Arcadium is a 3D house design tool that runs in the browser. It lets users draw floor plans, build complete 3D house models, lay out kitchens, plan gardens and visualize interiors with AI, all in one app with no download required.
The site describes it as modern 3D modeling software for architects, interior designers and homeowners. It lists support for Mac, PC, iPad and mobile, and cites more than 250,000 designers and homeowners among its users.
Its main pitch is speed and ease compared with traditional 3D software, which the company says demands technical skill and training. Customer quotes on the site repeat this point, with one user saying they moved to Arcadium from SketchUp.
Users start by drawing walls and adding doors and windows. Walls become rooms, rooms become floors, and floors become a complete 3D house. Furniture, plants and cabinets come from a built-in model library, and parametric objects such as stairs, doors and windows follow standard sizes.
The same design can be viewed as a top-down floor plan, from multiple perspectives, or as a first-person walkthrough. Users can adjust lighting, materials and colors, add labels and dimensions, and change units.
For AI visualizations, a user picks any view of the 3D model and generates an image in a chosen style. Designs are shared by URL, and users can create cross sections and elevations for builders and planning regulators.
The core modeling tools include a floor plan creator, parametric components for roofs, balconies, staircases and decks, alignment tools, grouping, locking and precise measurements. The site cites a library of more than 10,000 models.
Specialist tools cover kitchens, with cabinet runs, ovens, sinks and worktops that snap together, and landscapes, with trees, paths, water features, decks and terrain. A free color palette generator creates palettes from an uploaded image.
AI features include styled interior visualizations from any 3D view, ranging from photorealistic to Scandinavian, Japandi, sketch and watercolor looks. A separate option lets users design with ChatGPT, Claude or Gemini and then edit the result in Arcadium.
