Melbourne Renovation Cost Guide
Start with a realistic budget — not an online calculator guessing at your home.
Brownlow Building's guide explains realistic planning ranges, what actually moves renovation costs and how to compare builder quotations before you commit.

Cost Guide
Realistic planning ranges, the factors that move budgets, and how to compare renovation quotes before you commit.
Better budgeting starts with better information
Renovation pricing is not a single square-metre number
The same floor area can represent two completely different construction projects. Kitchens, bathrooms, structural openings, existing conditions, services, access and finish level all change the amount of work inside that square metre. The guide is designed to help you understand the scope behind the number.
What's inside
A practical guide to planning the right budget
Not a sales brochure full of vague averages. The guide walks through the types of work Brownlow sees in real Melbourne renovations and explains the decisions that materially change cost.
Bathrooms & Ensuites
Realistic planning ranges, what is usually included and the details that push wet-area budgets higher.
Kitchens & Pantries
How cabinetry, stone, appliances, service relocation and structural changes affect kitchen renovation costs.
Whole-Home Renovations
Why whole-home projects vary so widely and how to think about scope, existing conditions and finish level.
Extensions & Additions
Why extension costs are driven by much more than floor area — especially structure, wet areas and connections to the existing home.
How to Compare Quotes
A practical checklist for comparing scope, assumptions, exclusions and allowances — not just the number at the bottom.
Budget Risk & Contingency
The common reasons renovation budgets move and what to allow for before committing to construction.
Why budgets move
The expensive part is often what you cannot see in a photo
A beautiful finished room tells you almost nothing about what had to happen behind the walls, below the floor or within the existing structure to deliver it.
Explore Home Renovations MelbourneExisting conditions
Hidden damage, movement, old services, moisture and previous work can materially change the scope.
Structural changes
Removing walls, creating openings, modifying roof loads and adding steel increase design and construction complexity.
Wet areas & services
Bathrooms, laundries and kitchens bring waterproofing, plumbing, electrical and ventilation requirements.
Access & buildability
Restricted access, occupied homes, apartments and difficult material handling all affect delivery cost.
Documentation & approvals
Engineering, drafting, permits, energy requirements and specialist documentation may form part of the project.
Quality & finish level
Custom joinery, premium fixtures, stone, specialist finishes and detailed workmanship quickly change the final investment.

Renovation costs in Melbourne
Use cost information to test the project — not to manufacture a fake quote
Renovation costs in Melbourne can vary substantially even between homes that look similar from the street. Older housing stock, previous additions, structural alterations, plumbing and electrical upgrades, waterproofing, access and the quality of the existing construction can all affect the work required.
That is why Brownlow uses planning ranges as an early budgeting tool rather than presenting an online calculator as if it were a quotation. The goal is to help homeowners understand whether the likely investment and desired scope are broadly aligned before they commit heavily to drawings, selections or tendering.
Once a project moves beyond early planning, the next step is a clearer scope, existing-condition review and appropriately developed documentation so the project can be priced on what is actually being built.
Frequently asked questions
Renovation budgeting questions
How accurate are renovation cost guides?
A cost guide is useful for establishing a realistic planning range, but it cannot replace a developed scope and site-specific pricing. Renovations are affected by existing conditions, structure, services, access, selections and documentation.
Why not use a square-metre rate?
Square-metre rates can be a rough sanity check, but two extensions of the same size can have completely different trade intensity. A simple living-room addition and an extension containing a kitchen, ensuite and major structural openings are not the same project.
Are the figures in the guide a quotation?
No. The figures are indicative planning ranges only. A formal construction price can only be developed once the project scope, documentation, selections and site conditions are sufficiently understood.
Who is the guide designed for?
Melbourne homeowners considering a substantial renovation, extension, kitchen, bathroom or multi-area project who want to understand realistic budget territory before progressing too far with design or builder quotations.
What should I do if the likely investment is higher than expected?
Use the guide to identify the biggest cost drivers, then reconsider scope, staging, layout and finish level before spending heavily on detailed design. Brownlow can also discuss whether your objectives and budget are broadly aligned.
