Sweet Home 3D is capable software. But if all you need is a clean 2D plan to brief a kitchen fitter, its 3D furniture library, textures, and modelling features get in the way. You end up learning tools you'll never use. Here are six simpler options, compared honestly.
| Tool | 2D-first | No download | No sign-up | Free | Best for |
|---|---|---|---|---|---|
| Free Room Planner | Yes | Yes | Yes | Yes | Fast contractor briefs |
| Sweet Home 3D | No (2D + 3D) | No (install) | Yes | Yes | Hobby 3D visuals |
| Canva | Partial | Yes | No | Freemium | Rough mood-board layouts |
| Excalidraw | Yes (sketch) | Yes | Yes | Yes | Loose concept sketches |
| Plan7Architect | No (3D CAD) | No (install) | No | Paid | Detailed construction plans |
| Cedreo | No (3D cloud) | Yes | No | Paid | Pro designer renders |
Why choose a 2D-first tool over Sweet Home 3D?
A 2D-first tool wins when your goal is communication, not preview. You want a floor plan with real measurements a fitter can order units against — not a photorealistic room you'll never build from. Speed and clarity beat pretty pictures.
Sweet Home 3D asks you to install software, then place furniture in a 3D scene. That's satisfying if you enjoy the process. But most homeowners planning a kitchen or bathroom just need dimensions on paper. The 3D layer adds time without adding accuracy.
In practice, the mistake people make is over-tooling. You don't need best free 3D home design software to tell a contractor where the sink goes. You need a plan that snaps to a grid and shows the numbers.
The 6 alternatives, compared
1. Free Room Planner — fastest for contractor briefs
Free Room Planner is a browser-based 2D tool built for one job: draw your room, add units and furniture, export a clean plan. No download. No sign-up. No payment.
Walls snap to a precise grid and dimensions update live as you drag — grid snapping and live measurements are core Free Room Planner features, so the numbers you share are the numbers a fitter can trust. Export a clean PNG and send it straight to your builder.
What it doesn't do: 3D renders, textures, or elevation drawings. That's the point. If you want those, look further down this list. If you want to brief a professional today, start here.
Open the free room planner — Draw your room, drop in units, and send an accurate plan to your fitter in under five minutes.
2. Sweet Home 3D — the tool you're replacing
Sweet Home 3D pairs a 2D floor plan with a live 3D view. It's free, open-source, and has a large furniture library. For a hobbyist who wants to see a room in 3D, it delivers.
The catch: you install a desktop app, and the interface carries features most homeowners never touch. If 2D is all you need, you're paying a learning-curve tax for a 3D view you won't use.
3. Canva — for rough, visual layouts
Canva's floor plan maker works from templates and shapes. It's genuinely easy and browser-based, which is why people reach for it. If you want a tidy diagram for a presentation, it does the job.
But Canva isn't built for accurate measurement. Shapes don't snap to a real-world grid, so a plan looks neat without being dimensionally reliable. Fine for mood-boarding — risky for ordering units.
4. Excalidraw — for loose concept sketches
Excalidraw is a free, no-sign-up whiteboard with a hand-drawn style. Perfect for sketching an idea fast when you're still thinking out loud.
It has no measurement engine, though. Treat it as a napkin sketch that lives in your browser — great for the first five minutes of an idea, wrong for the plan you hand a contractor.
5. Plan7Architect — professional 3D CAD
Plan7Architect is a paid, installed program aimed at detailed construction planning. It handles elevations, section drawings, and terrain — the professional end of the spectrum.
It's overkill for a homeowner sketching a kitchen. Include it only if you genuinely need construction-grade output and are prepared to learn CAD-style software.
6. Cedreo — cloud-based pro renders
Cedreo is cloud software popular with home builders and remodelers who sell to clients using professional 3D renderings. It's fast for pros but sits behind a paid account.
For a one-off renovation brief, the cost and setup don't pay off. It's built for people producing plans for a living, not homeowners planning once.
What about professional features like DWG export and layers?
Most homeowners never need DWG export, layer management, or blueprint import — but if you do, only some tools deliver. Here's who supports what, so you can match the tool to the job without over-buying.
| Feature | Free Room Planner | Sweet Home 3D | Plan7Architect | Cedreo |
|---|---|---|---|---|
| DWG/DXF export | No | Limited | Yes | Yes |
| Layer management | No | Partial | Yes | Yes |
| Blueprint import | No | Yes | Yes | Yes |
| 3D renderings | No | Yes | Yes | Yes |
The honest takeaway: if you need construction drawings a permit office will accept, Plan7Architect or Cedreo are your realistic choices. If you're briefing a fitter or picturing furniture fit, none of that matters — a clean 2D plan does more, faster.

How do you brief a contractor with a 2D plan?
Brief a contractor by handing them a plan with real dimensions, not a rough sketch — accurate numbers prevent the expensive surprises that show up on install day. Follow four steps.
- Measure the room accurately first — our room measurement tips cover the common mistakes.
- Draw the walls to those measurements so the grid reflects reality.
- Add units and fixtures with their true sizes — a 60cm oven unit takes 60cm.
- Export a clean PNG and send it before any ordering happens.
Here's why it matters. A kitchen fitter orders a 60cm oven unit. Your 2D plan shows the gap beside the cooker is 65cm — not eyeballed as "about right." That 5cm difference gets caught before the unit arrives, not on install day when it won't fit. That single check pays for the 10 minutes it took to draw.
Is a free 2D tool accurate enough for ordering units?
Yes — provided the tool uses grid snapping and shows live measurements. Accuracy comes from measuring the room correctly and drawing to those figures, not from 3D rendering. A precise 2D plan is exactly what a fitter needs to quote and order.
The weak link is almost never the software. It's the tape measure. Get your wall lengths right, draw them faithfully, and a simple 2D plan carries every number a professional needs.
This is where 2D-first tools quietly beat heavier software: fewer features means fewer places to introduce error. You draw the walls, the grid keeps them honest, and the export shows the truth.
Which alternative should you pick?
Pick based on your actual goal, not feature counts. Choose Free Room Planner for a fast, accurate contractor brief with no sign-up. Choose Canva or Excalidraw for rough visual ideas. Choose Plan7Architect or Cedreo only if you need construction-grade or client-facing 3D output.

Frequently Asked Questions
Short answers to the questions homeowners ask most when moving away from Sweet Home 3D.
Is Sweet Home 3D free?
Yes, Sweet Home 3D is free and open-source. The trade-off is that you install a desktop app and work with combined 2D and 3D views, which is more than most homeowners need for a simple contractor brief.
Do I need 3D to plan a kitchen or bathroom?
No. A 2D plan with accurate measurements tells a fitter everything needed to order units and fixtures. 3D helps you picture the finished look, but it adds no accuracy to the numbers your contractor works from.
What's the best free floor plan software with no download?
Browser-based tools that run in your web browser avoid installs entirely. Free Room Planner, Canva, and Excalidraw all work this way. For accurate, orderable plans, choose one with grid snapping and live measurements — see our no-download software guide.
How do I draw floor plans accurately without CAD software?
Measure each wall carefully, then draw to those figures in a grid-snapping tool so lines lock to real dimensions. Skip freehand sketching. Our step-by-step method on how to draw floor plans accurately walks through it.
Can I use Canva as a Sweet Home 3D alternative?
You can, for rough or presentation-style layouts. Canva is easy and browser-based, but its shapes don't snap to a real-world grid, so plans look tidy without being dimensionally reliable. Use it for ideas, not for ordering units.
