House in Sonobe designed by Tato Architects, located in residential district of Nantan boasts terrace enclosures as sunrooms to adapt local climate.
Wide eaved terrace, semi-outdoor spaces, square grid with diagonals ends as intimate or void spaces in the house act as interface between surrounding environment. Inspired by local architecture, the architects enclosed the ‘sunrooms’ with doors which can open to adjoining space.

From the Architects –
This house stands in a new residential district in the mountains, which was put up for sale in the 1990’s. The region has a slightly cool and wet climate. When looking at other houses in the vicinity; you can see that many of them feature lean-to-sheds, designed as small sunrooms. They are made by enclosing a back entrance or veranda with corrugated polycarbonate panels.

These so-called ‘terrace enclosures’ are often used as storehouses in winter, or as places for drying laundry. It’s a very clever feature, that we realized represents, a certain style shared among the various new mass-produced houses of this residential district.

We used these terrace enclosures as inspiration for the materials and functions of our sunroom. We also incorporated a wide-eaved terrace and other semi-outdoor spaces into the interior of the house. Our expectation was that these would act as interfaces between the surrounding environments.

Volumes within Sonobe house –
Regarding the volume of the house, we used a simple square grid and its diagonals to create the different spaces. One of the space is intimately sized, and another containing a spacious void. To each of these, we attached semi-outdoor spaces. The wall of the sunroom is made from a large hanging door.

It can slide open to turn the sunroom into an outdoor area, or enclose the second floor space under the eaves. On the south side of the site, we followed the example of the neighborhoods lean-to sheds and created an alcove and storage space.

Around the house, centered on the site, we piled up the earth left over from the foundation work in an attempt to reclaim the original slope that existed before the site was developed into tiered platforms for residential development. This reclaimed mound of earth will be covered in grass, and with time, the owners will make it into a garden.
