native vegetation on the surrounding site and terraces, as well as LED lighting throughout. Upon completion, the 10th & O Street building will be Zero Net Carbon and will also achieve Zero Net Energy through energy efficiency and offsite power generation.
