🏙 High-Density Office Block Generator for Grasshopper

A Grasshopper-based parametric tool for automated generation of high-density office building layouts across multiple plot scales. The generator automatically detects plot geometry and applies context-sensitive patterns, allowing designers to customize layouts through a wide range of planning and morphological parameters.

✨ Key Features

✅ Automatic Office Layout Generation

• Supports multiple plot scales (1–4 ha, 4–9 ha, and large composite plots)
• Includes multiple street/block patterns for each scale

✅ Parametric Control

• Planning Indicator:
  
  • Floor area ratio
  • Building Density
• Morphological Controls:
  
  • Secondary subdivision
  • Building typology
  • Building depth/width/Height Control

✅ Adaptive Logic

• Automatically detects plot geometry
• Generates context-sensitive patterns based on open space and buildable area distribution

📦 Plugin Components

The plugin includes three main Grasshopper clusters:

1. Small-Scale Block Generator

   • Plot size: 1–4 hectares
     
   • Includes 3 block pattern options > Small-Scale Block Generator

2. Medium-Scale Block Generator

   • Plot size: 4–9 hectares
     
   • Includes 3 block pattern options > Medium-Scale Block Generator

3. Large-Scale Composite Generator

   • Combines small plots into larger ones (3×2 arrangement)
     
   • Adapts to open space and buildable area for 2 pattern options > Large-Scale Composite Generator

🛠 How to Use

1. Download and unzip the repository
   
2. Open Grasshopper in Rhino 8
   
3. Load the corresponding Office Block Generator.gh definition
   
4. Input your plot boundary curve by defining Set-edge points
   
5. Adjust grid size(x,y) by sliders to generate and customize building layouts in real time
