How to Build an App Like Planner 5D: Features and Cost

You have used Planner 5D or one of its rivals, and now you are scoping something similar: a home design app where a person draws their room, drops in furniture, and sees it in 3D before they spend a rupee or a dollar on the real thing. The question in front of you is not "is this a good idea". It is "what does this actually take to build, and what will it cost me". This guide answers both from the build side.

One thing up front. Planner 5D is a well known reference brand here, not an appico client, and we have no connection to it. We use it only as a clear example of a category, and every fact we state about it is linked to its own official pages. Everything else is general engineering that applies to any home design app or room design app.

What does an app like Planner 5D actually do?

An app like Planner 5D lets a person draw a floor plan, switch between a flat 2D layout and a walk-in 3D view, and fill the space with furniture from a large catalogue. Planner 5D states that you can "Draw a floor plan and create a 3D home design in 10 minutes" and choose from "More than 8,000 items" in its library (planner5d.com). It runs on web and mobile so a design started on a laptop continues on a phone.

Underneath the friendly screens, an app like this needs three products that behave as one: an editor, a 3D content library, and the output that makes a room feel real. Split them out and the scope becomes clear.

If your product is closer to a pure floor plan and layout tool than a furniture catalogue, read our deeper walkthrough on how to build a 3D room planner app before you lock the spec. It covers the editor and geometry side in more detail than we have room for here. For the wider category of AR shopping and furniture apps, the guide to building an app like IKEA Place is the pillar for this whole cluster.

Which features come first, and on which platform?

Build the editor and catalogue first, renders second, AR third. The editor and the 3D content library are the product; a person can design a full room with those two alone. Renders and AR are strong add-ons that only pay off once the base app works. The table below maps each core feature to its platforms and the one build note that matters most for it.

Read the platform column carefully. The reason a home design app is harder than a normal app is hidden in that column: the same 3D room has to look right in a web browser and in two different mobile operating systems. That single requirement shapes the whole build.

The 3D core: one engine, three platforms

The most important decision in the whole project is how you build the 3D core, because it decides your cost, your team and whether a room looks the same everywhere. The winning approach is one 3D engine with shared scene logic, wrapped in a web build and native mobile shells.

In practice there are two common routes. The first is a web-first 3D stack using a WebGL library such as Three.js or Babylon.js, then reusing as much of that logic as possible inside the mobile apps. The second is a cross-engine like Unity that exports to web, iOS and Android from one codebase. Planner 5D itself is available across web, iOS, Android, Windows and macOS, and tells users to "Start creating on your laptop and finish on your phone or tablet" (planner5d.com), which is only possible when the room lives in one shared format.

Here is the trade-off in plain terms. A web-first stack gives you instant reach, since anyone can open a link with no install, but you fight the browser on heavy scenes and battery. A game engine gives you smoother 3D and easier mobile performance, but a heavier download and a steeper learning curve for the team. Neither is wrong. The choice depends on whether the browser or the phone is your primary home, and getting a senior team to make that call early is worth more than any feature. This is the kind of architecture decision our app development team settles in the first week, before a line of catalogue work begins.

The catalogue is where the budget goes

The furniture catalogue is the real mountain of an app like this, not the screens. A large, well made 3D catalogue is a moat that new apps struggle to cross, which is exactly why Planner 5D advertises its "More than 8,000 items" as a headline feature (planner5d.com). Every one of those items is a 3D model that has to load fast on a phone, look right under light, and exist in the right file format for each platform.

Three things decide whether the catalogue helps you or sinks you:

• File formats. The web and Android world runs on GLB, while Apple's AR uses USDZ. Most items need both, exported cleanly, so a single sofa is really two files that must match. Our explainer on USDZ and glTF file formats covers why this dual export is not optional.
• File size and compression. A model that looks perfect in a design tool can be far too heavy for a phone. Every item needs a sensible polygon budget and texture compression, or the app stutters and the catalogue never finishes loading. The craft of making models this way is its own discipline, covered in how to make 3D models for an AR furniture app.
• Operations at scale. A catalogue is not built once. It grows every month, item by item, with quality checks, naming, categories and versioning. This running work often eats a large share of the total budget. We break down the machine for it in building a 3D model catalogue at scale.

The honest lesson from shipping these: teams under-budget the catalogue by a wide margin. They price the app and treat the models as an afterthought. Start narrow, with a few room types and the most used items, and treat the catalogue as a product line with its own plan and cost.

How do you handle 2D and 3D in one editor?

You handle 2D and 3D by keeping one room model and showing it two ways, not by building two editors. The user draws walls and places items once; the 2D floor plan and the 3D view are two windows onto the same data. Planner 5D describes this as being able to "Switch between 2D and 3D views to review the layout and see how your choices work together" (planner5d.com/use/home-design-software).

The engineering care goes into the join between the two. Snapping walls to a grid, keeping doors and windows attached when a wall moves, and holding real scale so a three metre wall is three metres in both views. Get the shared model right and both views come almost for free. Build them as two separate features and they drift apart, which is the most common reason a home design editor feels buggy.

