See what makes our stair design software
the popular choice…

  • Versatility

    Build spiral stairs, straight flights, turning stairs with winders, curved stairs, central cut string stairs and more. Perfect for wood, metal or stone stair building. Special functions are included for drawing stair parts (wood or marble) covering concrete stairs.

  • Speed

    Our stair program enables you to quickly input stair dimensions and then automatically calculates the stairs to standard building regulations.

  • Easy and Safe

    StairDesigner uses special algorithms to calculate and optimise stringers and step shapes and positions. This makes turning stairs with winders easy and safe to do. Build stairs with cut strings, boxed strings, straight, curved and wreathed.

  • Automation

    Automatically calculates all stair parts: strings, steps, risers, newel posts, spindles and hand rails. Print plans, parts and cutting lists in a workshop folder. Print full size part templates as workshop mark ups for cutting and machining. Export post processor files for CAD/CAM programs and CNC routers.

  • Great Presentation

    Builds real 3D models with wood textures and lighting and transparency.

  • Time and Money Saver

    Easy to learn and even easier to use. Cuts out design and mark up errors and avoids unnecessary work throughout the construction process.

Intuitive Workflow That Mirrors Real Life

  • Stairwells & Flights

    Calculates spiral and helicoidal stairs. Up to 7 flights per stair. Each flight can have its own length and width. Variable angles for first and last steps. Variable angles between each flight.

  • Auto Calculations & Verifications

    Calculates step height, going and tread line. Verifies the 3 parameters H, G, and tread line, with min and max values. Quick wizard function optimises the number of steps and flight lengths. Automatic and optimised dividing of balusters for closed and cut strings.

  • Balancing Function

    Automatic step balancing function gives optimized steps and stringers. Fully parametric balancing function works on groups, fix steps, works on any shape staircases.

  • S Shaped Stairs

    Draw any shaped stair with up to 7 flights at any angle, any turn, each with its own specifications. Draw S shaped stairs, L shaped stairs, U shaped stairs, any shaped stairs.

  • Steps & Risers

    Move and rotate any step individually. All assembly details are parametric, thickness, overlaps, recesses, etc.

  • Strings, Newel Posts & Handrails

    Fully parametric straight, curved, wreathed, closed or cut strings. Parametric newel posts, handrails and balusters.

StairDesigner in Action

1. Calculate and draw a quarter turn stair with winders

On site dimensions are input into StairDesigner. The program calculates the stairs, optimizes the number of steps, the step height and going and draws the plan.


Design time: around 30 mins

2. Building a 3D model and printing out different 3D views

StairDesigner automatically builds the 3D model. You can view the model in all its details to verify the design and export different views for commercial documentation.

Time to build the 3D model: 0 mins

3. Workshop drawings and folder

Once the plans are drawn up StairDesigner automatically creates a workshop folder with a plan drawing and separate drawing for each stair part.

Time to print workshop folder: 5 to 10 mins

4. Workshop templates

Our stair designer software also outputs the full size workshop templates, DXF files for CAD/CAM and CNC machining (and brand specific post processor files for Homag, SCM, Morbidelli, Biesse, Felder, Vitap, Brema, Holz-her etc).

5. Cutting lists

StairDesigner automatically prints out the cutting lists with dimensions of each part, total weight and price of the raw materials, and total volume of wood used.

Time to print cutting lists: 1 min

6. The finished stair

An incredibly efficient way to design and build.

As well as wooden staircase construction plans, perfect for concrete and metal stairs, and all types of stairwells: U-shaped; L-shaped; curved; spiral; or anything in between.
