Unity Room — A Spatial Study in ProBuilder

Build a calm, navigable room — entirely from primitives.

I gave myself a one-week constraint: build a 3D space worth being inside, using only Unity's primitive tools and ProBuilder. No imported assets. The point was to study composition and proportion at the level of geometry, not at the level of decoration.

Walls, platforms, cutouts — flow before furniture.

Layout came first. I sketched the negative space — where would someone walk, where would they stop, where would their eye land — then placed walls and platforms to make those moments happen. Every surface was modelled with first-person scale in mind, so movement through the room would feel proportionate, not theatrical. Cutouts and platforms create the rhythm; the room reads like a corridor designed to slow you down.

Baked lighting plus real-time spots — light defines depth.

Materials were intentionally flat — almost no PBR detail, just clean colour. The room's depth comes from light, not from textures. Baked global illumination provides the soft gradients; a small number of real-time spots cast hard shadows on what matters. I also tested colour-temperature shifts to fake different times of day, since the same geometry reads completely differently under warm vs. cool light.
