Case Study - Attached Deck Pt. 1

The building picked for the Attached Deck typology case study has a particularly interesting story behind the development of its environment as well as the reasons to expand onto the rooftop space. The building is a two-story residential timber structure house built in ~1962-1963. It is a Japanese timber structure with some traditional elements like a pitched tiled roof. It appears, however, that at the time of construction the environment around the building was drastically different.

As was found through the questionnaire and verbal interview with the owner of the house, the big elevated highway which nowadays stretches in front of the house at the level of the house's rooftop did not exist at the time of the house construction. It appeared shortly after the house has been finished, as one of the instances of major infrastructure expansion before the 1964 Tokyo Summer Olympics. This fact can be seen in old maps of the area, which show the difference between the layout of the area—the map of 1944-1954 does not have the highway or any other major roads around the house. Whereas the map of 1965-1968 clearly shows the new elevated highway road and the widened road perpendicular to it which "cuts" through the district that previously had a net of narrow roads and streets that were not even close to the scale of the new elevated road.

As if to further worsen the surrounding situation for the house, it has also unfortunately been facing the wall of an adjacent building. This new tall mansion (multi-story apartment building) was built behind the house in 2011 (suumo.jp 2018). It is an eight-story building which appears to be considerably out of scale in relation to the surrounding buildings inside the same city block (primarily, 2-3 story detached residential houses except for the taller mansion buildings at its corners).
