5 Best Free Interior Design Apps for Singapore Homeowners (2025)
Before you commit to a layout, it helps to see it. These five free apps are genuinely useful for planning an HDB renovation or condo redesign — no paid subscription needed for the core features.
1. Planner 5D
The most full-featured free option on this list. You draw a floor plan, then furnish it in 2D or flip to 3D to walk through the space. The furniture catalog is large enough to approximate most common layouts, and the 3D view is good enough to test whether a sofa actually fits without blocking the walkway.
The free tier covers most of what you need. Some premium furniture items are paywalled, but the free catalog handles standard HDB room sizes fine.
Platforms: iOS, Android, Windows, macOS Try Planner 5D
2. Roomstyler 3D Home Planner
Web-based, so nothing to install. You drag furniture into a room outline and switch to 3D to see how it looks. What makes Roomstyler useful is the real-world brand catalog — actual pieces from actual retailers, so you can see roughly what a specific sofa or lighting fixture looks like in your space before buying.
Works well for anyone who already has a shortlist of furniture and wants to see how it all fits together.

3. Homestyler
Homestyler has an AR feature that lets you point your phone at a room and place virtual furniture in it. It is not perfectly accurate, but it is useful for a quick sanity check — does a king bed actually fit in this master bedroom, or does it look ridiculous?
The full 3D design mode is also solid. Good choice if you want both a planning tool and something you can use on-site during a showroom visit.

4. MagicPlan
MagicPlan does something the others do not — it measures your room automatically. Point your phone's camera at the corners of the room and it generates a scaled floor plan. For resale HDB flats where official floor plans are often unavailable or outdated, this is genuinely handy.
The free version gives you the floor plan and basic furnishing. Exporting to PDF or sharing with a contractor requires a paid plan.
Platforms: iOS, Android Try MagicPlan
5. Floorplanner
Clean and fast. Draw a floor plan in 2D, then switch to 3D to check proportions. The interface is simpler than Planner 5D, which makes it easier to pick up if you just need something quick.
The free account gives you one saved project. Enough for testing a single room or apartment layout.

Which one should you use?
For most Singapore homeowners planning an HDB or condo renovation: start with Planner 5D for the full floor plan, and use MagicPlan if you need accurate room measurements first.
That said, no app replaces an actual space plan from your interior designer — the details matter more than the software. If you want a proper layout drawn up for your space, request a free consultation and we'll take it from there.
