台陽礦業事務所, Historic building in New Taipei, Taiwan.

The Taiyang Mining Company Office is a single-story reinforced concrete building completed in 1937 near the Bafan Pit in Jiufen. Its eclectic style shows pilasters faced with thirteen-groove tiles and washed-granite railings, with a rain canopy and cornice line; vents in the ceiling and walls respond to the damp mountain climate. A large courtyard in front looks out over the Jiufen coast.

Built in 1937, the office served as the administrative center for major mining operations across Taiwan. The building emerged during a period when industrial development was rapidly transforming the island's economy.

Locals call the building "Huishe" (the company), a name that stuck from its years as the Jiufen mining office. Beside it stands the 1902 road-repair stele, cut from andesite, honouring Yan Yunian and Su Yuanquan for building the Baojia road between Ruifang and Jiufen. The nearby Peng Garden, once the company's second club, held martial-arts facilities and later trained mine technicians.

The office is a working staff building and is not open to visitors, so it can only be seen from outside. It stands beside the Bafan Pit in Jiufen, with a large garden around it that looks out over the Jiufen bay. A road-repair stele of 1902 stands on the grass to its right.

The interior holds ore specimens, a gold-refining flowchart, some mining tools and an oversized balance scale, kept while the building still serves as staff offices. Visitors cannot enter, but the large garden around the building looks out over the Jiufen bay.
