How to write a renovation scope of works, room by room

Zorvo Journal · Oct 2026 · ~6 min

A renovation scope of works is a written list of exactly what will be done in each room: what comes out, what goes in, the finishes you've chosen and which trades are needed. To write one, walk the property room by room, record measurements and condition, list every task and selection for that room, and clearly mark anything you're not touching as out of scope. Every quote and budget is priced from that list, so a vague scope almost always produces a vague (or blown) budget.

Key takeaways

• A scope of works describes the job. A quote prices it. Write the scope first.
• Work room by room, and for each room cover demolition, structure, services, surfaces, fixtures and finishes.
• Mark rooms and items you're not touching as "not in scope" so nobody prices work you didn't ask for.
• Name the specific products, or at least the standard, wherever you can. Loose descriptions are where quotes drift apart.

What is a scope of works in a renovation?

A scope of works is the plain-English description of the renovation you want done. In Victoria, Consumer Affairs Victoria describes it as the plans and specifications showing what and how an owner wants to build, and says it should be included when getting quotes and form part of the contract (CAV building definitions).

It doesn't need to be formal, just specific enough that two trades reading it would price the same job. "Update bathroom" isn't a scope. "Strip to frame, re-waterproof, new wall-hung vanity, floor-to-ceiling tiles, relocate the shower drain" is.

Why does the scope of works change your renovation budget?

Because cost follows scope. Every line you add, remove or describe loosely changes what gets priced, so the scope is the single biggest lever you have over the budget.

Three things happen when the scope is vague:

1. Trades fill gaps with assumptions. One keeps the plumbing positions, another moves them, and their numbers end up far apart.
2. Items get missed. Waterproofing, making good, rubbish removal and electrical upgrades are classic omissions that come back as variations.
3. "While we're at it" creeps in. Without a written list, extra work gets added on site one conversation at a time.

A room-by-room scope also shows where the money goes, so it's easier to cut the right things. If you're renovating to sell, our piece on renovations that close the gap covers how to decide what belongs in scope in the first place.

How do you write a scope of works room by room?

Walk the property in a fixed order, record what's there, what you want done and what you're leaving alone, then turn those notes into line items a trade can price.

1. List every room and space. Include the ones people forget: hallway, laundry, WC, garage, and the outside (facade, roof, gutters, fencing, paths).
2. Measure as you go. Floor dimensions, ceiling height, openings, and any walls being tiled, painted or rebuilt. Photograph existing services.
3. Note current condition. Water damage, cracking, sagging floors, old wiring or switchboards.
4. Write the tasks in trade order. Demolition and strip-out, structural, plumbing and electrical rough-in, waterproofing, linings, joinery, tiling and flooring, fit-off, painting, clean.
5. Name the selections. Product, model or at least the standard and finish (for example, "laminate benchtop" versus "stone benchtop"). In Victoria, Consumer Affairs Victoria notes that the cheapest quote may not include some items, or may use a base rate that doesn't cover the materials and finishes you actually want (CAV: getting quotes).
6. Mark what's out of scope. If a room isn't being touched, say so. If you're supplying something yourself, say so.
7. Lock it before you request quotes. Version it, date it and send the same scope to everyone.

What should a room-by-room scope checklist include?

Not every line applies to every job, but going through each one forces a decision instead of an assumption.

What are the most common scope of works mistakes?

The most common mistake is describing the result instead of the work ("modern kitchen"), so every trade imagines something different. Watch for:

• No out-of-scope list. Trades then price extras "just in case", or leave them out and add them later.
• Missing services work. Moving a sink, toilet or shower changes plumbing, drainage and often waterproofing. Moving or adding lights and power points changes electrical.
• Undecided selections. If a product isn't chosen, the quote will carry an allowance. In Victoria, Consumer Affairs Victoria explains these as prime cost items and provisional sums (CAV building definitions) and warns they can blow your budget and cause delays (CAV: managing project costs).
• Different scopes to different trades. A long brief to one and a phone call to another gives you quotes you can't compare.

Do you need a builder or designer to write a scope of works?

Not always. For cosmetic and like-for-like renovations, an owner or flipper can write a clear scope themselves. For structural changes, layout changes or anything needing a permit, you'll usually need drawings from a designer, draftsperson, architect or engineer, and your builder or building surveyor can tell you what's required.

Even then, writing your own room-by-room scope first forces decisions early and gives you something to check drawings and quotes against.

Can an app help you write a renovation scope?

Yes, if it keeps the scope tied to the rooms you actually walked. Zorvo Flip lets you walk the property on your phone, capture each room as you stand in it, and lock the scope before trades start pricing. It then turns that scope into an installed-cost budget (materials plus labour, without a builder's margin added). Flip only prices what you've entered: a room left empty or marked "Not in scope" is priced at zero and left out of the total, so there's no per-square-metre guess padding the number. You can then send trades the same scope, as covered in 6 practical ways to use Zorvo Flip. Try Flip on a real project for 3 months, then A$19/month.
