Tinyrise / Your collection

Your studies

No timer. No money. Each brief is optional, and starting one is undoable.

The garden next door

Connect the west roof to the east garden, keep the courtyard open, and bring three visitors upstairs.

Lunch between the wings

Give this connected complex a café people can reach. Keep the studio and workshop in use.

The old foundry

Preserve the east brick hall. Add an accessible roof garden and keep deliveries flowing.

Interior movement is abstracted. Connected same-floor cells are one interior; only marked entrances and stair cores connect them to the outside and other floors.

Three proposals. Preview the changes without touching your study, then keep one. Activity anchors, entrances, cores and your selected floor are protected.

Amber = added volume. Red = removed volume. Your original is unchanged until you keep a proposal.

Keep a named study with its uses and connections. Stored in this browser; JSON is the portable backup.
Quick reference

Controls

Neighbourhood: choose occupants, mark indoor bays on the floor plan, and fit out the space. The existing shell is free; fit-outs, amenities, and expansion use refundable credits. Earn community grants and host busy days when ready. The old presets remain unrestricted free build.

Click a roof to add a storey, or a wall to extend sideways. Neighbouring cells share façades. Roofs, glass, parapets and industrial details follow the shape. There is no economy or gravity simulation. The Living Edition adds destination-driven people, explicit access links and optional commissions. Use the Live tab for roof/plaza activities and Connect for entrances, stair cores and skybridges.

Lift adds one storey to the connected, flat roof you click. It preserves each cell's material. A 2 × 2 or 3 × 3 brush works in the plane of the selected face. Erasing does not automatically delete the blocks above.

Interior movement uses an abstract floor-and-stair graph. Free camera has no collision or gravity. Browser saving is best effort; JSON is your portable backup.

Inspiration, not affiliation
The starting sparkMiniopolis

Luke Schneider / Radiangames

Modern block-by-block buildings and the public demonstrations of neighbour-aware procedural architecture.

The interaction foundationTownscaper

Oskar Stålberg

A playful block-to-architecture language, where small edits become coherent places.

Design referenceTiny Glade

Pounce Light

Adaptive architectural details and the pleasure of making something without pressure.

Design referenceDystopika

Voids Within

Atmosphere, miniature city-making, and photography as a reason to linger.

An independent experiment. These creators inspired the direction; they are not collaborators or endorsers. No code, meshes, textures, or sound assets from their games are included here.

Development & technology

AI-assisted development under Trent Sterling’s direction, with iterative playtesting and visual review. Building meshes, inhabitants, sounds, and shaders are generated in this project.

The default renderer is embedded WebGL2. No installation, account, or remote assets are needed to play. The optional ?backend=three adapter loads Three.js r180 from a CDN; that path is not part of the validated offline build. Three.js / authors / MIT license.

Neighbour rules build the architecture; this is not a reconstruction of the reference games’ private algorithms. Public reading: Miniopolis public breakdown · Oskar Stålberg’s tile-based towns talk · Maxim Gumin’s WFC reference. WFC was background reading, not a runtime dependency.

Save files use the tinyrise-building and tinyrise-city format IDs. JSON and GLB identify the software creator; they do not assign authorship of your building to someone else.

About · More by Tront

Tinyrise by Tront

Tinyrise is a free browser city builder in the spirit of Townscaper. Place concrete, glass and brick blocks, bridges and cafes, and the city grows real routes between them: stairs that connect, streets that go somewhere. Then zoom all the way in and watch one tiny resident actually use the stairs you built.

It renders in WebGL2 from a single HTML file with no install and no assets to download, and it was verified with a headless browser harness that checks every build from placement to pathing. Made by Tront (Trent Sterling) with AI coding tools, as one of a run of small browser worlds shipped in public.
