146 cases
Key takeaways
- 146 cases include DIY / self-build elements.
- Movable planters suit interim land and restore the site easily.
- Building together breeds community and ownership.
What the data shows
Movable planters and containers pair perfectly with interim land: because soil never touches the ground, restoring the site is easy, enabling low-investment models that borrow pre-development land for a short time.
Building things together in workshops is itself community building, giving participants a sense of ownership that keeps them involved. The norm is to start with minimal kit and expand in stages as needed.
