Renovation Cost Guide Singapore 2026

How much should you budget for a Singapore home renovation? Start with the work required in your home, then compare written quotations for the same scope. A headline package price or rate per square foot cannot tell you the final cost without quantities, specifications, site conditions and exclusions.

This guide helps you build a budget and question a quotation. Nestly does not currently have a verified 2026 pricing dataset, so the checklist below is not a market-price benchmark or a personalised estimate.

1. Separate renovation work from your total move-in budget

Make separate lists for the renovation contract, items you buy yourself and other move-in expenses. Mark every item as included, excluded or awaiting confirmation. Do not treat an unpriced item as free.

• Contracted work: record the agreed demolition, finishes, carpentry, services, installation and other work.
• Owner purchases: list appliances, furniture, lights, sanitary fittings, curtains and other purchases relevant to your home. Confirm who supplies, delivers and installs each item.
• Other expenses: consider moving, storage or temporary accommodation if needed. Ask about applicable site arrangements, deposits and fees; distinguish refundable deposits from expenditure.
• Unresolved work: keep a separate allowance for items that need inspection, measurement or a final selection. Agree how the estimate will become a confirmed price.

Check whether the quoted total includes applicable tax and all mandatory charges. Keep your household budget ceiling separate from the amount committed to the renovation contract, so other purchases remain visible.

Try an itemised planning estimate

Our free renovation cost calculator lets you add or remove HDB work items, enter quantities, set allowances and contingency, and compare the result with your total budget. You can print the itemised summary for a discussion with your designer without submitting contact details.

The calculator uses midpoints of researched price ranges, not statistical market medians or verified final project costs. It budgets only the selected items; confirm missing work, specifications and GST before committing. Condo and landed owners can enter their own estimates rather than applying the HDB work-item rates.

2. Ask what each renovation cost includes

Use these questions when discussing an itemised quotation. A lower unit rate is only comparable when the unit, quantity and specification match.

• Carpentry: what dimensions, internal layout, material, finish and hardware are included? Are the countertop, accessories and installation separate?
• Flooring: what area is measured and in which units? Does the price include removal, surface preparation, skirting, installation and disposal where needed?
• Bathroom and kitchen work: separate surface work, fittings, plumbing and installation. Ask the contractor to explain proposed waterproofing work and checks where applicable.
• Electrical: define each quoted point and distinguish fittings, wiring and installation. Ask which items need assessment by the appropriate qualified trade.
• Painting: confirm the rooms and surfaces covered, preparation and specified paint system. Identify repairs priced separately.
• Demolition and site work: identify exactly what is removed, retained and protected, plus disposal and cleaning responsibilities.

3. Compare the same scope before comparing totals

Send each firm the same floorplan, room priorities, retained items and intended finishes. Ask them to mark assumptions and exclusions. A site assessment and measurements may be needed before the scope can be confirmed.

Illustrative comparison, not a price example: one kitchen quotation includes cabinets and installation; another also includes the countertop, removal of old cabinets and disposal. Their totals do not describe the same work. Request the missing items and matching specifications before deciding which proposal offers better value.

For each difference, record: the item, each firm's included scope, the unanswered question and the confirmed adjustment. Compare the revised totals only after those gaps are resolved. Save dated versions of the quotations so an earlier assumption is not mistaken for a final commitment.

4. Plan for changes without guessing a universal percentage

Ask which conditions remain unknown and which decisions remain open. A retained floor needing inspection and an undecided cabinet finish are different uncertainties; list them separately with the proposed next step.

Discuss an allowance appropriate to those uncertainties rather than assuming one percentage suits every home. Before approving extra work, request a written description, price and effect on the schedule. Keep approved changes in a running budget alongside the original contract and owner purchases.

5. Agree payment milestones and keep records

Review the written work and payment schedules together. Clarify what completion means at each milestone and how changes, defects and outstanding items will be recorded. Do not assume every firm's payment split or warranty is the same.

CASE's consumer advice recommends comparing quotations, researching contractors, avoiding large upfront prepayments and negotiating progressive payments linked to key project milestones. Read the actual terms before committing and retain quotations, signed changes, invoices and receipts.

Prepare your brief before requesting quotations

Bring a floorplan, your must-have work, items to retain, intended move-in timing and a budget that distinguishes renovation from other purchases. Use our BTO planning guide or resale HDB checklist for property-specific preparation, and the designer-selection guide to assess the team as well as the quote.
