What it is

Sweet Home 3D is an interior design application for drawing home plans and viewing them in 3D. In its 2D plan, users can draw straight, round, or sloping walls with precise dimensions and add room areas, dimension lines, text, arrows, and a compass rose. A live 3D view shows the design from above or from a virtual visitor’s perspective as the plan is built. The software can render images and videos with adjustable lights and sunlight based on time of day and geographic location. It imports blueprints, 3D models, and textures, and can print or export PDFs, images, videos, and 3D files in standard formats. The free desktop and online version costs nothing; downloadable editions have smaller furniture and texture catalogs. Sweet Home 3D Online Manager runs in a compatible browser, but free registration is required to save designs. The Microsoft Store Monthly Premium subscription costs $9.99 a month and includes a 7-day free trial. Desktop editions are available for Windows, macOS, and Linux.

Sweet Home 3D in depth

Read the full write-up

Overview

Sweet Home 3D is a home-planning and interior-design application built around measured 2D drawings and a live 3D view. It suits homeowners, students and design professionals who need to shape and present a layout; its strongest appeal is the combination of precise plans, visual review and broad export options. Catalog size is the key trade-off between its free editions and paid Store 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. That makes the plan useful for communicating spatial decisions, not just sketching a room. A live 3D view updates alongside the 2D design, with aerial and virtual-visitor perspectives for considering the layout from different angles.

Rendering, imports and extensions

Photorealistic images and videos can use customizable lighting and sunlight settings tied to time of day and geographic location. Import support for blueprints, 3D models and textures, plus export to PDF, bitmap or vector images, video and standard 3D files, gives the application useful flexibility when sharing work or moving assets between tools.

Java plug-ins extend the application, with maker-listed extensions for roofs, staircases, terrain and HTML5 views. The maker also provides documentation, a user guide, video tutorials, FAQs, a forum and contact links. The application is distributed under the GNU General Public License, which permits personal and commercial use under that license; developers seeking to build proprietary derived or incorporated software need to ask about other licensing.

Pricing

Free desktop and online

The Free desktop / online version costs nothing. Desktop downloads are available for Windows, macOS and Linux; the browser-based Online Manager runs in a WebGL-compatible browser without installation, but requires free registration to save designs. Free downloadable editions have smaller furniture and texture catalogs, so this is the sensible starting point for personal planning or learning, but less attractive if a larger built-in library is central to the work.

Microsoft Store Monthly Premium

The Microsoft Store Monthly Premium plan costs $9.99 a month and includes +1600 furniture items and +400 textures, with limited features available free and a 7-day free trial. The subscription renews automatically unless turned off at least 24 hours before the period ends; price may vary by country. It is the better fit for users who need the larger catalog, while the free edition keeps the core planning workflow available without a recurring charge.

Platforms

Sweet Home 3D is offered across Android, iOS, Linux, macOS, web and Windows, with an extension platform also listed. The desktop download specifically supports Windows, macOS and Linux; the online version avoids installation but requires registration to save. The school offering runs on Windows, macOS and Linux. Mobile viewing is supported, and real-time scenes and video export are listed capabilities.

Who it's for

Homeowners can use it to plan and inspect layouts; the school offering is aimed at teaching design and architecture concepts through 2D and 3D projects. The maker also presents professional use cases for architects, interior designers, furniture retailers and manufacturers, real estate businesses and event planners. The measured drawing, live visualization and export options make it more compelling for layout and presentation work than for someone whose main need is simply a large ready-made catalog at no cost.

Pros and cons

Pros: Precise wall drawing and plan annotations support clear, measured layouts.

Pros: Live 3D viewing, photorealistic renders and video export span planning through presentation.

Pros: Blueprint, model and texture imports pair with PDF, image, video and 3D exports.

Cons: Free desktop editions have smaller furniture and texture catalogs than the full version.

Cons: Saving an online design requires free registration.

Cons: The paid Store option is a monthly auto-renewing subscription, and cancellation must be made at least 24 hours before renewal.

Alternatives

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

Planner 5D is worth considering if an annual Premium plan that converts an uploaded floor plan into a 3D project and unlocks its full premium furniture catalog suits your workflow; it costs $59.99 a year. Live Home 3D is another freemium option, with an iPhone, iPad and Vision free app and in-app Standard and Pro subscriptions and lifetime licenses. Consider Arkio if you want a free Starter plan with all modeling tools, 1:1 meetings and OBJ/GLB and image import/export, or its Pro plan at $35 a month.

RoomSketcher may fit users who want to start with two credits, one free AI floor-plan conversion, 2D and 3D floor plans, snapshots and AI Render. CloudPano offers a free tier and a Pro plan at $22.50 a month billed annually. Coohom is a free-forever alternative with a 3,000+ furniture catalog, 10 renders per month and three shareable links. Realsee is a freemium option for capturing, uploading, editing, previewing and storing; generation or active hosting may use credits depending on capture method. Nanome has a free web seat capped at three workspaces, one project, 50 MARA credits, five most recent files and seven days of chat history.

Verdict

Choose Sweet Home 3D if you want measured home plans, live 3D review and flexible ways to present or export a design, with a free desktop route to get started. Look elsewhere if a large furniture and texture catalog is essential without a subscription, or if the Store plan’s monthly renewal does not suit you.

Verdict

Sweet Home 3D brings measured 2D planning and live 3D viewing into one application, with multiple import and export options. The free desktop and online options have catalog or registration constraints; the Microsoft Store subscription is $9.99 a month.
