3D Configurator
Set the rise, going and width in millimetres. Watch the staircase build itself in 3D, price itself as you go, and check its own dimensions against UK Part K.

Imperial defaults on a product built in metric
Millimetres end to end — cm, m or inches on demand
Configurators that dead-end at “request a callback”
A price panel that updates with every option change
Building-regs problems surface only after manual review
Instant UK Part K checks as dimensions are entered
Design tools that fall apart on a phone
One responsive layout, from 375 px to ultrawide
What StairSpec is
Nothing is a pre-made model. Every tread, string and spindle is generated from your dimensions, so any size is buildable.
Base rates, timber multipliers and option adders live in one editable rules file — change costs without touching logic.
Rise, going, pitch and 2R+G are validated against Approved Document K the moment a dimension moves.
Pine, White Oak, Ash, Axxys and Fusion, each with its own grain, roughness and finish in the viewport.
Design one now — no sign-up.
The configurator runs entirely in your browser.
