Home Designer Suite - 2026

Home Designer Suite is the complete interior architecture toolkit for Unity: draw floor plans procedurally, place furniture from a modular library, paint materials per room or per surface, and preview realistic multi-floor buildings in real time, all without leaving Play mode.

This is the next generation of the older Floor Plan Designer and Home Designer plugins, rewritten from the ground up with a new architecture, a richer API, mobile support, undo/redo, smart snapping, and a redesigned UI. If you already own either of those two plugins, you qualify for a loyalty discount of 25 to 60% depending on what you previously paid: submit your invoice at homedesigner.exoa.dev/discount.

The floor plan editor lets you draw arbitrary polygon rooms or snap to a rectangular shortcut, split any room into multiple areas with a single gesture, and place doors, windows, and archways by drag and drop. Every change rebuilds the geometry procedurally in real time, including walls, floors, ceilings, UV maps, and collision meshes.

Furniture comes from an included library of 63 ready-to-use prefabs across categories like appliances, bedroom, kitchen, living room, lighting, and patio. Objects snap automatically to floors, walls, and ceilings through a single-collider snapping system, rotate in 15-degree steps, and scale on screen without writing code. Materials can be applied per room, per wall, per floor, or per ceiling, with full support for Built-in, URP, and HDRP; a batch Render Pipeline Switcher tool converts all materials in one click.

A stacked multi-floor preview shows every floor at once, including furniture, exterior shell, and roof geometry, with smooth transitions and automatic camera refocus. For anything the Editor UI doesn't cover, the HeadlessBuildingAPI creates, modifies, and serializes entire buildings directly from code with no UI dependency, useful for batch-generating building variations or wiring the builder into a custom pipeline.

Every action is snapshotted as JSON, so you can step backward and forward through up to 50 states with a full geometry rebuild at each step. Finished designs export to JSON for data-driven workflows or GLB for real-time 3D rendering, both usable at runtime without leaving Play mode, with support for loading, saving, and enumerating multiple named project files.

Touch controls are fully optimized for Android and iOS: multi-touch pan, pinch-to-zoom, long-press drag, and tap-to-select all work out of the box. The suite also ships with a complete, self-hosted Laravel web application you can host on your own server, giving your users a portal to save and load projects from anywhere, browse public community templates, and manage accounts. It's open source, with no vendor lock-in.

What's included

• 63 furniture prefabs across appliances, bedroom, kitchen, living room, lighting, and patio
• Redesigned, fully animated UI with full undo/redo history (up to 50 states)
• HeadlessBuildingAPI for full programmatic control, with a real-time event system
• Smart snapping: one collider makes any GameObject a placeable module
• Multi-floor preview, public template system, and customizable keyboard shortcuts via the HomeDesignerInputActions asset
• JSON and GLB export for runtime-ready results
• Demo_Editor and Demo_API example scenes
• Render Pipeline Switcher and Convert GameObject to Module editor tools
• Self-hosted website with a user account system and project management, open source
• Full C# source code (160+ scripts) and complete documentation: API reference, architecture diagrams, integration guides, and FAQ
• Android and iOS support
• Dedicated support forum

Under the hood

The suite is built as an event-driven architecture: a state machine (Idle, Floors, FloorPlan, Paint, Furnish, Preview) drives every screen through subscribers rather than hardcoded logic, and a Service Locator pattern handles dependency injection so the UI can be swapped or removed without touching the core. It totals over 160 C# scripts across more than 20 controllers and 30 UI components, with 9 procedural mesh generators covering rooms (walls, floor, ceiling, reflection probe, collision mesh), exterior areas, openings, the exterior shell, and three roof types (flat, hipped, and gabled) with configurable overhang and thickness. Construction settings, including wall height, interior and exterior wall thickness, door height, roof type, roof thickness, and roof overhang, are all configurable at runtime, and a scene can run multiple BuildingController instances at once, or none at all if you're driving everything through the HeadlessBuildingAPI.

Common questions

Is this a subscription? No. It's a one-time purchase: a perpetual license with free minor and patch updates and priority email support.

What Unity versions and render pipelines does it support? Unity 2022.3 LTS and above, including Unity 6 LTS, with full compatibility across Built-in, URP, and HDRP; a batch Render Pipeline Switcher tool is included to convert existing materials between them.

Can I generate buildings from code instead of using the Editor UI? Yes. The HeadlessBuildingAPI creates, modifies, and serializes entire buildings with no UI dependency, which is also how the included Demo_API scene works.

I already own Floor Plan Designer or Home Designer. Do I have to pay full price? No. Home Designer Suite supersedes both plugins, and existing owners qualify for a loyalty discount of 25 to 60% depending on what they previously paid: submit your invoice at homedesigner.exoa.dev/discount.

What's planned next? The public roadmap includes parametric, constraint-based rooms, rounded wall corners, floor plan scanning from an image or PDF, and an online modules library for downloading curated furniture packs directly in the Editor.
