This time we present you a converted Japanese design house in Ōta, which is located in an alley next to a shopping street in Minimiyukigaya. It is also bordered by another street to the east and a three-story and one-story apartment block to the south. The building contains two independent residences – one for a mother and the other for her son and his family. These were designed with the intention of eventually converting them into rental units.
A Japanese design house for the whole family
The grandmother occupies the first floor while her son, his wife and their child are on the second and third floors. On the third floor there are private areas such as a living room and a children’s room, as well as the bathroom. The architect designed the rooms there as a single total volume.
The first floor has also been treated as a single volume to create space for a terrace on the roof of the first floor. Between these two volumes, two continuous areas delimit the second floor. These interlock like pieces of a puzzle and encompass an open living room that is integrated into the balcony.
Japanese design house with innovative interior design
In order to bring as much light as possible to the first floor, the team inclined the roofing of the floor on the south side steeply upwards. For this reason, the architect provided the roof with a skylight on the raised edge. On the second floor, this slope becomes a sloping wall that extends the floor of the roof terrace upwards. In this way, it works as a privacy screen by blocking the view from the hallway of the adjacent residential building.
The trees planted along the raised roof edge are typical elements of a Japanese design house. These shield the building from the third floor of the residential building and bring in speckled light. Thus, the residents can enjoy the changing light and green patterns.
Minimalist designed interiors
Designing residential architecture in densely built-up areas can really showcase an architect’s skills. In this regard, a Japanese design house must address both the environment and the individual needs of the local people.
In this case, the designers used an unusual three-dimensional shape to respond to the contradicting requirements of compliance with building codes in terms of building height and light and / or view obstruction. Furthermore, privacy and the distance from surrounding buildings had to be taken into account. In addition, effective light should be guaranteed in the living spaces.
