The total budget depends on property size, material selection, design scope, and contractor fees.In this guide, we will take a detailed look at the realistic cost range of a Singapore renovation, the average renovation cost in Singapore, and some tips to help you stay on budget, including HDB renovation prices. The following section explains the key factors that directly influence full home renovation costs in Singapore.
Factors That Affect Full Home Renovation Monthly Costs in Singapore
The cost of a whole house renovation in Singapore varies from person to person. The main reason for this is that the cost depends on various factors. Below is a simple explanation of the factors that directly affect your budget
1. Size of Property
The larger the flat or house, the more work and materials are required. For example, while a3-room HDB flat renovation costs aroundSGD 35,000–45,000, a 5-roomHDB flat renovation costs up to SGD 60,000–80,000.
2. Type of Property
Renovation costs also vary by property type due to regulations and construction scope:
- HDB Flats: Governed by strict permits and renovation rules.
- Condominiums: Require customized interiors based on layout guidelines.
- Landed Houses: Involve extensive structural and material work.
3. Material Quality
If you use premium tiles, imported fittings or quartz countertops, the cost increases. Moderate quality carpentry work and laminate finish are relatively affordable.
4. Design Complexity
Design complexity directly impacts renovation cost. Minimalist designs reduce carpentry hours and material usage, while modern or luxury designs increase costs due to custom fabrication, designer fees, and premium finishes.
5. Contractor vs Interior Designer
Contractors usually do the work directly, while designers provide plans, mood boards, and material selection. Therefore, hiring a designer increases the service fee and project management charge.
6. Labor & Permit Fees
In Singapore, renovation permits(especially for HDB flats) and skilled labor cost – both are significant factors. Usually 10–15% of the total budget goes here.
Pro Tip:
The total cost of a 4-room HDB renovation using medium-quality materials is usually between SGD 45,000–55,000.

Monthly Cost Breakdown by Work Type
Renovation costs vary depending on the type of room or task. Sometimes, understanding the costs of these small tasks is the most important step in estimating the cost of the entire home. The table below shows the typical cost of each room or task and what types of tasks are included, based on average market prices in 2025.
| Area / Work Type | Typical Cost (SGD) | Common Works Included |
| Kitchen | S$ 10,000 – 25,000 | Custom cabinets, countertop, wall & floor tiling, plumbing line, electrical rewiring, lighting setup |
| Bathroom | S$ 5,000 – 12,000 | Waterproofing, new fittings, wall & floor tiles, vanity installation, heater & plumbing replacement |
| Flooring | S$ 6,000 – 15,000 | Vinyl / parquet / homogeneous tiles installation, skirting, floor leveling, hacking old flooring |
| Carpentry | S$ 8,000 – 20,000 | Wardrobes, TV console, shelves, kitchen cabinets, built-in storage, custom carpentry work |
| Painting | S$ 1,500 – 3,000 | Whole-house repainting, minor plaster repair, color consultation |
If you are renovating your kitchen and bathroom at the same time, the contractor can usually use a shared labor setup. This can save you about 8–10% on the total cost, as the same plumber and tiler are employed for both jobs.
Hidden or Additional Costs
Most homeowners budget for major tasks but there are somehidden costs that can become a big burden later on.These costs are usually incurred if not planned for in the beginning. The final bill may increase by 10–20%.
Below are some common examples of these hidden or additional costs:
Permit Fees (HDB Renovation Permit)

Most homeowners forget to budget for hacking and disposal, which can add up to SGD 2,000–4,000 depending on scope.
Electrical & Rewiring Works
Rewiring the entire house may require newelectrical points, lighting circuits, and power load upgrades. Costs range fromS$1,500 – 4,000, depending on the number of rooms and the quality of the wiring.
Project Management Fees
If you use an interior designer or project manager, they typically charge 10–15% of the total contract value. This fee includes site coordination, scheduling, and quality control.
GST & Contractor Mark-Ups
The current GST rate in Singapore is 9% (as of 2026), which is applied directly to the entire invoice. Some contractors may add an additional procurement or admin markup (3–5%).
