Coarse Plot with Schematic Drawing :
A Coarse Plot Drawing (also called a Preliminary or Concept Plot Layout) is the very first draft of how your land (plot) will be developed — before making detailed architectural or structural plans.
It’s called “coarse” because it shows only the major components — not exact wall thicknesses or finishes.
It combines:
- The plot layout (land area with boundaries, road, setbacks)
- A basic schematic drawing (building position, orientation, and room zones)
🎯 2. Purpose of a Coarse Plot + Schematic Drawing
Objective Description Site Utilization Shows how much of the plot will be used for building vs. open space. Orientation & Vastu Alignment Helps ensure the structure faces the correct direction (East/North).Approval Readiness Early draft for discussions before formal submission to the local authority (e.g., Chennai Corporation / CMDA).Design Planning Decides the best location for rooms, parking, and service areas before final design. Client & Architect Coordination Quick visual to discuss requirements.
