You’ve been dreaming about it for months, maybe even years. That old kitchen that never quite worked. The cramped bathroom with tiles from another era. Or just the feeling that your home doesn’t feel like you anymore. So, you’ve finally decided: it’s time to renovate.

Exciting? Definitely. Stressful? It can be. If you skip the crucial things to know before renovating a house in Singapore.

Most homeowners think renovation starts with picking paint or calling a contractor. But in Singapore, it starts with rules, permits, and careful planning. Miss a step, and you risk delays, blown budgets, or legal trouble.

Don’t worry, we’ve got you covered. In this guide, we’ll walk you through the key things to know before renovating a house in Singapore, so you can skip the stress and start building your dream home the smart way.

1. HDB Renovation Permits: Don’t Start Without One!

Before you grab a hammer, here’s the deal: you need HDB’s approval for most renovation works. This isn’t just a formality. It’s required by law, and skipping it can get you into serious trouble.

Here are the basics:

  • Apply for a renovation permit through your HDB-approved contractor.
  • You need a permit for things like:
        • Hacking walls or floors
    • Changing bathroom layout
    • Replacing windows or gates
  • No noisy work is allowed on Sundays or public holidays.
  • Renovation hours: 9 am–6 pm (weekdays), no work on Sundays/PH.

Make sure your contractor is HDB-licensed and follows all the rules.

2. Plan Your Renovation Budget Like a Pro

Thinking of giving your home a fresh new look? Whether you're moving into a brand-new unit or updating an older one, budgeting for your renovation is the second big step after the permit step.

Here’s a quick breakdown of average renovation costs in Singapore:

HDB Flats:

  • New HDB Flat: ~$45,000
     (Includes basic works like carpentry, flooring, painting, and electrical wiring)

  • Resale HDB Flat: ~$55,000
     (Usually higher due to hacking, plumbing updates, and redoing old structures)

Condominiums:

  • New Condo: ~$36,500
     (Typically needs less work – just built-ins, light fixtures, and styling)

  • Resale Condo: ~$62,500
     (More extensive – may involve wall modifications, custom carpentry, kitchen/bath upgrades)


Why the Price Difference?

Resale units often need more work, old tiles to hack, outdated layouts to fix, and worn fittings to replace. On the other hand, new units may already come with some essentials, which helps reduce costs.

What’s Included in the Budget?

Here's where your money usually goes:

  • Carpentry (wardrobes, kitchen cabinets, shelves)

  • Flooring (vinyl, tiles, or parquet)

  • Plumbing and electrical work

  • Painting and false ceilings

  • Lighting and fixtures

  • Appliances and fittings (for resale, especially)

Tip: Always set aside 10–15% extra for unexpected costs. Prices may vary based on your design preferences and material choices.

3. Singapore’s Interior Style Is Changing, And It’s Looking Good

Just a few years back, walking into a Singapore home felt like stepping into a Pinterest board with white walls, clean lines, and soft wood finishes. The Scandinavian minimalist trend was everywhere. It was simple, calm, and neat. But times have changed.

Now? Homes in Singapore are bursting with color, curves, and character. From soft pinks and bold blacks to deep greens and warm golds, homeowners are done playing it safe. The once “clean and minimal” aesthetic is making way for personalized, contemporary looks.

One of the coolest changes? Arched walls and doorways. Yup, they’re making a comeback in a big way. These rounded features soften up a room and instantly add style. And it’s not just about color. Singaporeans are embracing:

  • Textured walls

  • Statement lighting

  • Playful shapes

  • Mixed materials like rattan, glass, and metal

The result? Homes that feel fresh, modern, and unique. So if you’re planning a renovation, this is your sign to think beyond beige. Let your space reflect you. And remember: a splash of bold can go a long way!

4. Carpentry Can Make or Break Your Budget

In land-scarce Singapore, space is precious, and the smart way to use every inch of it is often through custom carpentry. Think kitchen cabinets that stretch to the ceiling, wardrobes fitted perfectly into corners, or sleek built-in storage that hides clutter beautifully.

Sounds amazing, right? But here’s the catch: it’s not cheap. Custom carpentry can easily take up 40% to 50% of your renovation budget, especially if you’re doing multiple rooms. That’s a huge chunk, and it adds up fast. Want a smart tip? Mix it up!

Instead of going full custom, consider blending built-ins with loose furniture. For example:

  • Built-in wardrobes for bedrooms, but freestanding side tables

  • Fixed kitchen cabinets, but movable shelves for storage

  • Custom TV consoles, but a standard coffee table

This way, you get the best of both worlds: functionality, flexibility, and cost savings. Custom carpentry is worth it where it counts. Just be strategic about where you spend, and you’ll keep both your space and your wallet happy.

5. Loose Furniture Looks Easy, But Timing Is Everything

One of the biggest things to know before renovating a house? Hold off on shopping for loose furniture and decor, no matter how good the sale looks.

We get it. That trendy chair is calling your name. And that coffee table? Half price today only! But here’s the thing: impulse buys can turn into big regrets if your renovation plans aren’t finalized.

Why? Because once your layout is locked in and measurements are clear, that “perfect piece” might turn out to be too big, too small, or just plain wrong for your space.

Singaporeans love a good deal, and who doesn’t? But if it can’t fit through your front door or clashes with your final design, it’s not a deal anymore.

Here’s a simple tip: Plan first. Shop later. Finalize your floor plans, double-check measurements, and wait until everything’s set. That way, your furniture fits your space, not the other way around. Your home will thank you.

6. Renovations Take Time And That’s Okay

Do you know the most important things to know before renovating a house in Singapore? It’s not going to be done in a week. If you’re working on a new BTO flat, expect around 8 weeks from start to finish. For resale flats, it may take even longer.

Why? Because good work takes time. Rushing leads to sloppy jobs, mistakes, and future repairs.

After the pandemic, delays are more common with materials, manpower, and even permits may take a bit longer. So, plan for the wait and trust the process. Take a breath. Your dream space is on the way.

Conclusion

Renovating a home is more than picking paint colors or tiles. It’s about making smart choices from the start. When you know what to expect, permits, timelines, and budgets all become less stressful.

These are the things to know before renovating a house in Singapore. And knowing them means fewer surprises and smoother work. Take your time. Plan well. Don’t rush. Your dream home is possible and with the right steps, you’ll get there without the headaches.
