Start With Goals, Priorities and Project Scope

Most renovation budgets blow out before a single wall comes down. The cause is rarely bad luck. It is a vague scope that nobody wrote down.

Homeowners often arrive with a Pinterest board and no written brief. That is where costs start to drift.

Project scope is the written list of what the renovation will and will not include. It covers rooms, fixtures, structural work and finishes.

Defining What the Renovation Must Achieve

Write down three things before anything else:

• The problem: a cramped kitchen, a dated bathroom, poor light, no storage
• The outcome: what the room must do for your household in five years
• The non-negotiables: the one or two items you will not compromise on

Then split your wish list into must-haves, nice-to-haves and later. A common mistake is treating everything as a must-have. In practice, this means the builder has to price the lot, and the quote comes back higher than it needs to be.

Watch out: if you skip this step, you will spend money on finishes for a layout that does not work. Fix the floor plan first, then the surfaces.

Build a Home Renovation Budget Planner Before You Commit

A home renovation budget planner is a simple document that lists every cost line and the money set aside for each. It is the single most useful tool in the whole process, and a spreadsheet will do.

Build it in four parts:

1. Construction: labour, materials, trades
2. Approvals: permits, inspections, certificates
3. Professional fees: design, engineering, surveying
4. Buffer: the money you never touch unless something goes wrong

Pricing depends on the size of the job, the materials you choose and the condition of the existing structure. For current prices or a quote for your project, visit the Archibuilt website.

Indicative Cost Ranges by Project Type

Use these ranges as a planning starting point, not a quote. They are broad because finishes and structural condition move the number more than floor area does.

• Bathroom renovation: a cosmetic refresh (tiles, fixtures, paint) sits at the lower end; a full strip-out with waterproofing, new plumbing and custom cabinetry sits at the upper end. Expect the upper end to be roughly two to three times the lower end for the same room.
• Kitchen renovation: a like-for-like replacement is the cheapest path; moving plumbing, adding an island or specifying stone worktops pushes the figure up sharply. Cabinetry and worktops are usually the two largest line items.
• Whole-of-house internal renovation: painting, flooring, lighting and joinery across multiple rooms. The per-square-metre rate is lower than a kitchen or bathroom because there is less wet-area work, but the total is higher.

A common pattern is for homeowners to budget from the finish they can see (tiles, taps) and underestimate the work they cannot see (waterproofing, framing, electrical). The invisible work is usually the larger share of the bill.

Setting a Contingency That Actually Holds

Set aside a contingency fund before you sign anything. A buffer is worth setting aside for older homes, where hidden problems are more likely. Treat it as part of the budget, not spare cash.

A more useful mechanism is to split the contingency into two pots:

• Known unknowns: items you suspect but have not priced, such as asbestos removal or a bathroom that may need re-waterproofing. Estimate these now and hold the money.
• Unknown unknowns: genuine surprises, such as a wall that is not load-bearing as drawn or a slab that needs levelling. This is the pot you do not touch until the problem appears.

If you spend the first pot, you still have the second. If you spend both, the project is in trouble and you need a conversation with your builder, not a bigger credit card limit.

Quotes, Variations and Payment Safeguards

When comparing quotes, check that each one lists:

• What is included and excluded
• A schedule of progress payments
• The time frame for each stage

Watch out: the cheapest quote is often the one with the most exclusions, so compare scope line by line rather than comparing totals.

Set a Realistic Home Renovation Timeline and Work Sequence

Your home renovation timeline is a schedule that maps each stage to a start and finish date.

The project sequencing for most renovations follows the same order:

1. Design and approvals
2. Demolition and strip-out
3. Structural work and rough-in
4. Waterproofing and inspections
5. Tiling, cabinetry and fit-off
6. Painting, cleaning and handover

Be realistic about the approval stage. Council and certifier timeframes vary, and a design change mid-build can push the whole schedule back. A common mistake is booking trades before approvals are finalised.

Build in slack at two points: after approvals, and before fit-off.

