Floor area ratio (FAR) is a crucial concept in urban planning, defining the relationship between the total floor area of a building and the size of its lot. FAR is calculated by dividing the total floor area of a building by the area of the land on which it is situated. This ratio is used to control building density and ensure that buildings are of a proportional size to their surroundings. FAR is a vital tool for municipalities and planning commissions to regulate development and maintain the character of their communities.
Defining Floor Area Ratio (FAR)
Floor Area Ratio (FAR) is a crucial concept in urban planning and development. It measures the relationship between the total floor area of a building and the area of the land it sits on. Understanding FAR is essential for architects, developers, and city planners alike.
FAR Definition
Simply put, FAR is the ratio of a building’s total floor area to the area of its zoning lot. It indicates the intensity of land use and helps regulate building density within a given area.
Calculation
FAR is calculated using the following formula:
FAR = Total Floor Area / Lot Area
For example, if a building has a total floor area of 10,000 square meters and sits on a lot of 5,000 square meters, its FAR would be 2.0.
Benefits of Using FAR
FAR has several advantages for urban planning:
- Regulates Building Density: It ensures that buildings are not too densely packed, preserving open space and reducing congestion.
- Promotes Efficient Land Use: It encourages the construction of multiple-story buildings, making maximum use of limited land resources.
- Controls Traffic and Infrastructure Demand: Lower FARs reduce the demand for parking, utilities, and transportation infrastructure.
FAR Regulations
FARs are typically regulated by local governments through zoning ordinances. These ordinances specify maximum FARs for different zoning districts, ensuring a balance between development and livability.
FAR and Building Design
FAR can influence architectural decisions. A high FAR may encourage vertical development (e.g., skyscrapers) to maximize floor area within a limited lot size. A low FAR may lead to more horizontal development (e.g., single-family homes) to meet the allowable floor area.
FAR vs. Lot Coverage Ratio
FAR is sometimes confused with Lot Coverage Ratio (LCR), which measures the percentage of a lot that is covered by buildings. LCR helps regulate the amount of open space and landscaping on a property.
| Characteristic | FAR | LCR |
|---|---|---|
| Definition | Ratio of total floor area to lot area | Percentage of lot covered by buildings |
| Purpose | Regulate building density and intensity | Control open space and landscaping |
| Typical Values | 0.5 – 5.0 | 10% – 75% |
Question 1: What is floor area ratio?
Answer: Floor area ratio (FAR) is a planning regulation that determines the maximum amount of floor space that can be built on a given plot of land.
Question 2: How is floor area ratio calculated?
Answer: FAR is calculated by dividing the total floor area of a building by the area of the land on which it is built.
Question 3: What are the factors that affect floor area ratio?
Answer: Factors affecting FAR include local zoning regulations, building height restrictions, and the shape and size of the land parcel.
And that’s a wrap on floor area ratio! I know, it’s not the most exciting topic, but hey, knowledge is never a bad thing, right?
