What could the ideal home in this region be? My working answer is the Hosh: a courtyard building of six to eight storeys for twenty to thirty households, where sun, water, food, heat, materials, and information circulate through the architecture. Private homes stay private. Expensive tools are shared. The structure is meant to last a century while everything inside it can change.

It comes in three versions, tuned to Jerusalem’s hills, Haifa’s sea air, and Hebron’s highland courtyards. Below is a model you can take apart system by system, and twenty-five plates that go through it piece by piece. It is a concept design, not to scale, and every number on it is illustrative.
