Arcadium: AI-Powered 3D House Design for Floor Plans & Interiors

Introducing Arcadium: Where AI Meets Architecture

Arcadium redefines home design with intelligent, browser-based 3D creation. It’s not just another floor plan generator — it’s an end-to-end AI architecture assistant that transforms rough sketches or room dimensions into photorealistic, navigable 3D spaces in minutes. Whether you're visualizing a dream kitchen, planning a full-home renovation, or presenting spatial concepts to clients, Arcadium delivers precision modeling, smart styling, and real-time collaboration — all without downloads, subscriptions, or design expertise.

Getting Started with Arcadium — In Under 60 Seconds

Launch Arcadium in any modern browser, sign up (it’s free), and begin designing immediately. Start by sketching walls with intuitive click-and-drag controls — doors and windows auto-insert and align perfectly. Then, bring your space to life: apply wall finishes, flooring textures, and lighting schemes with one click. Populate rooms using Arcadium’s curated library of scale-accurate 3D furniture — rotate, resize, and reposition items with pixel-perfect control. Switch seamlessly between top-down blueprints, interactive 3D walkthroughs, isometric previews, and immersive first-person mode. Adjust ambient light, add spotlights, and fine-tune color temperature to test how natural and artificial light interact. Every element — from staircases to sliding glass doors — is parametric: change one dimension, and the entire system updates intelligently. Export measurements, annotate layouts, and share live, editable links instantly.

FAQ from Arcadium

What is Arcadium?

Arcadium is a next-generation AI architecture platform that merges generative design with precision 3D modeling. It empowers homeowners, designers, contractors, and educators to draft, visualize, iterate, and share residential and commercial spaces — all within a secure, cloud-native interface. No plugins. No learning curve. Just intelligent, instant spatial creation.

How do I get started with Arcadium?

Sign up → choose a template or start blank → draw walls (with automatic corner detection) → insert doors/windows → style surfaces → drop furniture → adjust lighting → switch views → share. That’s it. Most users complete their first polished floor plan in under 10 minutes — even on mobile.

What’s the best free floor plan creator for beginners?

Arcadium stands out because it combines zero-cost access with professional-grade output. Unlike legacy tools requiring installation or complex licensing, Arcadium runs entirely in-browser and uses AI to simplify decisions — like suggesting optimal furniture arrangements or auto-generating compliant stair configurations. It’s trusted by over 120,000 DIY renovators and interior stylists worldwide.

Do I need an architect to draw house plans?

For conceptual exploration, layout testing, or visual communication — absolutely not. Arcadium helps you validate spatial ideas before investing in formal architectural services. For final construction documents, local code review, or engineering sign-off, licensed professionals remain essential. But Arcadium dramatically reduces revisions, miscommunication, and costly site changes by making intent crystal clear — early and often.

How do I draw my own floor plans?

Enter your room dimensions (or use Arcadium’s built-in measuring tool on uploaded floor photos), then trace walls with drag handles. Add openings with context-aware placement — doors snap to wall centers, windows respect sill heights. Use the “Auto-Layout” AI feature to suggest functional room zones based on square footage and use case (e.g., “home office with storage” or “open-plan kitchen-dining”).

How do I calculate how many lights I need?

Forget rule-of-thumb math. Arcadium lets you place realistic light fixtures — recessed cans, pendant lamps, LED strips — and instantly see lux levels, shadow patterns, and glare hotspots across your 3D model. Adjust wattage, beam angle, and mounting height to achieve balanced, task-appropriate illumination — verified visually, not theoretically.

Is Arcadium free to use?

Yes — the Free Plan includes unlimited projects, full access to the furniture library, AI rendering in 4 styles, URL sharing, and all core modeling tools. Premium tiers unlock advanced features like BIM export, custom material uploads, team workspaces, and priority support — but you’ll ship stunning designs long before upgrading.

How can I create kitchen layout plans online?

Arcadium’s kitchen module includes pre-configured base cabinets, wall units, islands, countertops (with edge profiles), and integrated appliances — all sized to industry standards. Drag to arrange, then use “Workflow Mode” to simulate cooking paths, check clearance zones, and toggle between U-, L-, and galley configurations. AI even suggests appliance pairings based on your layout and lifestyle preferences.
