Here’s a comprehensive guide on how to calculate plinth area rate:

Understanding the Plinth Area:

  • Definition: The plinth area, also known as the built-up area, is the total covered area of a building’s floor at any given level, including the external and internal walls, but excluding open spaces like balconies, voids, or staircases.
  • Importance: It’s used for various purposes, including estimating construction costs, calculating property taxes, and determining floor area ratio (FAR) compliance.

Calculating Plinth Area Rate:

  1. Measure Dimensions:
    • Measure the external length and breadth (width) of the building at the floor level you want to calculate.
  2. Calculate Plinth Area:
    • Multiply the length and breadth: Plinth Area = Length × Breadth
  3. Obtain Plinth Area Rate:
    • The plinth area rate is usually expressed in terms of currency per square meter (e.g., Rs. 1200/m²).
    • It varies based on location, construction quality, and market trends.
    • Consult a local architect, builder, or municipal authority for the current plinth area rate in your area.

Example:

  • If the plinth area of a building is 100 sq.m and the plinth area rate is Rs. 1200/m², the estimated construction cost based on plinth area would be: 100 m² × Rs. 1200/m² = Rs. 120,000

Key Points:

  • Exclusions: Open spaces like balconies, porches, terraces, voids, and staircases are not included in the plinth area calculation.
  • Local Variations: The exact definition and calculation method may vary slightly depending on local building regulations and practices.

Additional Information:

  • Plinth Area Method: This method is commonly used for preliminary cost estimation in construction projects.
  • Factors Affecting Rate: The plinth area rate is influenced by factors like location, type of construction, quality of materials, and current market trends.

Always consult with qualified professionals for accurate cost estimations and compliance with local building regulations.
