StairCAD Pro: Custom Staircase Design and Calculation Software for Architects and Tradespeople

Welcome to StairCAD Pro, the leading application for designing, calculating the structure, and creating 2D/3D models of custom staircases. Designed for demanding architects, carpenters, masons, building engineers, and self-builders, StairCAD Pro transforms your site constraints into precise, internationally compliant construction plans.

🚀 WHY CHOOSE STAIRCAD PRO?
Calculating a staircase requires millimeter precision. A simple error in riser height or tread depth can make a structure uncomfortable, dangerous, or non-compliant with accessibility standards. StairCAD Pro automates all the architectural equations to guarantee reliable, aesthetically pleasing results that can be immediately used on-site.

📐 ALL TYPES OF STAIRS SUPPORTED
Straight Staircase: Single flight with precise adjustment of tread depth, nosing, and floor space.
Quarter-Turn Staircase: Management of 90° corner landings and automatic balancing for optimal climbing comfort.
Half-Turn Staircase (180°): Double flight with adjustable intermediate landing and overall space control.
Spiral/Helical Staircase: Automatic calculation of the stairwell, central column, and radius of the walking line.

⚙️ COMPLETE ANATOMY AND TECHNICAL PARAMETERS (A TO F)
StairCAD Pro breaks down your structure according to the official building standards:

A. Floor-to-floor height: Automatic adjustment of the number of risers.

B. Horizontal space: Total available floor space. C. Clear Clearance Width: Definition of the clear passage and guardrail.

D. Landing Platform and Intermediate Height: Precise alignment of flights.

E. Minimum Hopper Length: Automatic control of the clear clearance (minimum 2.00 m).

F. Step Details: Height (H) / Tread (G) ratio and strict verification of Blondel's Law (2H + G = 58 to 66 cm).

🏗️ STRUCTURAL MEASUREMENT AND MATERIAL ESTIMATION
Anticipate your costs and material orders with the integrated engineering module:

Reinforced Concrete: Automatic calculation of concrete volume in m³.
Formwork: Estimated formwork surface area in m².
Steel/Timber Structure: Developed length of structural stringers.
Total Weight: Estimation of the dead weight of the structure based on the selected material.
