Life in Tokyo - Retrospective future of back-to-urban-core houses

What was so-called "ji-ah-ge" in Japan -- isLand aggregation during the economic growth period was a mechanism whereby the floor area ratio was raised and the value of the land was raised, mainly due to better road conditions. If there is a land facing a wide road and a piece of land behind it leads to a narrow branch, the piece of land is restricted to a very low height and volume by the narrow front road width; but these are Integrating with the road-facing land gives a volume far greater than the sum of the largest volumes so far.

The LIT site is exactly the opposite. Originally a site where a medium-sized building was built, it is one of three divisions. Only one of the three sections is approaching the old front road, and the other two are on the side branch road (private road, deemed road). The LIT site is, of course, in the middle, low in height and volume. The land for a middle-rise building is divided without being sold as it is, its value has been reduced and it can be purchased for a detached house.

This is a different phenomenon from the division of a large mansion by inheritance, as in Setagaya. It may be a symbolic phenomenon of the "early period" of the shrinking and depopulating era. In other words, the floor (volume) is already surplus, and even if it is not sold, it will be sold even if it is reduced in value (division). As land becomes smaller and prices drop, smaller residential-scale buildings are newly built in the city center and become less dense.

Detached downtown area. Knowing that there are only small buildings that can be called small, the client has hoped to have offices and rentable floors from the very beginning. These demands may clearly indicate the potential of urban detached houses in the shrinking and declining population era. To abandon the architectural theme of pursuing the psychological size of a small house, squeeze a family of four, shop children, office people and their belongings, and counter the low density. Perhaps you are returning to the vertical version of the former rowhouse.
