Stairwright – Staircase Generator for Blender

Straight, L, U, spiral and floating stairs with railings

See all my Blender addons >

Staircase Generator builds complete, photoreal staircases inside Blender: treads, risers, stringers, landings, balusters, newel posts and handrails, all in one clean mesh with real PBR materials. Pick one of 48 designs, from a classic oak hall stair with turned spindles to a floating walnut stair with LED strips, a steel spiral, a sweeping marble curve or an imperial staircase for a palace, then change anything and watch it rebuild live.

Every common plan is covered: straight flights with or without a mid landing, L stairs with a quarter landing or winders, U stairs with a half landing or winders, three flights around an open well, spiral stairs on a centre column, curved helical stairs, imperial and bifurcated stairs that split at the landing, and steep alternating-tread loft stairs. Set the floor height and the number of risers, and the stair keeps every step equal, with comfort notes when it gets too steep.

Choose what carries the steps: closed or cut stringers, a central steel spine, cast concrete, solid blocks, folded steel plate, treads floating out of the wall, or treads hung from the ceiling on steel rods. Railings come as spindles and newels, posts and rail, frameless glass in a shoe, glass between posts or on standoffs, stainless cables, flat bars or solid panels, with seven baluster and six handrail shapes.

One click, a new staircase

Surprise builds a random staircase from the 48 designs: new plan, size, railing and finish every time.

Questions

Which Blender versions are supported?

Blender 4.2 and newer. It is tested on Blender 4.2, 4.5 and 5.2 LTS.

Can I set an exact floor-to-floor height?

Yes. Enter the height and the number of risers; every step gets the same rise, and the sidebar shows the rise, the going and the pitch, with a note when the stair is too steep.

Can I use the stairs in a game engine?

Yes. Each staircase is one mesh with image-based PBR materials. Pick Low detail for fewer faces, then use Convert to Mesh and export as FBX or glTF.

If I duplicate a staircase, does editing one change the other?

No. Every staircase keeps its own settings, mesh and materials, also after Shift+D or Alt+D.
