house's restored timber structure forms around traditional hiroma gathering space in japan

NYAWA Transforms Rural House in Toyama into a Versatile Retreat

NYAWA takes over a thoughtful renovation of House in Toyama, located in a rural city in Hokuriku, Japan. The project transforms an initially unused house into both a vacation home and a rental space. The renovation process prioritizes the preservation of the existing structure, focusing on minimal energy use and integration with the local climate and culture.

The design draws from traditional Hokuriku houses, specifically incorporating the concept of ‘Hiroma,’ a gathering space that historically served as an indoor area to experience nature during the winter. This design choice aligns with the region’s architectural tradition. The ‘Hiroma’ is strategically positioned in the center of the house, functioning as an open space surrounded by the structure and thermal compartments. This setup allows for daylight penetration and a connection to the surrounding environment. The varied floor levels within the central space create an enclosed landscape, offering multiple small resting spots.

renovation establishes a Connection of History and Environment

The design further emphasizes creating a connection between time and environment, promoting a sense of history and continuity. The design team at NYAWA achieves this through adhering to traditional house scale rules, upcycling old timber, and incorporating materials that evolve over time, such as plywood, copper, and silk textile. The renovation plan also addresses the indoor environment, ensuring ample daylight and natural ventilation. Sliding doors are strategically installed, providing occupants with the choice to balance natural and controlled environments. This approach blurs the boundary between the natural and artificial, resulting in a comfortable and contemporary living space.
