Estimating HDB renovation costs: Key budget allocation metrics

Carpentry typically accounts for the largest portion of an HDB renovation budget, often ranging from 30% to 40%. This includes built-in wardrobes, kitchen cabinets, and custom shelving.

Flooring and tiling can take up 15% to 25% of your renovation budget, depending on the materials you choose and the size of the area to be covered. Opting for more premium materials will naturally increase this percentage.

Plumbing and electrical works usually constitute around 10% to 20% of the total budget. This covers essential services like wiring, lighting fixtures, and pipe adjustments.
