We designed a house on a hill overlooking Lake Biwa. The owner who is a dog lover required to enjoy living with his pets. We chose a one-story building with a courtyard so that he could stay outdoors while preserving privacy from the surrounding houses. The courtyard overlooking Lake Biwa has become a cozy, warm and luxurious outdoor space with an indoor atmosphere. The interior of one room is somewhat divided by bending around the courtyard, creating a slightly different space. We would be happy if a favorite place is chosen according to the season and time, creating a generous and comfortable living atmosphere like drinking coffee at a table overlooking Lake Biwa in the morning and taking a nap on a large sofa near the courtyard in the afternoon.
