Features

A real floor-plan editor, minus the manual

Planaira fits in a tab and covers the whole journey — home, shop or office — from the first wall to the PDF you send your contractor.

2D drawing

Walls to the centimeter

The Room tool traces a full rectangle in one drag; the Wall tool goes point by point for L-shapes, T-shapes, angles. At any moment, type an exact length on the keyboard.

  • Keyboard input: “452” then Enter
  • Snapping to existing walls and corners
  • Areas and perimeters computed continuously
Catalog

Doors, windows, furniture: drag and drop

A side catalog in seven families: rooms, joinery, structure, furniture, garden, boundaries, plot. Every item sits on a wall or on the ground and adjusts in real dimensions — and search still finds a tile under a synonym or a typo.

  • Twenty-three dimensioned joinery types: door, front door, double door, sliding and pocket doors, garage door, shop door, window, french door, glass wall, fixed, ribbon, basement, round and arched windows, oculus, slit window, Crittall partition, arched opening, opening, bar, skylight, dormer
  • Structure: straight, quarter-turn, half-turn and spiral stairs, ramp, loft ladder, elevator, stairwell void, columns
  • Full furniture set: living room, bedroom, kitchen, bathroom, office, laundry
  • Garden & plot: trees, hedges, fences, gate, pool, jacuzzi, deck, shed
3D view

Seven viewpoints, zero “generate” button

The 3D follows every stroke. Top, front, side, isometric, perspective, eye level — and the 1.10 m wall cut to inspect the inside from above, tops in violet.

  • Orbit: drag to rotate, wheel to zoom
  • Eye level: WASD to walk, Shift to run
  • Doors and windows that open, roofs you can show, levels you can stack
  • Twenty-three 3D display styles: model, clay, blueprint, sketch, lego, neon, winter, glass…
AI renders

A photo of your space, realistic or stylised

Place the 3D view, pick a style, hit generate: AI turns the volume you drew into an image. Interior room by room, exterior whole building — the 3D depth map guides the render, so the walls, openings and proportions are the ones on your plan.

  • Nine interior moods: photorealistic, warm, Scandinavian, high-end, modern, industrial, bohemian, evening, sketch
  • Five exterior views: façade, on the street, on the plot, garden, aerial
  • As many variants as you like, a history of recent renders, image download
PDF export

The file your contractor expects

A dimensioned plan to scale, a surface table per room and per level, a joinery table with numbered markers repeated on the plan. Trade terms are defined in a footnote.

  • Markers ①② identical on plan and table
  • Column headers repeated on every page
  • Multi-level: one plan per floor
