Download Sweet Home 3D — Free 2D Floor Plan and 3D Home Designer for Windows PC v7.5 for Windows PC

Sweet Home 3D 7.5 lets you draw a measured 2D floor plan with walls, rooms and dimensions while seeing it in 3D at the same time, then furnish it, render...

Features

• The measured 2D plan and the 3D view update together in real time, so every wall, door, window and sofa you place can be judged instantly from several angles.
• Walls, rooms and dimension lines follow real measurements as you draw, which lets a finished plan stay accurate enough to print properly to scale for builders and shop staff.
• Doors, windows and everyday furniture come from a built-in library organised by room that covers ordinary homes well, so a complete first layout needs no external models at all.
• Extra furniture and objects can be imported in OBJ, DAE, 3DS and LWS formats, greatly expanding the dated built-in catalogue for free.
• Photos and videos of the 3D view can be rendered and shared, which helps family members or contractors understand a proposal quickly.

Considerations

• Rendered images look distinctly basic beside professional interior design tools, with simpler lighting, shadows and surface materials that clearly limit presentation-quality output for paying clients or property marketing material.
• The stock furniture library feels noticeably dated in style and finish, so matching a genuinely modern interior usually means hunting down, downloading and importing extra third-party models from the web.
• Very large multi-floor plans with many imported models can get sluggish, making big houses noticeably less pleasant to edit smoothly.

Sweet Home 3D's screen explains itself in seconds: a measured 2D plan occupies one pane and a live 3D view of the same space sits in another. Draw a wall and it rises in 3D; drag a sofa across the plan and it moves in the room. That simultaneity is the program's whole philosophy, because most homeowners think in floor plans when measuring and in rooms when judging, and Sweet Home 3D refuses to make them choose. The drawing tools respect real dimensions, with walls, rooms and dimension lines that keep a plan accurate enough to print to scale for a builder. Doors and windows cut their own openings, furniture arrives from a built-in library organised by room, and textures and colours apply to walls and floors with a click. Beyond the basics, the import wizard accepts OBJ, DAE, 3DS and LWS models, unlocking vast free libraries of modern furniture. Finished views become rendered photos or walk-through videos at chosen quality levels, and virtual visitor mode lets you stand inside the design at eye height — the moment most users finally trust a layout.

Sweet Home 3D suits homeowners and tenants planning real changes: a kitchen refit, a nursery conversion, a furniture purchase that must be proven to fit before money moves. Its measured plans print to scale, which builders and patient family members appreciate, and its learning curve is measured in an evening rather than a course. Landlords sketching rental layouts and teachers demonstrating spatial planning also get full value from a free, open-source tool with no licences to manage. Start elsewhere if your work is professional presentation. Interior designers selling concepts to clients will find the rendered lighting and materials basic, the stock furniture dated, and the polish of paid suites worth their subscriptions. Architects needing construction documentation, structural detail or code compliance require proper CAD or BIM software such as FreeCAD or commercial tools — Sweet Home 3D deliberately stops at design visualisation. Very large multi-floor projects can also slow as imported models accumulate. Judged on its intended ground — helping ordinary people see a room clearly before changing it — the program's focus is a virtue, not a limitation.

A common session begins with a tape measure rather than the program: the living room is four by five metres, the radiator sits under the window, and the door swings where a bookshelf was planned. Back in Sweet Home 3D you draw those walls to the real dimensions, place the door with its correct swing, and add the window and radiator so the constraints exist from the start. The 3D view immediately shows how tight the corner already is. Next, the existing sofa and the larger replacement under consideration are dragged in from the library and resized to their catalogue measurements. The bigger sofa fits the wall but blocks the door's swing in the plan — visible in seconds, before any purchase. You rotate the layout, swap in imported models of two armchairs instead, and walk the room in virtual visitor mode to check the view from the doorway. A rendered photo goes to the family chat, the plan prints to scale for the shop visit, and the session ends with a buying decision made on evidence rather than optimism.

Download SweetHome3D-7.5-windows.exe and double-click it, then follow the setup wizard to install the free desktop edition on your Windows PC.

Launch Sweet Home 3D, create the walls of one room using real measurements, and add a door and window while watching the 3D view build beside the plan.

Drag furniture from the library into the plan, adjust the 3D view, then render a photo of the room or print the finished plan to scale.

Is Sweet Home 3D really free?

Yes, the desktop edition listed here is free and open source under the GPL, with no time limit, watermark or feature-locked plan editor. You can draw plans, furnish rooms, render photos and print to scale without paying. Separate mobile apps exist for phones and tablets and are sold as different products, so do not confuse their store pricing with this free Windows desktop version from eTeks.

Can I import my own furniture models into Sweet Home 3D?

Yes, Sweet Home 3D imports furniture and objects in OBJ, DAE, 3DS and LWS formats through its furniture import wizard, which lets you set size, orientation and placement before the model joins your library. Large free model libraries online use these formats, so you can replace the dated built-in pieces with modern sofas, appliances and decorations. Keep polygon counts sensible, since very heavy models slow down large plans.

How to create a 3D representation of your house

Start by drawing the ground-floor walls on the 2D plan using your real measurements, then add rooms, doors and windows so the shell is correct. The 3D view builds itself as you draw, so switch viewpoints to walk through the space and spot mistakes early. Furnish from the library or imported models, adjust colours and textures, then render a photo or video and print the plan to scale for reference.

How can I recover Sweet Home 3D so it will start again?

If Sweet Home 3D stops starting, first restart Windows and relaunch it before changing anything, since a stuck background process is a common cause. If it still fails, update or reinstall version 7.5 over the existing installation — your saved homes are separate files and are not deleted. Problems that begin after adding a plug-in are usually fixed by removing that plug-in, which restores the program without a full reinstall.
