# How much does a renovation cost? Build a realistic budget

Build a renovation budget from assessed repairs, optional upgrades, complete quotations and a clear record of uncertainty and approved changes.

A useful renovation budget begins with the house’s condition and the outcome you want, not a single price per square metre. Two homes of similar size may need very different work, and two owners may include different things when they say renovation. Build the budget in layers: assessment, required repairs, functional improvements and optional finishes. This approach helps you see which decisions must be made first and where you still need quotations or professional advice.

## Separate repair needs from improvement wishes

Create a room-by-room list and give each item a purpose. Repair work addresses an assessed problem; functional improvements change how the home works; appearance changes deliver a preferred look. Ask the professionals which items depend on others before assigning priorities. For example, a planned finish may depend on resolving a service issue first. This classification is an owner planning tool, not a diagnosis. A visible symptom should remain an assessment item until the responsible specialist explains the appropriate repair.

## Price the complete work surrounding each repair

Ask quotations to include the associated access, protection, removal, disposal and reinstatement relevant to the proposed repair. A plumbing intervention and the restoration of the affected wall may be supplied by different parties, but both belong in the owner’s budget. Identify whether fixtures, delivery, installation and final cleaning are included in each package. Mark official payments and professional appointments separately when they apply, and confirm the appropriate procedural route through the responsible professional rather than assuming all renovation work has identical requirements.

## Keep uncertainty visible instead of hiding it in a total

Give uninspected areas and unresolved choices their own lines. Ask what investigation would make each estimate more reliable and whether it should happen before tendering the main work. Record the difference between a confirmed quotation, an allowance and an unanswered item. Discuss a reserve with the team based on these identified uncertainties and your ability to respond to them. Do not treat a universal percentage as proof that the budget is protected, especially when a major part of the scope remains undefined.

## Compare bids using the same quantities and selections

Provide bidders with one scope and the same material selections or clearly stated allowances. If one offer includes a complete room and another includes only a local repair, resolve the boundary before comparing their totals. Check how taxes are stated and how long the quotation remains open. Keep a separate list of owner-supplied items, including any handling or installation charge. The result should show what the family will actually need to fund, rather than merely which contractor presents the smallest first-page amount.

## Choose the order in which you commit money

Avoid placing irreversible orders for finishes while the underlying repair or layout remains unresolved. Ask the team which purchases can be confirmed and which depend on an assessment or final measurement. In a hypothetical case, the owner postpones decorative panels to fund a confirmed repair and its reinstatement. Record the panel work as deferred, not silently removed from the project. This preserves the intended future scope and prevents someone from treating a temporary budget decision as approval for a different final design.

## Track commitments separately from payments

Maintain columns for the accepted contract, approved changes, amounts paid and commitments still outstanding. Paying an invoice changes cash paid; it does not necessarily change the total amount already committed. Add pending quotations without presenting them as approved expenditure. For each proposed variation, request its scope, amount and programme effect before deciding. Review the remaining unpriced work alongside the remaining funds. That comparison is more useful than looking only at the bank balance or the percentage of the original contract paid.

## Your practical checklist

1. Classify assessment, repairs, functional upgrades and appearance changes.
2. Include protection, removal and reinstatement around each intervention.
3. Identify allowances and uncertainties before choosing a reserve.
4. Track approved commitments, payments and still-unpriced work separately.

## Frequently asked questions

### Can I estimate the whole renovation from floor area?

Area can help organize quantities, but it does not describe the existing condition, repair extent or selected finishes. Use an assessed scope and comparable quotations for the actual budget.

### How much contingency should I keep?

Discuss identified uncertainties and their consequences with the project team. An unexplained percentage cannot replace understanding the work that has not yet been assessed or priced.

### What should I defer if the budget is exceeded?

Review priorities with the responsible professionals first. Consider optional improvements only after understanding the required repairs and dependencies; do not remove a technical requirement merely to reduce the total.
