Understanding Plot Sizes
Unlock Audio Lesson
Let's start with the minimum plot sizes required for different residential buildings. Can anyone tell me what a detached building's minimum plot size is?
Isn't it above 250 square meters?
Correct! A detached building must have a minimum plot size of over 250 m². Now, can someone explain the minimum sizes for semi-detached and row-type buildings?
Semi-detached needs 125 to 250 square meters, and row-type is from 50 to 125 square meters.
Great! Remembering these sizes can be made simpler with the acronym 'DRS' for Detached, semi-detached, and Row-type. What's the significance of these sizes in building planning?
They ensure adequate space for each type of house, right?
Exactly! Adequate space enhances comfort and functionality.
Frontages and Open Spaces
Unlock Audio Lesson
Now, let’s talk about building frontages. What do we know about the minimum frontage for different residential plots?
For any street, it’s a minimum of 6 meters, but for row housing, it's 5.5 meters.
Correct! Minimum frontages are crucial for accessibility and aesthetics. Can anyone tell me what the front open space requirement is based on street width?
If the street width is up to 7.5 meters, the open space should be 1.5 meters.
Well done! This approach ensures enough light and air flow, which contributes to healthy living conditions. Let’s memorize this with ‘7.5m + 1.5m’ for the initial requirement.
That’s helpful!
Plinth Areas and Regulations
Unlock Audio Lesson
Next up, let’s discuss permissible plinth areas. Who can summarize the maximum permissible covered area by the plot size?
For plots less than 200 m², it’s 66.66% of the plot area.
Spot on! And what about larger plots?
For plots between 201 and 500 m², it’s 50%.
Correct! And how does this relate to building heights?
The maximum height is determined by the width of the abutting road plus front open space!
Exactly! Remembering the relationship between plot area and height can help visualize building planning.
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
The section elaborates on the required minimum plot sizes and front open spaces for various types of residential buildings. It details classifications for detached, semi-detached, and row-type buildings, as well as regulations for open space concerning various street widths.
Detailed
In this section, we explore the critical guidelines regarding minimum plot sizes and building frontages essential for residential structures. The principles outlined are governed by the classification of buildings which include detached, semi-detached, and row-type buildings with respective requirements for plot sizes ranging from above 250 m² for detached buildings to 50-125 m² for row-type buildings. Frontages must also meet specific standards, with minimum requirements ranging from 6 meters to 5.5 meters for row housing. Additionally, the section covers necessary spatial regulations such as minimum front open space based on street width and permitted plinth areas relative to the size of the plot. These guidelines are vital as they ensure proper planning and adherence to building codes, promoting sustainability and comfort in residential development.

Different types of residential Building, plot size and their frontages
Types of Residential
| Building | Plot size in m² | Frontage in m |
|---|---|---|
| Detached Building | Above 250 | Above 12 |
| Semi Detached Building | 125-250 | 8-12 |
| Row type Building | 50-125 | 4.5-8 |
Note: Minimum frontage on any street 6m, for row housing it may be 5.5m
Detailed Explanation
This chunk outlines the different types of residential buildings based on their plot size and required frontage. Each building type is categorized with specific dimensions for the plot size in square meters and the minimum width of the front-facing area (frontage) that faces the street. Detached buildings require larger plots and frontages compared to semi-detached and row-type buildings, which are suitable for denser housing configurations.
Examples & Analogies
Think of a neighborhood where large single-family homes (detached buildings) need more space between them and the street compared to townhomes (row-type buildings). This helps provide a spacious appearance for larger homes while allowing row houses to fit more units in a smaller area.
Minimum Front Open Space

Minimum Front open space to be provided
| Width of street in front of plot in m | Front open space minimum in m |
|---|---|
| Up to 7.5m | 1.5 |
| 7.5 to 18 | 3.0 |
| 18 to 30 | 4.5 |
| Above 30 | 6.0 |
Detailed Explanation
This chunk presents regulations for the minimum open space in front of a building based on the width of the street. It indicates that narrower streets require less front open space, and as street width increases, so does the necessary open space. This regulation ensures that buildings are set back appropriately from the street, allowing for light, air, and aesthetic spacing between the road and the structure.
Examples & Analogies
Imagine a wide avenue with several tall buildings set back far from the sidewalk. This space allows for landscaping and trees, creating a pleasant atmosphere. Conversely, in narrower streets, homes are closer to the road, which is why less space is mandated in front of those buildings.
Permissible Plinth Area

Permissible Plinth Area (Covered area) in Residential Plots
| Area of Plot | Max. Permissible covered area |
|---|---|
| < 200 m² | 66.66% of plot area |
| 201 to 500 m² | 50% of the plot area |
| 501 to 1000 m² | 40% of the plot area |
| > 1000 m² | 33.33% of the plot area |
Detailed Explanation
In this chunk, we discuss the allowed maximum coverage area, or plinth area, of buildings on residential plots. The percentage of the total plot that can be built upon decreases as the size of the plot increases. Smaller plots can have a larger proportion of their area covered, while larger plots are restricted to a smaller coverage to preserve open spaces and manage density.
Examples & Analogies
Consider a small house on a small lot where nearly all of it can be built upon. In contrast, a large estate might require a substantial garden or yard space, so builders have less percentage of coverage allowable. This helps maintain the character and feel of neighborhoods.
Open Space Requirements

Minimum Rear open space to be provided (up to 10m height): Average width = 3m but not less than 1.8m
Minimum side open space to be provided (up to 10m height)
- Detached building: 3m on both sides
- Semidetached building: 3m on one side only
Detailed Explanation
This segment outlines the requirements for open spaces around residential buildings. For rear and side spaces, specific minimum widths are defined to ensure accessibility, light, and ventilation. Detached buildings need more open space around them compared to semi-detached buildings, which are designed to share walls and thus require less side space.
Examples & Analogies
Think of two different homes: a standalone cottage that needs open land around it for light and air, and a duplex that is attached to another house. The duplex can afford to have less space on one side since it shares a wall, whereas the cottage needs room on all sides to feel open and welcoming.
Floor Area Ratio

Floor Area Ratio:
- Floor area ratio (FAR) = Total covered area of all floors / plot area
- FAR : 1 to 2 depending on type of construction
- Maximum building height = (1.5 x width of abutting road) + front open space
Detailed Explanation
This final chunk discusses the Floor Area Ratio (FAR), a critical factor in urban planning that dictates how much area can be built upon relative to the size of the plot. A FAR of 1 means that the total building area is equal to the plot area, while a FAR of 2 means you can build twice the plot area, including multiple floors. This ratio helps control building density and is influenced by the width of the adjacent road.
Examples & Analogies
Imagine an empty lot. If the building code allows a FAR of 1, you can build one floor that takes up the entire lot. But if you have a FAR of 2, you could build two stories on the same footprint. This is similar to stacking books: one book per shelf (FAR 1) or two books on each shelf (FAR 2). The roadway width determines how high your bookshelves can go.
