Helios House
The Helios House is a gas station in Los Angeles, California, United States, located on Olympic Boulevard. It is designed as a green station with special features and is considered to be the "station of the future." It is the first gas station in the world ever to be submitted for LEED certification. The gas station was designed by Office dA (Principal architects Monica Ponce de Leon and Nader Tehrani) in Boston and Johnston Marklee Architects in Los Angeles. The architects were hired by Ogilvy & Mather, led by Brian Collins. The lead on this project was Ann Hand , and the purpose of the design was to reinvent the gas stations. The station's roof is designed of triangles made from recycled stainless steel and contains cacti and 90 solar panels. This reduces the energy consumption of the station by 16%. The station's roof is drought tolerant and collects water for irrigation. The station replaced a run-down Thrifty gas station that previously occupied the site. Built in 2007, it is seen as a Los Angeles landmark. It started out selling BP branded gasoline (at the time, the only BP branded station in the West Coast), but in  2009 switched to its more prominent West Coast sister brand (at the time) ARCO. As of 2021, it is a Speedway Express, a gas station-only brand of the Speedway chain, which, in turn, was a former subsidiary of Marathon Petroleum, ARCO's current parent company, and now a subsidiary of Seven & I Holdings, parent company of 7-Eleven.
