A wine storage facility surrounded by picturesque mountains and breathtaking scenery nestled at the foot of Mt. Komayumi in Aoki Village, Nagano Prefecture.

Considering the soil's suitability for winemaking at this site, the idea emerged to utilize it as the finishing material for the exterior walls. This approach resulted in a building that is seamlessly connected to the land.

Additionally, by embedding half of the building into the ground, heat insulation and thermal performance were enhanced, resulting in a temperature and humidity-controlled environment ideal for wine storage.

The chilled storage space consists of solid concrete walls devoid of windows, effectively minimizing heat transfer. An emblem inspired by the rising sun over Mt. Komayumi is located within the hammered finished alcove at the end of the space. The textured concrete surface, bathed in a beam of light, captures the essence of passing time and the seasonal ambiance within the interior.

Our aim was to create a building that reflects the terroir of the region. This was achieved by minimizing artificial elements and instead utilizing the land itself as a primary material in the creation of the space.
