an architectural concept poster for a modern staircase design, presented as a combination of 3D renderings and technical diagrams. The style is inspired by minimalist industrial design, featuring a mix of wood and concrete.
Below is a detailed breakdown of the image’s components:
1. VISUAL COMPOSITION AND MATERIALS
The poster uses an isometric 3D view as the central focus, surrounded by technical callouts.
• Materials: The stairs utilize wood parquet for the treads (steps) and landing. The handrail is a matching wood with a "Borneo Finish" and "Gloss Polish." The structural walls are rendered as unfinished concrete, providing a "brutalist" contrast to the warm wood.
• Handrails: Slim, minimalist wooden handrails are supported by thin metal posts, creating an open, airy feel.
2. TECHNICAL DIAGRAMS (SECTIONS)
The image provides several detailed "sections" (cut-through views) to explain the construction:
• Handrail Section: Located at the top, showing the profile of the wooden rail. It indicates a "minimum 5 cm" clearance and a specific "connection to steel base."
• Step Section (Potongan): A close-up detail in the bottom left shows the "nose" of the stair step. It specifies a 20 mm thickness for the wood parquet and a 40 mm overhang.
• Stair Step Section: An elevation view on the bottom right showing the vertical profile. It marks the total floor-to-floor height as "A" and the handrail height at 100 cm.
3. MATHEMATICAL FORMULAS
The poster includes architectural formulas used to calculate ergonomic stair dimensions (though some text contains "AI-generated" artifacts or slight inconsistencies):
• Blondel’s Rule (Approximation): The text refers to the classic ergonomic formula where (the average human stride).
• Variables: * H = Stair Tread (depth)
• a = Riser Height
• N = Number of Steps
• A = Floor-to-floor Height
4. LAYOUT AND NOTATIONS
• Plan View: The bottom left features a top-down view (plan) of the landing, showing the direction of travel and dimensions like and , which represent elevation levels.
• Landing Detail: The central 3D view highlights a 180-degree turn landing, which is essential for saving space in multi-story designs.
• Covering: A note points out that the underside or sides of the stairs use a "Multiplex Finish" with "White Duco" (a type of automotive-grade paint often used in high-end cabinetry).