The AR view: reach against depth

The AR view lets a person point their phone at their real room and see a piece of furniture standing in it at true size. Planner 5D offers this as "AR Projecting", which it describes as taking "a snap of your room" and turning it "into a 3D rendering where you can rearrange furniture" (planner5d.com/use). It is a powerful selling moment, but it is an add-on to the editor, not the heart of the app.

You have two routes for AR, and they trade reach against depth. Native AR, using the AR framework built into each phone, gives you accurate scale, depth and the ability to hide furniture behind real objects, at the cost of a full app install on each platform. WebAR opens straight from a link with no install and reaches almost any modern phone, but with less depth and more limits. We compare the two in detail in WebAR vs a native AR app, and the native framework differences between the two phone platforms in ARKit vs ARCore for AR apps.

The practical call: if AR is a "try before you buy" convenience for people already in your editor, WebAR is often enough to start. If AR is your headline and you need it to feel solid, budget for native, and budget for the devices that do not support it well.

How does the build run, phase by phase?

The build runs in five phases: scope the product, build the shared 3D core, build the editor and catalogue pipeline, add renders, AR and the paid model, then test and ship across every device. The order matters, because the 3D core and the catalogue pipeline carry most of the risk and must be settled before the polish.

Phases look neat on a diagram, but two of them are not like the others. The 3D core and the catalogue pipeline are deep engineering work with real unknowns, while the screens, accounts and settings are ordinary app work. If someone quotes you a home design app as if it were a normal app with a 3D feature bolted on, they have mispriced the hard parts. This is also why turning a rough idea into a real plan pays off early, a step we walk through in how to turn an idea into an app.

How does an app like this make money?

Most home design apps run a freemium model: a free editor pulls people in, then paid plans open more catalogue items, higher quality renders, export, or the removal of limits. Planner 5D confirms this shape plainly, stating you can use it "as free home design software" while "Paid plans are available for access to more items and features" (planner5d.com/use/home-design-software).

The trap in freemium is that the free tier is a real cost, not a free gift. Every free user consumes storage, catalogue bandwidth and, if you offer them, cloud renders that run on servers you pay for. So the paid gate and the render economics decide whether the model works. Common paid gates are the size of the catalogue a user can reach, the number or quality of renders, high resolution export, and saving more than a set number of projects. Some apps add affiliate income by linking placed items to real products for sale. We work through the full set of models, and where each one breaks, in how room planner apps make money.

What does it cost to build an app like Planner 5D?

Cost depends almost entirely on how much 3D you take on, not on the number of screens. A tightly scoped MVP, one platform, a small catalogue and no AR, starts at appico's published MVP from $10,000. A dedicated mobile app from $12,000. A web-only design tool sits on top of our website from $1,000 base, though a real 3D editor is well above that floor. A full cross-platform product with a large catalogue, cloud renders and AR is a larger build that can reach up to about $150,000 as scope grows, and maintenance is a separate monthly plan, not a one-time line.

Those are our real starting prices, and we will not invent a range for anyone else. The number that moves most is the catalogue: a hundred well made models is a different project from several thousand. To sanity check your own scope against these bands, use our pricing page, and for the room planner category specifically, our cost to build a 3D room planner app breaks the drivers down module by module. If your product leans more web than mobile, our note on the cost to build a web app is a useful second reference.

The three drivers that decide where in the band you land: how many platforms you ship on day one, how large the catalogue is at launch, and whether AR and cloud renders are in the first release or a later one. Cut any of the three for the MVP and the number drops sharply.

When building an app like Planner 5D is not worth it

Building an app like this is not worth it when you cannot fund the catalogue or when a simpler tool would serve your real goal. The category has strong, free incumbents with catalogues built over years. If your plan is to match them feature for feature on day one, the honest answer is that you cannot, and you should not try. Three cases where we would tell a client to stop or change course:

• You need the whole thing at once. If the product only makes sense with a huge catalogue, AR, renders and three platforms from launch, and the budget is MVP sized, the maths does not work. Narrow the scope or wait.
• Your real need is one room type. A kitchen planner, a wardrobe configurator or a single-product visualiser is a far smaller and safer build than a general home design app. If that is your business, build that, not a Planner 5D clone.
• You are a retailer who wants placement, not design. If your goal is to let shoppers see your own products in their room, an AR furniture feature on your store is cheaper and converts better than a full design studio. The app like IKEA Place approach fits that goal better.

None of this means the category is closed. It means the winners pick a wedge, a room type, a region, a price point or a level of realism, and own it before they widen out.

Our take

An app like Planner 5D is not one build, it is a 3D engine, a content operation and an ordinary app stitched into a single product. Teams that succeed respect the first two and do not treat them as features. They pick one platform and a narrow catalogue to launch, prove the editor and the paid gate work, then widen. Teams that fail try to match a decade of catalogue on an MVP budget.

If you are scoping one of these, the useful next step is to fix the wedge and the first platform, then price only that. We build home design and 3D room tools with a senior India team, at fixed transparent cost, and you own the code, the models and the accounts from day one. Tell us your room type and your first market, and we will scope a first version that ships. Start on our app development page.
