1. Average Renovation Costs in 2025

In 2025, the average cost to renovate a 5-room HDB flat in Singapore ranges from SGD 45,000 for basic updates to SGD 85,000 for a more premium makeover. The final price depends on the type of materials used, extent of work (e.g., hacking, tiling, carpentry), and the interior designer or contractor you hire. BTO flats generally cost less to renovate compared to resale units, which often need more intensive work like rewiring or waterproofing. Homeowners should also consider market trends and rising material/labour costs when budgeting.

2. Cost Breakdown by Renovation Area

Here's a rough breakdown of where your renovation dollars go: kitchen (SGD 12,000–20,000), bathroom (SGD 6,000–10,000 per unit), living room (SGD 8,000–15,000), and bedrooms (SGD 5,000–10,000 each). Custom carpentry, such as built-in wardrobes or kitchen cabinets, can significantly push up your cost. If you’re planning to install air-conditioning, rewiring, or smart home systems, factor in another SGD 5,000–10,000. Budgeting by room helps you prioritise what's essential versus optional.

3. BTO vs Resale: Renovation Needs

BTO (Build-To-Order) flats are typically delivered in a bare or semi-finished state, making them easier and cheaper to customise. In contrast, resale HDBs may come with old fittings, flooring, or layouts that don't suit modern lifestyles. Renovating a resale flat might involve hacking, new piping, or reconfiguring room layouts, adding thousands to the cost. While resale units offer more space, homeowners need to factor in higher renovation costs and possible HDB renovation restrictions.

4. Ways to Save on Your Renovation

To stay within budget, consider working with an interior designer who offers renovation packages. These often bundle essential services like design, project management, and basic works at a more affordable rate. Opt for laminate over solid wood, vinyl instead of tiles, and modular furniture over custom carpentry where possible. It also helps to plan your renovation in phases — prioritise key areas like bathrooms and kitchen first, and update the rest over time. Lastly, always get multiple quotes to avoid overpaying.
