Sweet Home 3D

Overview

Sweet Home 3D is a home-planning and interior design application for people who want to turn measured layouts into a viewable 3D space. It suits homeowners, students and design professionals who need both annotated plans and visual presentations. Its combination of precise 2D drawing, live 3D viewing and broad export options makes it a capable general-purpose choice, though catalog size and licensing deserve attention.

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. Those annotations make the 2D plan more useful for communicating a layout, rather than merely sketching one. A live 3D view updates alongside the plan and offers aerial and virtual visitor perspectives, helping users inspect both the overall arrangement and the space at eye level.

Rendering, catalogs and extensions

Sweet Home 3D can produce photorealistic images and videos with customizable lights and sunlight keyed to time of day and geographic location. That is useful for presenting a design under different lighting conditions, while video export adds a more guided way to show a space. It imports blueprints, 3D models and textures, and prints or exports PDFs, bitmap or vector images, videos and standard-format 3D files.

Catalog size varies by edition: the maker advertises more than 10,000 models and 400 textures in the full version, while free desktop bundles have smaller catalogs; the Windows bundle includes 100 furniture items and 26 textures. Java plug-ins can add capabilities, with extensions for tasks such as roofs, staircases, terrain and HTML5 views. These options broaden the application, but buyers choosing a free edition should check whether its included catalog is adequate for their project.

Browser and learning resources

The Online Manager runs in a WebGL-compatible browser without installation, but users must register for free to save a design. Documentation, a user guide, video tutorials, FAQs, a forum and contact links provide several routes to help. The school offering targets design and architecture projects on Windows, macOS and Linux.

Pricing

The free edition is the sensible starting point for personal projects, classroom use or commercial work that fits the GPL and does not require a larger catalog. The Microsoft Store subscription is aimed at users who want its larger catalog and are comfortable with recurring billing. It renews automatically unless turned off at least 24 hours before the period ends, and 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 under that license. The same license constrains developers: those who do not own Sweet Home 3D copyrights cannot make proprietary programs derived from or incorporating it. Developers seeking that kind of use are directed to ask about other licenses.

Platforms

Sweet Home 3D spans Android, iOS, Linux, macOS, web and Windows, with extension support also listed. Desktop downloads cover Windows, macOS and Linux; the online version is browser-based and requires registration to save designs. Mobile viewing is supported, while the listed school offering is for desktop systems.

Who it's for

Homeowners can use it to draw and inspect a proposed layout; architects, interior designers, furniture retailers and manufacturers, real estate professionals and event planners are among the professional audiences described by its maker. Its school offering is suited to teaching design and architecture concepts through 2D and 3D projects. It is less suitable for a developer whose goal is a proprietary product derived from or incorporating the GPL application without an alternate license.

Pros and cons

• Pros: Precise dimensions and plan annotations make layouts more communicative than unmeasured sketches.
• Pros: Live 3D views, photorealistic rendering and video export support both inspection and presentation.
• Pros: Imports and exports cover blueprints, models, textures, PDFs, images, video and standard 3D files.
• Cons: Free desktop bundles have smaller catalogs, which may limit furniture and material choices.
• Cons: Saving in the browser requires free registration, and the premium subscription renews automatically unless canceled in time.
• Cons: The GPL licensing constraint rules out proprietary derivatives for developers who do not own the copyrights, absent another license.

Alternatives

Coohom is a better fit for users who prioritize a 3,000+ furniture catalog and 10 monthly renders in a free plan, with three shareable links; its free plan excludes 360° panoramas and photo-to-3D conversion. Live Home 3D is another freemium option for users comparing home-design software across iPhone, iPad, Vision, Android, macOS and Windows.

Planner 5D may suit users who want floor-plan upload and conversion to a 3D project, a full premium furniture catalog and standard renders in its Premium plan at $59.99 a year. RoomSketcher is worth considering for users who want to begin with two credits, one free AI floor-plan conversion, 2D and 3D floor plans, snapshots and AI Render.

HomeByMe is an option for users who value a free Starter plan with two projects, five Full HD images, unlimited 2D/3D screenshots and a 90,000+ product catalog. Homestyler may be preferable when a large free library matters: its Basic plan includes unlimited 1K rendering and more than 100,000 free 3D models and materials, while 4K renders are purchased separately.

Kuula is a separate freemium option for readers considering a service with a free Basic plan capped at 300 posts and 100 uploads per month. Matterport is another alternative, with a free plan for one active space and two users, plus limited camera support.

For a broader shortlist, compare 3D Visualization Software, 3D Home Design Software and Floor Plan Software.

Verdict

Sweet Home 3D is a strong choice for people who need dimensioned plans, a synchronized 3D view and flexible ways to present or export a design without an upfront desktop cost. Its principal trade-offs are smaller free catalogs and the GPL constraint on proprietary derivatives. Choose it for measured home planning and visualization; look elsewhere if a larger ready-made catalog is essential or your software business needs a proprietary derivative.
