New vs resale condition
Resale homes usually carry more cost uncertainty because hacking, removal, haulage, making-good works and hidden site conditions can only be confirmed properly after inspection.

Before You Budget
What to consider before using a renovation cost estimate
Use the calculator first, then read these short notes to understand why Singapore renovation budgets can move after floor plan review, site inspection and material selection.
Renovation vs move-in budget
A renovation quote does not always cover furniture, loose appliances, curtains, smart home items or moving costs. Keep a separate move-in budget before committing your full cash reserve.
Scope drives the estimate
Carpentry, flooring, hacking, electrical works, plumbing and toilet works are common cost drivers. The more detailed your scope, the more useful the estimate becomes.
Keep a practical buffer
Treat the result as a planning range, not a final quote. Site measurements, management requirements, material choices and revised design details can still change the final budget.

Cost Comfort Guide
How to read your renovation estimate
The estimate is most useful when you compare it against your desired finish level, available budget and how much uncertainty the site may carry.
Lower Range
Budget-conscious scope
Usually works best when finishes are simple, hacking is limited and major carpentry is controlled.
Middle Range
Typical market range
Often the most realistic planning zone for homeowners who want a balanced renovation without over-customising every area.
Higher Range
Premium or complex scope
Usually reflects heavier resale works, more custom carpentry, premium materials or higher coordination requirements.
Renovation Budget FAQ
Singapore renovation cost questions
Short answers for homeowners comparing HDB, BTO, resale, condo, kitchen and toilet renovation budgets before requesting an itemised quotation.
How accurate is this renovation calculator?
It is a planning estimate based on selected scope, property type, size and common Singapore renovation cost items. Final pricing still depends on site measurements, hacking condition, material selection and approval requirements. For design direction before confirming scope, you can also try our HDB renovation style quiz.
Can it estimate HDB and BTO renovation costs?
Yes. The calculator includes HDB flat types, BTO/new condition and resale condition so homeowners can compare broad budget ranges for common HDB renovation scopes.
How much does a 4-room HDB renovation cost in Singapore?
A 4-room HDB renovation can vary widely depending on whether it is a new BTO or resale flat, the amount of carpentry, hacking, flooring, electrical work and toilet work involved. Use the calculator to adjust the scope before treating the result as a planning range.
Why does resale renovation usually cost more?
Resale homes often involve hacking, haulage, removal, making-good works and unknown site conditions. These can increase the final renovation cost after inspection.
Can I use it for kitchen or toilet renovation only?
Yes. Choose kitchen-only or toilet-only at the first step. The estimate will focus on relevant items such as carpentry, worktop, tiling, plumbing, sanitary fittings and shower screens.
What renovation works usually affect cost the most?
The largest cost drivers are usually carpentry, masonry and tiling, hacking and removal, electrical works, plumbing works and material selections such as worktops, flooring and fittings.
Does the estimate include GST?
The calculator includes a GST toggle at the estimate step. Switch it on to view a GST-inclusive planning range.
Should I include furniture and appliances in this renovation estimate?
This calculator focuses on renovation works. For a more complete move-in budget, separately plan for loose furniture, appliances, curtains, bedding, lighting purchases and moving expenses.
How much contingency should I keep for renovation?
A practical buffer is useful because final costs can change after site inspection, floor plan review, material confirmation and management or HDB-related requirements.
How do I get a confirmed quotation?
Send the estimate to ID Work Studio on WhatsApp. A confirmed quotation requires floor plan review, site measurements, material confirmation and final scope checking.
Recommended Next Step
After estimating renovation cost, plan your full move-in budget
