1. Ground Coverage in Delhi - TronHomes Insight:
Definition: It refers to the portion of your plot that can be covered by the building, measured at ground level within the structural walls/columns/slabs. It excludes projections like balconies, canopies, and porches that are free from Floor Area Ratio (FAR) calculations.
Essentially, ground coverage is the area of ground your building occupies on your plot.
2.FAR in Delhi - Simplified by TronHomes:
Definition: FAR, or Floor Area Ratio, is the ratio of the total covered area on all floors to the plot area.
Practical Tool: TronHomes provides a user-friendly FAR Calculator for Delhi. Enter your plot details and instantly understand your building potential.
Example: On a 251 sqm plot with an FAR of 300, you can build up to 753 sqm in total across various floors.
Exclusions in FAR and Ground Coverage Calculations:
TronHomes also highlights the aspects that are not included in FAR and ground coverage calculations, like lift machine rooms, swimming pools, open ramps, fire staircases, and others.
FAR & Ground Coverage as Per MPD 2021: TronHomes provides a detailed table explaining the maximum ground coverage, FAR, and number of dwelling units for different plot sizes.
3. Setback in Delhi - TronHomes Explanation:
At Tron Homes, we understand that navigating the regulations around setbacks in Delhi can be complex, but it's a crucial aspect of urban planning and construction. Here's a simplified explanation tailored to our understanding at Tron Homes:
What is a Plot Setback?
A setback is the space on your plot reserved for light, ventilation, and essential services like connectivity to municipal drains. It's the area between your plot boundary and the building that you plan to construct. These setbacks ensure that buildings have enough open space around them for various utilities and also help maintain the aesthetic appeal of the neighbourhood.
Set Back Line Explained:
This is a line, usually parallel to the plot boundaries or the centerline of a road, defined by the Authority or as per the Master/Zonal Plan recommendations. No construction can occur beyond this line towards the plot boundaries, except with special permission from the Authority.
Minimum Setback Requirements in Delhi:
Delhi's building bye-laws stipulate minimum setbacks based on plot size. These requirements are essential for ensuring that each property has adequate open space for light and ventilation. For example, a smaller plot might have lesser setback requirements compared to a larger plot.
- For plots below 100 sq.m., different setback rules apply.
- As the plot size increases, so do the setback requirements on all sides of the plot.
The minimum setback in Delhi building bye laws is given in the table below:
Plot Size (in square metre) | Front | Rare | Side1 | Side2 |
Below 100 | 0 | 0 | 0 | 0 |
Above 100 and upto 250 | 3 | 0 | 0 | 0 |
Above 250 and upto 500 | 3 | 3 | 3 | 0 |
Above 500 and upto 2000 | 6 | 3 | 3 | 3 |
Above 2000 and upto 10000 | 9 | 6 | 6 | 6 |
Above 10000 | 15 | 9 | 9 | 9 |
At Tron Homes, we prioritise making these complex regulations more understandable and manageable for our clients. By considering these setback guidelines, you can effectively plan the construction of your property in Delhi, ensuring compliance with local regulations and optimising the use of your plot.

3. Stair Coverings (Mumty): A Mumty covering the stairs, not exceeding 3 metres in height, is exempt from being included in the building's height.
4. Chimneys and Parapet Walls: Chimneys and parapet walls are excluded from height calculations provided they don't surpass 1.5 metres in height.
5. Screen Walls: These walls can be built up to a height of 1.8 metres without being included in the building's total height.
6. Solar Panels: Solar panels can be installed at any height, including ground level, terraces, or rooftops, without affecting the height calculation of the building.
7. Lifts: The height of car lifts or passenger lifts, including the machine room that accesses the rooftop or terrace, is not counted towards the building's total height.
