Renovation cost in Singapore (2026): HDB, resale and condo budgets
Renovation cost in Singapore for 2026: published ranges for BTO and resale HDB flats, what drives the price, and how to compare contractor and ID quotes.
Updated 2 min read
Your renovation cost in Singapore depends on the flat type, whether it's new or resale, and how much you change. Here are the ranges published for 2026, what moves the number, and how to compare quotes.
Typical budgets in 2026
Published guides and renovation-platform project data mostly fall in these ranges for a 4-room HDB flat:
| Scope | Typical published range |
|---|---|
| Resale 4-room, standard renovation | about S$55,000 to S$95,000 |
| Designer-led renovation (BTO or resale) | about S$80,000 to S$140,000 |
These come from several guides and project datasets and differ by source. They usually exclude furniture, appliances and moving. Your quote depends on your design and the condition of the flat.
What drives the price
- New or resale: resale flats often need hacking, rewiring and new finishes before any new work starts.
- Carpentry: wardrobes, kitchen cabinets and feature walls are often the biggest line items.
- Wet works: new tiles, re-screeding floors and bathroom redos.
- Electrical: rewiring and new points.
- Design and project management: an interior designer's fee is built into the quote.
Comparing quotes like for like
- Give every firm the same floor plan and brief.
- Ask for an itemised quote: carpentry by foot run, flooring by square foot, and so on.
- Check materials and brands: laminates, hinges, tiles and paint.
- Check the payment schedule: avoid paying most of it up front.
- For HDB flats, confirm the contractor is on HDB's Directory of Renovation Contractors. Our HDB renovation permit guide explains the rules.
Plan the rest of the move-in
Renovation is one part of moving in. After it, you'll need a post-renovation clean, curtains or blinds and movers.

Frequently asked questions
How much does it cost to renovate a 4-room resale HDB flat?
2026 guides and project data mostly put a 4-room resale renovation at about S$55,000 to S$95,000, with designer-led projects higher. Resale flats usually cost more than BTOs because of hacking, rewiring and replacing old finishes.
Is a BTO renovation cheaper?
Usually, yes. New flats need less demolition and replacement, so similar designs typically cost less than in a resale flat.
Interior designer or contractor?
An interior designer plans the design and manages the trades, which costs more but saves you coordination. A contractor is often cheaper if you know what you want. For HDB flats, the contractor must be on HDB's Directory of Renovation Contractors.
Do renovation quotes include furniture and appliances?
Usually not. Most renovation estimates cover works like carpentry, flooring, electrical and painting, and exclude loose furniture, appliances and moving.
