Stairs Maker Add-On appears in the superhive library at rank 244. It stands out for handling both stairs and railings through one panel while keeping the underlying Geometry Nodes work out of the user's way.
Stairs Maker Add-On is a Blender add-on for creating stairs with railings and a wide set of customizable options. Once enabled, it adds a panel to the 3D Viewport side panel, where a single button turns any selected object into a stairs or railings object. Under the hood it applies a Geometry Nodes modifier, but every control the user needs sits in that side panel, organized inside dropdown menus, so no Geometry Nodes experience is required.
A stairs object is built from three elements — Construction, Treads and Risers — while railings use four: Posts, Handrail, and Vertical and Horizontal bars. All are editable in size, form and UV-mapped material, and any stairs object can be deformed along a curve. UV mapping is controlled by a vector attribute that converts into a real UV map when geometry is applied, editable in the UV editor and usable when exporting to other 3D software.
Recent updates add 32 interactive gizmos for adjusting the staircase in the viewport, six default presets plus up to eight custom slots, tapered staircases, handrail swirl, and randomization and zig-zag offsets for posts, handrail and vertical bars. A free user manual and video tutorials are available.
Stairs Maker Add-On is best for blender users who need to create customizable stairs and railings.
Stairs Maker Add-On is completely free to download and use.
Stairs Maker Add-On has been updated across many Blender releases, with early builds targeting Blender 3.3 and 3.4, then 3.5, 3.6, 4.0, 4.1 and 4.2, up to the 3.4.4 release for Blender 4.4. From Blender 3.6 onward there is no longer any need to keep the Geometry Nodes modifier active. For the exact build that matches your Blender version, check the developer's page.
Stairs Maker Add-On applies a Geometry Nodes modifier to the object you select, but you do not need any Geometry Nodes experience to use it. Everything that matters for the user happens in the side panel of the 3D Viewport, where a button creates the stairs or railings and the resulting options are organized inside dropdown menus. You adjust sizes, forms, materials and other settings there rather than editing node trees directly.
Stairs Maker Add-On maps all of its geometry using a vector attribute that controls the UV layout. When you apply the geometry, that attribute is converted into a real UV map, which you can edit in the UV editor like any other UV map. This same map is used when you export the geometry into other 3D software, so the stairs and railings keep their UV mapping outside Blender.
Stairs Maker Add-On includes a gizmo editing system with 32 interactive gizmos, letting you adjust the staircase directly in the 3D Viewport using visual controls. Its presets system offers six default presets and support for up to eight custom presets, so you can save and reload staircase and railing styles. These arrived in the 3.4.4 release for Blender 4.4, alongside tapered staircases, handrail swirl and randomization options.
Stairs Maker Add-On is listed as free in this catalog. Pricing and licensing terms can change over time, so for the current details it's best to check the developer's page on superhive. The add-on also comes with a free downloadable user manual that explains every option in detail, plus video tutorials covering the basics and a newer video on FAQs and updates.