Understand Renovation Permits and Approvals Before Work Starts

Renovation permits and approvals are the official consents your project needs before work begins. What applies depends on the type and scale of the work, and on the rules of your local council.

Broadly, the approvals can include:

• Planning permission for certain extensions, changes of use, or work in a heritage or bushfire overlay
• Building permits for structural, plumbing and electrical work
• Owner-builder or contractor certificates depending on who manages the job

The Victorian Building Authority guidance on building permits sets out when a permit is required and what inspections apply. Your local council website lists any planning controls for your property, including heritage or bushfire overlays.

The Three Approval Pathways You Need to Know

Most residential renovations fall into one of three pathways, and knowing which one applies to you is the single biggest factor in how long the approval stage will take.

1. Exempt or complying development. Minor internal work, replacing a kitchen, updating a bathroom in the same footprint, painting, often needs no planning approval at all. A building permit may still be required for plumbing, electrical or structural changes. Check your council’s exempt development list before assuming you are clear.
2. Complying development or a fast-track permit. Some extensions and alterations that meet fixed standards (setbacks, height, floor area) can be approved through a faster code-based pathway rather than a full development application (Complying Development | Planning Portal). This is where a good designer earns their fee, because the difference between a complying and a non-complying design can be months.
3. Development application (DA) and full building approval. Larger extensions, second storeys, changes of use and work in sensitive overlays usually need a DA through council, followed by a building permit. This is the slowest path and the one most likely to attract neighbour objections.

What Actually Drives Approval Timeframes

Approval timeframes vary by council and by the complexity of the application, but a common pattern is:

• Exempt or complying work: a few weeks for the permit, assuming drawings are complete
• Development application: often two to four months, longer if neighbours object or the council requests further information
• Heritage or bushfire overlays: add weeks, because additional referrals and reports are usually required

Watch out: a design change made after the DA is lodged can reset the clock, so lock the layout before you submit rather than during the process.

Documents You Will Need Ready

Approvals stall most often because the paperwork is incomplete. Before you lodge anything, have ready:

• Scaled architectural drawings and a site plan
• A statement of environmental effects or equivalent, where required
• Structural engineering details for any load-bearing changes

Get every approval in writing before demolition day. A verbal assurance from a council officer is not an approval, and starting work early is the fastest way to turn a straightforward renovation into a dispute.

Approval timeframes vary by council and complexity, but here is the common pattern the article describes.

Choose a Builder and Put the Contract in Writing

Choosing a builder comes down to evidence, not charm. Ask for proof of registration, insurance and recent work you can inspect. Then check the details.

Use this vetting checklist:

• Registration and licence number confirmed
• Insurance certificates supplied
• At least two recent projects viewed in person

The contract must state the scope, the price, the payment schedule, the timeline and how changes are handled. Our guide on how to find reliable home builders walks through the full vetting process.

A common mistake is paying a large deposit up front. Progress payments tied to completed stages protect both sides.

Work Through a Practical Home Renovation Checklist

A home renovation checklist is a running list of tasks and decisions, organised by stage. It keeps the project moving and stops small items falling through the cracks.

Here is the sequence we work to:

• Finalise the brief and scope
• Set the budget and contingency
• Confirm approvals and permits

Plan for Living Arrangements and Disruption During Construction

Decide where you will live before demolition begins. Kitchens and bathrooms are the hardest rooms to do without, and most households underestimate how long they will be without them.

Plan for:

• A temporary kitchen: a kettle, microwave and fridge in another room
• Bathroom access: which bathroom stays usable, and for how long
• Dust and noise: sealed doorways and a clear path for trades

Set a single point of contact for the builder and agree how often you will get updates. Clear communication is what keeps a renovation calm. If you are unsure how much disruption to expect, ask before you sign.

Get a Quote and Lock In Your Renovation Plan

You now have a scope, a budget, a timeline and a shortlist of builders. The last step is turning that into a firm quote and a signed plan.

Bring these to the quote conversation:

• Your written scope and priorities
• Your budget and contingency
• Your preferred timeline
