Floor plans, 3D modeling, room design, kitchen planner, gardens, interiors, AI rendering, walkthroughs — all in a single browser-based app.
Drag walls, drop doors, place windows. The fastest way to block out a layout — and the only one where your floor plan and 3D model are the same file.
Walls become rooms, rooms become floors, floors become a complete 3D house design. Add roofs, balconies, staircases and decks with parametric components.
A room designer that renders in real time. Pick a room type, drop in furniture from our library of 10,000+ models, swap materials, change lighting.
Pre-built cabinet runs, ovens, sinks, splashbacks and worktops snap together to build a kitchen layout in minutes. Adjust unit dimensions on the fly.
Plant trees, lay paths, build walls, add water features and design decks. Arcadium handles terrain, gradients and seasonal vegetation rendering.
Take any view from your 3D model and turn it into a photorealistic interior with one click. Try multiple styles — modern, Scandinavian, Japandi, watercolor — for the same room.
Stairs, windows, doors, railings and roofs adjust dynamically. Change a floor height — every staircase recalculates. Change a wall length — windows space themselves correctly.
Share a URL. That's it. Your client opens it in their browser and joins the same 3D model. No accounts to provision, no files to email, no version conflicts.
Generate 3D models of your furniture to use in your design. Simply upload photos of your furniture and get a model in seconds.
10,000+ furniture models built specifically for Arcadium — performance-optimised, dimensionally accurate. 500+ materials covering wood, stone, fabric, metal, paint.
Walk through your design like a video game. WASD to move, mouse to look. Show clients exactly what the space will feel like at human scale.
Numerical inputs, alignment guides and dimensional constraints. Architect-grade precision wrapped in a UI a homeowner can use.
Arcadium is the modern alternative to Revit, AutoCAD and SketchUp. It's agile, browser based and collaborative: nothing to install, no plugin wars, no separate render engines. Open a browser, share a URL, and your client can walk through the design with you in real time. They can even create designs themselves. See how Arcadium compares below.
