Residential cluster
Create a new repetible, integrated and expandible system of clusters
Matrix: system of clusters
Small support core
Settlement formed by the agregation of clusters, integrated with the public space matrix
Semi-private areas, the users are the inhabitans of the neighborhoud (usually groups of 8 families). The function in the area are essential for living. Farming and food storage
Water collection and depuration
House x48
Collect and purificate water locally to use it into the houses and for cultivation.
Residential clusters High density Legal settlement
An area for farming with a small paddok and food storage to provide food. Using a Top-Down Support where governments/ONG provides support spaces and the community manages the productions locally.
Shared oven and kitchenette
Laundry
The shared oven and the kitchenette have a double function: a meeting point for woman and a place to mantain and hand down local traditions.
Shared laundry to decrease the waste of water.
Medium support core Low density
Semi-public areas, the users are the inhabitants of a district (about 48 families). It’s used a Top-Down approach. The function, beyond having an educational purpose, meets market demands so they can became small businesses.
Small support core x6 (1x8 houses)

Contested settlement
Plant nursery as support area for the local farming, with a possible educational function.

1300 tons of waste per day are produced in Gaza. In every medium core there is a recycling point to reuse waste material. Every recycling point is specialized in some type of materials.
Local composting plant
Laboratory and safe area
Currently compost is bought from israeli producers, considering that the 67% of waste are organic material, Gaza can produces it-self compost for agriculture.
Laboratory to learn how to produce goods(building materials, toys etc), also with waste material, and sell in the market.

Some numbers:
In this new district in north Al-nada we use the same system of clusters that characterizes the low-density settlement, but with a vertical development. The linear Bazaar is the main element in the project and represents the public space for the community, connecting all the district. Medium cores are shared among all the population; instead of all the buildings having small cores in the courtyard, these semi-private spaces are designed exclusively for the building’s residents.
