Loft bed platform
A low-poly double loft bed for a small city flat: four oak posts carry a slatted deck with a mattress, mustard duvet, pillows and a folded throw behind guard rails and painted panels, with an oak ladder at the front. Underneath sits a lived-in desk nook with a bookcase, laptop, lamp, wall shelf and stool.

Left rail: colours and the 3 knobs the agent wrote into this model — they rebuild the geometry and go into your download. Right rail: looks for the viewer. Drag to orbit, scroll to zoom.

The brief given to 1DesignTool's “3D object” template:
Loft bed platform for the Cozy Apartment kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. This is one part of the Cozy Apartment kit (Low-poly style, flat-lowpoly direction): A small lived-in city flat. Use ONLY the kit palette, by name: warm white #f9f7f5, oak #8f693d, mustard #c39b22, sage #89a178, warm white dark #ddd2c6, oak dark #594126, warm white light #f9f7f6, oak light #b48f64, soot black #1b1b22, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `wallColour` (0–1, default 0.5) for the kit's "Wall colour" setting wherever it makes sense on this part, and keep that id.

Note: Size: 2.22 m long × 2.00 m deep including the ladder foot (the frame alone is 1.66 m deep) × 2.13 m tall to the post caps, with the origin at the bottom centre on y = 0 and the front (ladder side) facing +Z. It takes a 2.0 × 1.4 m mattress; the deck is at 1.55 m and the guard rail at 2.05 m. The whole build is shifted 0.19 m back so the footprint is centred, so the posts are not symmetric about z = 0. The GLB has 1,784 triangles in 32 meshes (merged per part and palette colour), flat normals, and no animation clip. Every material is named exactly after its kit palette colour (all 11 are used). Params are baked at export, so the GLB is the default build. wallColour steps the rail infill panels (warm white < 0.25 ≤ warm white dark < 0.5 ≤ sage < 0.75 ≤ mustard); the duvet and throw swap between mustard and sage so the bedding never matches the panels. deckHeight moves the deck, rails and ladder; below about 1.5 m the wall shelf over the desk is dropped for head room. bedWidth widens the frame, and below 1.2 m the bed gets one pillow instead of two. Both extremes (1.3 m / 0.9 m and 1.8 m / 1.6 m) were built and passed three-check and glb-lint. plan-check's part-id regex rejects the hyphenated slug ids the library requires, so the plan was validated on a de-hyphenated copy (PASS); three-check accepts the hyphenated ids. glb-lint reports 0 errors. Its warnings are expected for this pipeline: per-part material instances, non-indexed flat-shaded geometry, nested trims overlapping, the mug resting on the desk in another part group, and a scale heuristic tuned for 1 m props.
About the Loft bed platform 3D model
Loft bed platform is a free low-poly 3D model from the Cozy Apartment set. It measures 2.2 m × 2.1 m × 2.0 m (W × H × D) at real-world scale and is built from 1,784 triangles across 32 meshes, with 10 named parts. Download the 152 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
- Is the Loft bed platform 3D model free for commercial use?
- Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.
- What file format is it, and how big is it?
- A single binary glTF 2.0 file (.glb), 152 KB: 1,784 triangles, 5,352 vertices and 32 materials, modelled in metres at 2.2 m × 2.1 m × 2.0 m.
- Can I animate Loft bed platform?
- It ships as a static mesh. Its 10 named parts are separate nodes, so you can move or animate each one in your engine.
- Which engines and tools can open it?
- Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.
- How was the Loft bed platform 3D model made?
- Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.
