2. Understanding Renovation Costs in Singapore
The cost of home renovation in Singapore varies significantly depending on the type and size of the property. For instance, new HDB BTO flats can be renovated for SGD 20,000 to 70,000, while the full renovation of resale condos might cost between SGD 60,000 to more than 100,000. The case of landed properties is different as they can be priced at least SGD 100,000 to 300,000, which is largely due to the more extensive areas worked on and the complicated nature of the work involved.moneysmart Additionally, when planning your finances, it is crucial to consider not only the obvious expenses such as materials and labor but also the less obvious ones that may include hauling, getting permits, fixing hidden defects, and setting aside money for unexpected events, among others.moneysmart
3. Common Hidden Renovation Costs to Watch Out Fo
3.1 Structural Issues Hidden in the Walls
If a resale house is involved, among the problems not notified to the buyer might be poor plumbing, electrical wiring problems, water leaks, or mould, hiding behind walls and demanding expensive remediation before renovation starts. It is better to have an inspection done thoroughly or seek the help of professionals to do the pre-renovation check that will not produce any surprises.aurastone
3.2Permits and Approval Fees
In Singapore most of the renovation works require permits from HDB or the individual condo’s Management Corporation (MCST). If one was to ignore the process of applying for permits, it could lead to penalties, forced reversals, and incurring further costs.aurastone+1

5.4 Monitor Renovation Progress Regularly
Regular on-site inspections or asking for photo updates can be a good way to spot problems early on before they become expensive issues. Keep all your receipts, warranties, and contracts in an organized manner for future reference during the Defects Liability Period (which is usually 6 to 12 months).
5.5 Government Grants and Schemes
There are certain Government Grants and Schemes available which would be a great way to support a cash-strapped renovation project. For instance, the EASE or HIP schemes provide subsidies for necessary housing improvements that can help lower the costs of renovations for HDB flats that are eligible.moneysmart
How to Budget Smartly for Renovation in Singapore
| Renovation Aspect | Estimated Cost Range (SGD) |
| HDB BTO 3-room flat | 25,000 – 45,000 |
| Resale HDB flat | 50,000 – 90,000 |
| Resale Condo | 60,000 – 100,000 |
| Landed/Private Property | 100,000 – 300,000 |
Dividing your budget as 25-30% for living & dining areas and kitchens each, is correct as they are usually the most demanding in terms of work done.
While bedrooms and bathrooms normally cost less, still, the first priority should be given to their function and the aesthetics come after the basic needs are satisfied.
Keep an eye on your expenses all the time as it is the only way not to run into the issue of overspending.
Having a transparent and realistic renovation budget, distinguishing between the absolute necessities and the nice-to-have, plus setting aside some funds for contingencies will keep you away from the unpleasant surprise of costly financial losses.moneysmart
6. Financing Your Renovation Wisely
A lot of homeowners in Singapore, opt for personal loans or renovation loans as a means to finance their renovations.

When it comes to choosing the right way to finance, it is advisable to look at the interest rates, loan tenure and limits to arrive at the best solution for your renovation project. Be diligent in managing your repayment plans and steer clear of borrowing more than your limit so that your finances remain healthy.moneysmart
