How do I obtain the built-up area of a 3 storey inter-median house when I can get the land area but not the built-up area?

To obtain the built-up area of a 3-storey intermediate terrace house in Singapore, you need to consider several components:

Land Area and Plot Size

First, understand the land area and the minimum plot size requirements. For example, an intermediate terrace house typically has a minimum plot size, but this varies depending on the area and zoning regulations.

Floor Area

Calculate the floor area of each level of the house. This includes the living areas, bedrooms, kitchens, and any other usable spaces within the walls.

Wall Thickness and Common Areas

Add the thickness of the walls, including both internal and external walls. Typically, the built-up area is about 10-20% more than the carpet area due to the inclusion of wall thickness.

Balconies, Terraces, and Utility Areas

Include any exclusive balconies, terraces, or utility areas like dry balconies or outdoor spaces that are part of the property.

Staircases and Corridors

For a 3-storey house, you need to account for the space occupied by staircases and any internal corridors.

Formula

A simplified approach is to calculate the built-up area as follows:

• Start with the total floor area of all three levels.
• Add the thickness of the external walls.
• Include the area of any balconies, terraces, and utility areas.
• Add the space occupied by staircases and internal corridors.

For example, if each floor has a floor area of 150 sqm, and you add 10% for wall thickness and common areas, the built-up area for one floor would be approximately 165 sqm. For a 3-storey house, this would be 3 * 165 sqm = 495 sqm.
