Understanding Floor Area Ratio

Understanding Floor Area Ratio (FAR) under ODA (Planning and Building Standards) Rules, 2020

Floor Area Ratio (FAR) is a crucial concept in urban planning and real estate development, governing the permissible ratio of built-up area to the plot size. In Odisha, the Planning and Building Standards are regulated by the Odisha Development Authority (ODA), which has recently updated its rules in 2020 to streamline development practices and ensure sustainable urban growth. This blog explores the intricacies of FAR under these updated regulations, highlighting its significance, calculation methods, and implications for developers and urban planners.

What is Floor Area Ratio (FAR)?

Floor Area Ratio (FAR), also known as Floor Space Index (FSI) or Floor Space Ratio (FSR), is a planning tool used to regulate the density of construction on a given plot of land. It is defined as the ratio of the total floor area of all buildings on a plot to the area of that plot. FAR determines how much area can be constructed upon a certain plot of land, balancing density with infrastructure capacities and environmental considerations.

Importance of FAR under ODA Rules, 2020:

1. Regulatory Framework:
   • The ODA Rules, 2020, provide guidelines on FAR to ensure orderly development, efficient land use, and infrastructure provision.
   • These rules are designed to promote sustainable development practices while accommodating the growing urban population.
2. Calculation Method:
   • FAR is calculated by dividing the total covered area (built-up area) on all floors of a building by the area of the plot on which it is constructed.
   • For example, if the FAR allowed is 2.0 and the plot size is 500 square meters, the total permissible built-up area would be 2.0 * 500 = 1000 square meters.
3. Types of FAR:
   • FAR can vary based on zoning regulations, land use categories, and infrastructure availability.
   • Higher FAR may be permissible in commercial areas to accommodate taller buildings and denser development, while residential areas may have lower FAR to maintain a balanced living environment.

Implications for Developers and Urban Planners:

1. Urban Density:
   • FAR directly influences urban density by determining how much floor area can be developed on a given plot.
   • Higher FAR encourages compact development, which can promote efficient land use and reduce urban sprawl.
2. Infrastructure Impact:
   • ODA Rules consider infrastructure capacities such as water supply, sewage systems, transportation networks, and environmental factors when setting FAR limits.
   • This ensures that development does not exceed the capacity of existing infrastructure, thereby maintaining service levels for residents.
3. Aesthetic and Environmental Considerations:
   • Higher FAR in residential areas helps maintain open spaces, ventilation, and sunlight access for buildings.
   • Design guidelines under ODA Rules, 2020, also emphasize sustainable building practices, energy efficiency, and aesthetic harmony with the surrounding environment.

Conclusion:

Understanding Floor Area Ratio (FAR) under the Odisha Development Authority’s Planning and Building Standards Rules, 2020, is essential for developers, urban planners, and stakeholders involved in real estate and infrastructure development. By adhering to FAR regulations, stakeholders contribute to sustainable urban growth, efficient land use, and enhanced quality of life for residents. The ODA’s updated rules aim to strike a balance between development aspirations and environmental stewardship, ensuring that cities like Odisha’s Bhubaneswar evolve responsibly while meeting the needs of their growing populations. For anyone engaged in property development or urban planning in Odisha, familiarity with FAR regulations is paramount to navigating the regulatory landscape effectively.
