It was a gas and car repair station designed by Continental Oil Co. architects as an "English cottage-type station". The design included a steeply pitched gable roof with dark green asphalt shingles, contrasting to the off-white glazed brick exterior. It was built in 1936 and expanded in the same style, to add a second service bay, in 1941. A 29 by 35 feet (8.8 m × 10.7 m) flat roof expansion which does not match was added in 1975 when Joe Kincaid took over operation. Twenty-eight years later in 1993, Kincaid still operated the station.[2]

It was deemed significant as "one of finest examples of 1930s era gas station design in Montana" and as "the best original domestic, English cottage design remaining in the State. The styling reflected the desire to avoid conflict with nearby residential environments and blend effectively with adjacent commercial structures. The beautifully maintained glazed brick exterior is accentuated with natural brick trim around windows and doors in the classic 1930s style. The high-pitched gable roof and distinctive white and green color scheme made the station a familiar and recognizable landmark."[2]
