Japan’s traditional residential architecture is recognized for its regional variety, but research has primarily focused on main houses, with annex houses, huts, and cabins receiving less attention. However, these structures often played an essential role in supporting local livelihoods and shaping the cultural landscape. This study examines historical masons’ work huts in the northern part of Otsu city, Shiga Prefecture—a region renowned as a fine granite quarry site, where high-quality stone products such as lanterns and shrine gates were produced. Since no work huts remain in Kitahira, but in Minamikomatsu, interviews with current and former masons were conducted to understand their structures and construction processes. A measurement survey was also conducted on one existing work hut in Minamikomatsu. The work huts in Kitahira and Minamikomatsu exhibit varying levels of construction sophistication in foundations, wooden structures, roofing, and walls. Although both were gable-roofed, the former, a self-built post-in-ground structure with a thatched roof, contrasts with the latter—a post-and-beam hut with sophisticated joinery, crafted by skilled carpenters. These differences are linked to the locations of the huts and types of stone products produced. The construction methods represent the intelligence of residents in making efficient use of available materials and resources to sustain their livelihoods. Today, with the decline of the stone industry and an aging population, memories of this vernacular architecture are fading. Documenting the stone masons’ work and their work huts is crucial for safeguarding the cultural identity of the region and enriching our understanding of its history.
