Open-plan apartment

Step into a 12 by 8 metre open-plan home built from the Cozy Home Interiors pack: living room with sofa, rug, TV and fireplace wall, a dining table for four, and a kitchen with cabinets, sink, fridge and an island with stools.

About

One open-plan room from 24 of the pack's 129 models, on the pack's own 2 m wood floor tiles with ceiling decks above, in the room preset with warm light and lamps under the ceiling.

You come in by the front door module. The west end is the living room: a three-seat sofa on the rug facing the TV on its unit, a coffee table, an armchair, the fireplace wall with a floor lamp and a bookcase. The middle is a dining table with four chairs. The east end is the kitchen: four base cabinets, the sink unit and the fridge along the back wall, the island with two bar stools, and the 3 m bay window in the end wall. The front wall has the patio slider and a window beside the door.

Nothing moves: this pack ships without animation clips. Doors and windows are closed modules; the rest of the pack, from bedrooms to bathrooms, is not placed here since one demo may hold at most 24 distinct models.

Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.

Common questions

How do I use Open-plan apartment with my AI development tools?
Press "Copy for AI agent" above and paste the prompt into Claude Code, Cursor, Codex, GitHub Copilot, ChatGPT or any other coding assistant. The prompt carries the direct CDN URL, the real-world size, the licence and the loading notes, so the assistant can fetch the scene and place it in your project without you writing the loader yourself. For a permanent connection, add the 3DAssets.dev MCP server to your tool with one command (for Claude Code: claude mcp add --transport http 3dassets https://3dassets.dev/mcp) and the assistant can then search the whole catalogue, fetch files and read the usage snippets on its own.

How do I get started?
Walk the scene here with the keys or touch to see how the pack fits together. To build it yourself, download the pack with the button, then copy the "Copy for AI agent" prompt: it links the layout JSON, which lists every placement with its position, rotation and CDN URL, so an assistant connected to the MCP server can rebuild the scene in your engine and change it to order.

MCP server setup

Which game engines and tools can I use Open-plan apartment with?
Anything that reads glTF, which today means all of the major ones: three.js and React Three Fiber on the web, Godot 4, Unity, Unreal Engine 5, Blender and the model-viewer web component. Every model in the scene is a self-contained binary glTF (.glb) with textures embedded, so each is one file to import and no plugin, converter or decoder to install first.
How do I import this scene into Unity, Godot, Unreal or Blender?
Unity: install the glTFast package (com.unity.cloud.gltfast) from the Package Manager, drop the .glb into Assets and drag the prefab in, or load it at runtime from the CDN URL. Godot 4: copy the file into the project folder and the editor imports it as a scene you can instantiate. Unreal Engine 5: File > Import with the built-in glTF importer, which converts the axes for you. Blender: File > Import > glTF 2.0. Units are metres with +Y up in the file, and every importer above handles the conversion to its own axes automatically.
Can I use Open-plan apartment in a commercial game, and do I need to credit anyone?
Yes to commercial use and no to credit. Every scene on 3DAssets.dev is released under CC0 1.0 Universal, which places it in the public domain: use it in a paid game, an app, a film or a client project, modify it, redistribute it, and put nothing in the credits. A link back is welcome but it is entirely your choice.

CC0 licence text

Can I load it from the CDN instead of downloading it?
Yes. The pack behind it has a permanent URL on cdn.3dassets.dev that is CORS-enabled and never changes content, so you can pass it straight to GLTFLoader, glTFast or model-viewer in production and cache it as hard as you like. Downloading is only needed for engines that import from disk.
Is the demo itself a file I can download?
No, and it does not need to be. A demo is a layout of the pack's published models composed in your browser from the CDN, so there is no extra file to fetch. Download the pack for the models, and take the layout JSON linked above for the placements: together they are the whole scene, and an AI agent can rebuild it from those two links.
Can I change the scene, or add gameplay to it?
Yes. The layout is plain data in metres, so move, add or remove placements freely in your own engine. Colliders, navigation and gameplay are yours to add: the demo shows what the pack looks like assembled, and your game decides how it plays.
