Space Designer 3D is an online floor plan software used by over 6 million people worldwide since 2010. It runs entirely in the browser, with no download or installation required. You draw your floor plans in 2D, furnish your spaces, and see the result in real-time 3D. For a layout example, see this spacious three-bedroom house with modern comfort.
Why Kozikaza Closed
Kozikaza was a French 3D home design platform launched in 2011. It was popular in France for its simplicity, its free plan, and its active community where users shared their projects and exchanged tips.
The site was acquired by Leroy Merlin. Since the closure, kozikaza.com redirects to Leroy Merlin's 3D floor plan tool. For former users, this means:
- Projects saved on Kozikaza are no longer accessible.
- The community and comments are gone.
- The 3D floor planning, rendering, and sharing features are no longer available in that form.
If you had plans saved on Kozikaza, there is unfortunately no way to recover them. You will need to recreate them in another floor plan tool.

2D and 3D Floor Plan Design
Kozikaza let you draw walls, adjust their thickness, place doors and windows, and design multiple floors. The interface was straightforward and built for homeowners without any architectural background.
Space Designer 3D covers all of these features and adds practical tools to speed up your workflow:
- Automatic measurements: dimensions are calculated in real time between every element in your plan, including walls, openings, and furniture. No manual measuring needed.
- Instant 2D/3D sync: every change you make to the floor plan is reflected immediately in the 3D view.
Whether you're planning a renovation or designing a new build, you can create a 3D house plan online in just a few minutes, with no drafting experience required. Space Designer 3D is home design software available with a free plan.
3D Visualization and Virtual Tour
Kozikaza's 3D view worked with a single click: the 3D model was generated automatically from the 2D floor plan, giving you a clear sense of volume and layout.
Space Designer 3D works the same way, with additional tools on top:
- Real-time lighting and shadows: the 3D mode renders light and shadow dynamically, producing a more realistic preview of your space.
- Solar orientation: enter your project's address to simulate actual sunlight at different times of day. Useful for optimizing room layout based on natural light.
- Sections and elevations: view your home's structure as a vertical cross-section, essential for building permit applications.
- Virtual tour: walk through your project in 3D as if you were actually there.
- Virtual reality: explore your design in VR for a fully immersive experience.
Interior Design and Furniture Catalog
Kozikaza's catalog included furniture, appliances, decor, and outdoor elements such as gardens, patios, and plants.
The Space Designer 3D catalog contains over 5,000 items. Every element can be customized in size, color, and finish to suit your project. Floor coverings and wall paint are fully adjustable. See it in this traditional villa with a modern interior.
For professionals, including real estate agencies, furniture manufacturers, and interior designers, the Business and Enterprise plans allow you to integrate your own branded product catalog.
Photorealistic Rendering
Kozikaza let you generate HD screenshots and 360-degree panoramas.
Space Designer 3D offers the same capabilities, with added control over rendering settings. You can adjust lighting, textures, and the environment before generating an image. Resolution goes up to 8K, producing professional-quality visuals suited for building permit files or presenting your project to a contractor.
In practice, you can simulate the mood of a room at different times of day, fine-tune reflections and shadows, and get results that look close to a real interior photograph. You can see this in finished renders like this modern villa immersed in nature with a pool.
Sharing and Collaboration
Kozikaza was primarily a community platform: users published their projects, commented on each other's work, and exchanged advice. This is something many former users miss.
Space Designer 3D takes a different approach, focused on private collaboration:
- Invite collaborators to a project, whether that's family members, an architect, or an interior designer.
- Set permissions: read-only or full editing access.
- Comment and annotate directly on the plan.
- Export your plans as PDFs, images, sections, elevations, or shareable 3D tour links.
This approach works equally well for homeowners who want to share a project with a friend or family member and for professionals working as a team on a floor plan.
