Self-build & co-build
Households and groups building with support rather than being built for.

Focus — Housing, Materials & the Built Environment — Community-led housing
World Seed Fund supports people whose ideas improve how housing is built and held for the households who will live in the homes.
Why this area
Housing works when the people who will live in it shape it. Ideas qualify when tenure, cost, and construction capability are addressed together, not one at a time.
Scope of the area
Illustrations of scope, not a fixed list. If your idea belongs here but is not described below, introduce it anyway.
Households and groups building with support rather than being built for.
Secure occupation, collective ownership, and land access.
Improving existing settlements in place.
What a household can actually pay, and over what period.
Criteria to qualify
All five criteria apply. An idea does not need to be complete or proven — it needs to be specific enough that we can judge it, and grounded enough that a next step is possible.
We need to understand exactly who is affected, where, and how they cope today. General statements about a global challenge are not enough to qualify.
The idea should come from knowledge of the situation — technical, scientific, operational, cultural, or lived — rather than from an assumption about it.
There must be a specific thing that can be attempted next, at a scale that can be observed honestly, with a stated way of judging whether it worked.
The benefit should be meaningful to the community or system the idea serves, and describable in terms they would recognise.
Ideas qualify when someone can plausibly own, operate, fund, and repair the result after the first phase of support ends.
Evidence & boundaries
Evidence can be modest. A careful account of a small trial is worth more than a projection.
Submit an idea
There is no application window and no required format. Answer these four questions in your own words and we will read them.
Who is affected, where, and how do they manage today?
What do you know about how housing is built and held that others working on it may not?
What could you attempt next, and how would you judge whether it worked?
Who continues the work afterwards, and what keeps it running?
Human potential is everywhere. Opportunity should be too.
