World Architect is an upcoming free world editor for The Sims 4. Shape the hills, lay the streets, mark out the lots, and move your Sims into a place you planned yourself.
In development. Follow along in the workshop letters.

World Architect is still being built. Here's what we're working on, what works today, and what comes next.
You build in the same order a real town grows: the ground first, then the streets, then the homes.
Raise hills, carve valleys and smooth the slopes, then paint the ground with grass, sand and stone.
Draw roads that follow your hills, join them at junctions, and add rivers and ponds along the way.
Mark out lots, set each one's venue, dress the streets with trees and lamps, and pick the time of day.
