The following residence is located in Nagahama, Shiga, on a corner plot within an area with many plots for sale. It’s surrounded by other houses that were built around the same time, and this site is near the entrance of the subdivision. The client was willing to live inside an open, bright house with an extraordinary feeling. ALTS Design office designed the interior and the exterior elements.

As the house stands on a corner plot near the entrance to the subdivision, the designers proposed an exterior of the house that stood boldly open with white and gray to give the extraordinary feeling that the client was looking for. To have an impressive building design, the mind shifts naturally from ordinary to extraordinary. To protect the client’s privacy from the surrounding area, the design included built a courtyard.


On the interior of the house, the living space is open to the south. The space is bright and open towards the outside and the private space is located on the back of the house.

The ceiling also gets higher as it gets closer to the windows, creating an even more spacious feeling in the living area. By dividing open space and private space, it creates a relaxing, extraordinary feeling. The interior space has a muted, monotone gray color, and tiles and ceramic materials add a calm feeling to the space.


A space is created to accommodate the busyness of everyday life, and there is a space that carries the ordinary feeling of everyday life and relaxation that you might feel during a vacation. In times when it’s hard to go out freely, having a space like this adds richness to everyday life in the house.
