House OS is a modern two-family house located in Aichi, Japan, designed in 2018 by 1-1 Architects.

Description
It is a plan for a two-family house for the owner who runs a tropical plant farm with the whole family. In the countryside of Japan, legal farmland and residential land are adjacent to each other and are mixed. The owner of this project also purchased a site consisting of three types of land: “residential land”, ” farmland (with a road)” and ” farmland (without a road)”. At first glance, these lands seem to be one, but there is a strong invisible borderline between neighboring lands as stipulated by law. By focusing on the borderline of the neighboring land, we propose a new landscape of rural farmland and residential land.

On the other hand, to show that the land of each building is different, we designed a very narrow gap between the three buildings. In the gap, a new borderline of the adjacent land is drawn due to the environment such as light streaks, raindrops, and wind escape. In this plan...
