Wooden Staircase Dimensional Diagram Concept Explanation
The image illustrates a technical design and spatial layout for a custom-built, u-shaped wooden staircase. It serves as a visual guide for architects and carpenters, detailing how the structure integrates into a corner space while maintaining specific ergonomic standards. The diagram emphasizes the relationship between the physical footprint of the stairs and the vertical clearance required to connect two floor levels.
Key Components & Features Total Height (Rise): The vertical distance from the floor to the upper landing is marked at 2.8 m, establishing the total elevation the staircase must cover.
Winder Tread Section: A central transition area where the stairs turn 180 degrees. This section uses angled treads rather than a flat landing to save horizontal space.
Tread Dimensions: Individual step heights (risers) are specified at 0.2 m, ensuring a consistent climbing rhythm.
Total Run and Width: The horizontal projection is broken down into segments, including a 2.7 m upper length and a 1.6 m lower base length, with a standard stair width of 0.8 m to 0.9 m.
Structural Support: The design features an open-riser aesthetic with a notched stringer system, providing a modern, airy look while maintaining structural integrity.
Design Summary This technical illustration provides a comprehensive blueprint for a space-efficient staircase. By utilizing a winder design and precise 0.2 m risers, the system balances vertical accessibility with a compact horizontal footprint. The clear labeling of lengths and widths allows for accurate material estimation and ensures the final installation fits perfectly within the designated 2.8 m by 2.7 m corner envelope.
