Completion

This new 10-story state office high-rise at the corner of 10th & O Streets in Sacramento, fulfills critical office space infrastructure needs for the State of California. It will serve as a temporary home for the legislative and executive elected officials for the duration of the Capitol Annex renovation. Afterwards, the building will remain the home for the legislative and executive staff.

Our Progressive Design-Build team of HOK and Hensel Phelps achieved the State’s aggressive energy use goals of Zero Net Energy and Carbon Neutrality through innovative design solutions which use a fraction of the energy of conventional office space. An energy efficient building skin allows for high levels of daylighting, minimizing direct sun on exterior glazing. Additionally, the split-core concept allows for an open plan with naturally-lit waiting areas, and several clustered conference spaces and common great rooms with views of the State Capitol. A highly-transparent open stair connects great rooms, encouraging impromptu meetings and interactions. The latest technology in lobby spaces and hearing rooms on the first two floors allows constituents to participate in government both inside hearing rooms and while in queue. Amenities include spaces for caucus meetings, conference committee meetings, general meeting rooms, legislative and executive branch offices, and integrated parking. With unparalleled views of Sacramento, the building will house 1,250 staff at opening and up to 2,200 staff in the future. A ground floor café will be open to the public after the Capitol Annex renovation is complete.

The project is designed to achieve a LEED Gold certification.
