Unlocking the Mystery of Built-Up Area: What It Encompasses in Property Calculations

by Godrej Properties Limited



Introduction to Built-Up Area

Internal Area

The built-up area includes the internal area of the property, which comprises the space within the walls. It encompasses the rooms, living areas, bedrooms, kitchen, bathrooms, and other internal spaces. The internal area is the living space and is considered as the primary component of the built-up area.

Walls and Structural Components

In property calculations, the built-up area takes into account the space occupied by walls and other structural components. This includes the thickness of the walls along the perimeter of the property, as well as any internal walls or partitions that separate different areas within the property. The inclusion of walls ensures that the total area enclosed by the external boundaries of the property is considered in the calculation.

Balconies, Terraces, and Open Space

Built-up area calculations also encompass the area of balconies, terraces, and open spaces attached to the property. These additional spaces, although not fully enclosed, contribute to the overall built-up area. Balconies and terraces are often included in the built-up area calculations, to provide a comprehensive understanding of the total usable space available to the occupants.

Common Areas and Shared Facilities

Another aspect covered in the built-up area is the proportionate share of common areas and shared facilities within a building or housing complex. Common areas such as corridors, lobbies, staircases, lifts, and other shared amenities are factored into the calculation. The inclusion of common areas ensures a fair allocation of space and accurately represents the total area utilised by all the occupants of the property.

Staircases and Shafts

Built-up area calculations also consider the space occupied by staircases, ducts, and shafts within the property. These elements, although not directly part of the livable space, are necessary components of the overall structure. Including staircases and shafts in the calculation ensures a comprehensive evaluation of the total area covered by the property.


Understanding the concept of built-up area is crucial for buyers to make informed decisions in real estate transactions. Built-up area calculations encompass the internal area of the property, including rooms, walls, and structural components. It also includes balconies, terraces, open spaces, common areas, shared facilities, staircases, and shafts. By considering all these elements, the built-up area provides a holistic representation of the total enclosed space within a property. Buyers should carefully review the specifications and floor plans provided by developers or sellers to understand the built-up area of a property and how it contributes to the overall living space.
