Cisterra developed a new world class corporate headquarters for Sempra Energy. The design of the project was greatly influenced by the historical buildings on site and the desire to maximize views into Petco Park and the surrounding downtown areas along with panoramic water views. Floor-to-ceiling glass walls, looking out to beautifully landscaped plazas, containing a “green” plant living wall, and a serene water feature activate the building’s expansive lobby.


The lobby and entire base of the tower was designed with large expanses of glass to create transparency and porosity so the lobby and the public right-of-way are seamlessly connected. The building's location offers its tenants the best in entertainment, dining, and amenities that San Diego has to offer.
