Sweet Home 3D

Overview

Sweet Home 3D is an interior-design application for drawing dimensioned home plans and viewing them in 3D. It suits homeowners and design learners who want precise layouts alongside visual presentation. Its mix of free desktop access, live views and broad export options is compelling, though the free editions have smaller catalogs than the paid subscription.

Key features

Measured plans and live views

Draw straight, round or sloping walls with precise dimensions, then add room areas, dimension lines, text, arrows and a compass rose. A live 3D view follows the 2D design, with aerial and virtual-visitor perspectives. That combination helps connect measurements to the appearance of a space; the annotations also make plans more useful for communicating a layout than an unmarked sketch.

Rendering and file support

Sweet Home 3D creates photorealistic images and videos with customizable lights and sunlight settings tied to time of day and geographic location. It can import blueprints, 3D models and textures, and print or export PDFs, bitmap or vector images, videos and standard-format 3D files. This is a flexible set of presentation and exchange options for a home-planning tool. Real-time scenes and video export are supported.

Catalogs and extensions

The free desktop bundles have smaller furniture and texture catalogs; the Windows bundle includes 100 furniture items and 26 textures. The maker advertises a full version with more than 10,000 3D models and 400 textures. Java plug-ins can add capabilities, with extensions for tasks such as generating roofs, staircases, terrain and HTML5 views. The smaller free catalog is a meaningful trade-off for users who want a broad choice of ready-made objects.

Browser access and support

Sweet Home 3D Online Manager runs in a WebGL-compatible browser without installation, but requires free registration to save a design. Documentation, a user guide, video tutorials, FAQs, a forum and contact links provide several support routes.

Pricing

The pricing model is freemium, with a free plan and a free trial on the paid subscription.

The free edition is the sensible starting point for measured plans and 3D views if its smaller catalog is enough. Monthly Premium is aimed at users who need the larger catalog. It renews automatically unless turned off at least 24 hours before the period ends; the price may vary by country.

The free application is distributed under the GNU General Public License, which the maker says permits personal and commercial use. The GPL also prevents developers who do not own Sweet Home 3D copyrights from making proprietary programs derived from or incorporating it; users interested in other licenses are directed to ask about them.

Platforms

Sweet Home 3D is listed for Android, iOS, Linux, macOS, web and Windows, with an extension also listed. Desktop downloads cover Windows, macOS and Linux; the browser version requires WebGL compatibility. Mobile viewing is supported, and the product is categorized as hybrid.

Who it's for

Homeowners and design learners can use the measured 2D plan and live 3D view to work through a layout. The maker also describes professional uses for architects, interior designers, furniture retailers and manufacturers, real estate and event planners. Plug-ins and multiple export formats extend its usefulness for projects that need additional capabilities or portable outputs.

It is less suitable for someone who needs the largest furniture and texture selection without paying, or for developers who want to build a proprietary product derived from or incorporating the GPL application without holding its copyrights.

Pros and cons

• Pros: Precise walls, dimensions and plan annotations support more than rough room sketches.
• Pros: A live 3D view, photorealistic image and video rendering, and multiple export formats serve both planning and presentation.
• Pros: Free desktop editions and browser access provide ways to work without a subscription; the application is GPL-licensed for personal or commercial use.
• Cons: Free desktop bundles have smaller catalogs than the advertised full version, which may limit users who rely on a wide choice of models and textures.
• Cons: Saving a design in the browser requires free registration.
• Cons: The monthly subscription renews automatically unless canceled at least 24 hours before the period ends.

Alternatives

For other options, compare 3D Visualization Software, 3D Home Design Software and Floor Plan Software.

• Planner 5D is another freemium option with a free plan and trial; its Premium plan is $59.99 a year and includes floor-plan upload and conversion to a 3D project plus a full premium furniture catalog. Choose it if those stated capabilities and annual billing suit your needs better.
• RoomSketcher has a free plan with 2 credits to start, one free AI floor-plan conversion, 2D and 3D floor plans, 3D snapshots and AI Render. It is a relevant alternative if those free-plan tools match your project.
• Coohom offers a free Starter plan with a 3,000-plus furniture catalog, 10 renders per month and 3 shareable links, but no 360° panorama or photo-to-3D image conversion. Choose it if its larger free catalog and rendering allowance are more useful than Sweet Home 3D's measured drawing and export mix.
• Live Home 3D has a free app, with Standard and Pro subscriptions and lifetime licenses offered in-app.
• Arkio has a free Starter plan with all modeling tools, 1:1 meetings and OBJ/GLB and image import and export; its Pro plan is $35 a month. Consider it if those tools or its stated upgrade fit your needs.
• Homestyler offers a free Basic plan with unlimited 1K rendering and more than 100,000 free 3D models and materials; 4K renders are purchased separately. It may suit users prioritizing that free catalog and rendering allowance.
• Kuula has a free Basic plan capped at 300 posts and 100 uploads per month, with self support.
• Matterport has a free plan limited to one active space and two users, with limited camera support.

Verdict

Choose Sweet Home 3D if you want measured 2D home plans linked to a live 3D view, plus rendering and varied export options, without paying to get started. Look elsewhere if a large ready-made catalog is central to your work and the smaller free bundles will not do; the paid subscription's automatic renewal also merits attention.
