Courtyard

A community simulation, open to everyone

Small places.
Big possibilities.

What happens when a world has ideas of its own? Generate a community, build alongside its residents, and explore three possible futures.

Free to play. Open source. Yours to experiment with.

A generated in-game community with editable room interiors and shared utilities, shown after one simulated month.

A small world with real tradeoffs

One beginning.
Three possible futures.

These scenes began with the same homes, people and weather. After one simulated month, different freedoms leave different marks. Switch between futures to find out who benefits and what it costs.

01 / ONE MONTH LATERGuide every change. A scene rendered by the Courtyard Block game.

Guide every change.

Neighbours notice problems and suggest ideas. You decide which projects to approve.

02 / ONE MONTH LATERBuild together. A scene rendered by the Courtyard Block game.

Build together.

Give neighbours a small project budget. The co-op can improve services while you shape the homes.

03 / ONE MONTH LATERLet it grow. A scene rendered by the Courtyard Block game.

Let it grow.

Delegate more freedom. Watch residents add rooms and improve their surroundings, then inspect the tradeoffs.

A loop for curious minds

Try something.
Learn something.
Try something else.

No perfect score to chase. Notice a problem, make a change, and discover the next question.

01

Make a change

Find a seed you like. Snap on a room, move a home, or improve a shared service.

02

Meet the unexpected

Advance a week. Read neighbours’ proposals and watch their permitted projects take shape.

03

Follow the people

Look beyond averages. Find out who is cold, who can pay their bills, and where services struggle.

04

Share a possibility

Keep your inputs and assumptions together. Send a complete experiment to a friend to remix.

The best idea might be yours

Make a world
worth sharing.

Remix construction costs, resident priorities and project budgets in the living-world workshop. Import new wall materials, share your seed and decisions, or draft a kit with your favourite AI assistant.

The same model runs every supported assembly. AI can help draft a pack; you decide which assumptions to test.

A foundation we can build on

Open code. Open questions.

This is an early, bounded simulation. Today: generated communities, resident construction, heat, utilities, costs and one year of fixed households. The inputs are illustrative. More construction methods, richer community life and longer horizons are questions for the road ahead.
