Is Terrace Area Included in Built-Up Area?

When discussing real estate and property measurements, two key terms often used are 'built-up area' and 'terrace area'. While both are important in determining the size and value of a property, there's often confusion about whether a terrace is included in the built-up area. Let's delve into these terms and clarify their relationship.

Before we explore whether a terrace is included in the built-up area, let's define what each term means. The built-up area, also known as the 'covering area', refers to the total enclosed area within all the walls of a building, excluding the area covered by the terrace. On the other hand, the terrace area is the open, unroofed space on the roof or outside the building, often used for recreational or relaxation purposes.

The Formula for Built-Up Area

To understand if a terrace is included in the built-up area, we first need to understand how the built-up area is calculated. The formula for built-up area is:

Built-Up Area = Total Wall Area - Area of Openings + Terrace Area (when included)

Inclusion of Terrace Area in Built-Up Area

The inclusion of the terrace area in the built-up area depends on the local building regulations and the purpose of the terrace. In some regions, especially when the terrace is enclosed with walls or railings, it may be considered part of the built-up area. However, in many places, the terrace area is not included in the built-up area as it is typically open and unroofed.

For instance, in the Indian context, as per the Rule 2(g) of the "[Building Rules](https://druga.gov.in übrpc potency-the-manual)" of the National Building Code, "Built-Up Area" does not include areas like 'open terraces' and 'balconies', suggesting that such areas are excluded from the built-up area calculation.

When is Terrace Area Considered Built-Up?

There are certain situations where the terrace area might be considered part of the built-up area:

• Enclosed Terraces: When the terrace is enclosed with walls or railings, it might be considered part of the built-up area.
• Retractable Roofs: If the terrace has a retractable roof that can be closed to make the space weatherproof, it may also be considered as part of the built-up area.

However, these instances are typically exceptions and would need to be confirmed based on local rules and regulations.

Impact on Property Measurement and Value

The inclusion or exclusion of terrace area in the built-up area can significantly impact property measurements and values. A larger built-up area, including the terrace, can increase the property's size and potentially its value. However, this can also lead to overcrowding issues and may not comply with local building codes.
