Getting started

Open the editor

Go to the app from any modern browser. Nothing to install: the editor loads in the page. You can start drawing immediately — an account is not required for the free plan. The same tools work for a home, a shop floor or an office layout.

Start from an example

The welcome gallery offers ready-made plans grouped by kind — flats, houses, an apartment building, and shops and offices. Each one shows a technique you may want for yourself: a basement reached by a straight flight, a mezzanine on a spiral stair, a conservatory, dormer bedrooms lit by skylights, a corner shop with a glazed front, an open-plan office floor, a warehouse with a loading dock. Open one, then change anything in it.

Or start from a random building

In a hurry, or just curious? The magic wand above the catalogue draws a whole building for you — rooms, doors, windows, furniture, roof and garden. It first asks a few short questions, and every one of them already answers "Any": you only pick what you care about.

"Surprise me" skips the questions entirely and draws everything at random. Whatever you choose, the result replaces the current plan and a single undo brings it back.

• What kind of building — house, flat, apartment building, shop or warehouse
• What size, and how many levels
• Pitched roof or flat roof
• What sits around it — a garden, a pool, or nothing at all

Draw a first room

Choose a room type from the catalogue (living room, bedroom, kitchen…) or draw a free wall. Click or tap to place corners; close the shape to create the room. Dimensions appear as you draw and can be edited afterwards.

Add openings

Doors and windows snap to walls. Drag them from the catalogue onto a wall in 2D or in the 3D view. Planaira keeps them on the wall and warns when they would overlap.

Let Planaira fill in the blanks

Three helpers at the top of the catalogue finish what the plan already implies, and each counts as a single undo. They never touch what you placed yourself.

• Add openings — a door on the wall that serves the room best, then windows on the outside walls, sized to the room
• Furnish — a recipe per room type and size; select a single room to furnish only that one
• Fence the plot — a hedge around the ground, taller on the street side, with a gate lined up with the front door

Set the basics

Settings hold what belongs to the whole project: wall height (from 2.00 m to 4.00 m, with a chip to return to your region’s usual value), wall thickness, and the unit system. The 3D view follows while you drag and reframes when you let go; anything that no longer fits under the ceiling is brought back under it, in one undo step.

Save and come back

Plans are stored locally in your browser (IndexedDB). Open the project name in the top bar to create, rename, duplicate or delete plans. The active plan is restored when you return.

Raise it in 3D

Switch to the 3D view at any time. Walls rise from the plan; you can orbit, zoom, and walk at eye level. Changes in 2D update the model live.

Keyboard shortcuts

The keyboard button in the top bar — or the `?` key — lists every shortcut, grouped by context: general, 2D plan, 3D view and walkthrough. The same list is available as a one-page printable sheet in your language. Pan is also a toolbar button on the plan and in 3D (same as holding Space), for anyone who does not use the shortcut.
