A homeowner's guide · 2026 edition
Real price bands, where the money actually goes, the hidden costs nobody budgets for — and the five questions to ask any builder before you sign.
Last updated: 2 July 2026
Most builders won't tell you what anything costs until you're deep in conversation. We think that wastes your time and ours.
I sit at a lot of kitchen tables in Newcastle and Lake Macquarie talking to families about renovations. Somewhere in the first ten minutes, someone slides a magazine photo across the table and asks, half-wincing, "Roughly what would this cost?" It's the right question — but most of the industry treats the answer like a trade secret, and by the time the number lands it's often $100,000 away from what you'd imagined.
This guide sets out the price bands we actually see on Newcastle and Lake Macquarie jobs in 2026, explains where the money goes, names the costs that catch people out, and shows you why two quotes for the same job can be $50,000 apart — and which one to trust. The numbers are guide figures, not quotes: a detailed, itemised quote after a site visit is the only number worth signing.
Chapter 01
These are the bands we see across real Newcastle and Lake Macquarie projects in 2026. Treat them as orientation, not gospel.
| Project | Typical 2026 range | Typical time on-site |
|---|---|---|
| Bathroom renovation | $20,000 – $45,000 | 3 – 5 weeks |
| Kitchen renovation (refresh) | from $30,000 | 4 – 6 weeks |
| Kitchen with custom joinery & stone | $60,000 – $80,000+ | 4 – 8 weeks |
| Whole-home renovation | from $80,000 | 3 – 6 months |
| Ground-floor extension | $3,000 – $4,500 / m² | 10 – 16 weeks |
| Second-storey addition | above ground-floor rate | 4 – 6 months |
| Knock-down rebuild | from ~$3,500 / m² | site-dependent |
Ranges are wide because scope varies enormously — a "bathroom renovation" can mean new tiles and tapware, or moving every fixture and re-waterproofing from the slab up. Custom cabinetry and stone lead times can stretch a kitchen schedule even when the budget holds. And per-square-metre rates climb for difficult sites, premium finishes and structural complexity.
If a number you've been given sits well below these bands, don't celebrate yet. Read Chapter 5 first — the cheapest quote is usually the least complete one.
Chapter 02
Take a typical mid-size renovation dollar and split it open. The proportions shift from job to job, but a professional builder's costs look broadly like this:
Licensed trades cost real money in the Hunter — and the difference between a good tiler and a cheap one is something you look at every day for twenty years. Materials are the slice you control most directly: selections can swing a kitchen by $30,000 without changing a single wall. And a builder quoting with no visible margin hasn't found a way around insurance, warranty and supervision — they've hidden it where you'll meet it later.
Chapter 03
The moment a load-bearing wall moves, you've added engineering, steel, certification and time. Opening a kitchen to a living room is wonderful — and it's a different budget to replacing cabinets in the same footprint.
Bathrooms, laundries and kitchens carry the most trades per square metre. Each wet area you add or relocate moves the total more than any bedroom ever will.
Flat-pack carcasses with laminate tops and custom joinery with stone are both "a new kitchen". They are not the same number. Decide your finish level early — it anchors everything.
A flat block with side access lets materials roll in. A steep Merewether block with no off-street parking means everything travels by hand, scaffold costs climb, and the schedule stretches.
Pre-1990 homes can hide asbestos. Older wiring may need upgrading before new work can be certified. Heritage areas add approval layers. Character homes are worth it — budget for what comes with the character.
Chapter 04
The renovation itself rarely blows the budget. It's the costs that never made it onto the spreadsheet.
DA or CDC fees, BASIX, certifier inspections, and any engineering, bushfire or heritage reports your site requires. Typically $2,000 – $8,000 on a renovation. We manage this process for our clients, but the fees are real either way.
Common in homes built before 1990 — eaves, bathroom linings, fences, vinyl underlay. Licensed removal can run $2,000 to $15,000. If your home is pre-1990, get this assessed before you set your budget, not after demolition day.
Termite damage, rotten subfloors, corroded plumbing. Your protection isn't a builder who promises no surprises — it's a builder who prices them honestly through a written variation process when they appear.
A whole-home renovation can mean three to six months of rent, storage and moving costs. Staged renovations can sometimes let you stay — we'll tell you honestly at quote stage whether that's practical.
Choose tiles above the allowance and the difference is yours. The same goes for every "while we're at it". Each one is small. Ten of them is a second bathroom you didn't plan.
Rule of thumb: hold a contingency of 10–15% of contract value — 15–20% for pre-1990 homes. If you don't spend it, it becomes the furniture budget. If you do, it saved the project.
Chapter 05
You collect three quotes for the same renovation: $180,000, $205,000 and $155,000. Same drawings, same house. How?
The most complete quote includes the scaffold, the waterproofing certificate, the skips, the final clean. The cheapest one includes a line that says "excludes preliminaries". You'll pay for those either way — the only question is whether you saw them coming.
A $40/m² tile allowance looks great in a quote and survives contact with exactly zero tile showrooms. The quote wins the job; the variations win it back.
"Excludes painting." "Excludes asbestos removal if found." Every exclusion is a future invoice. Read the exclusions list before you compare totals — it's where cheap quotes live.
A builder who quotes below cost doesn't absorb the difference — they recover it in variations, cut corners, or don't finish. All three cost you more than the honest margin would have.
The test: ask each builder to walk you through their quote line by line. The one who can — happily, in plain English, with nothing vague — is showing you how they'll run your job.
Chapter 06
| Stage | Realistic duration |
|---|---|
| Enquiry to first response | 1 business day (ours, at least) |
| Site consultation | booked within 1 – 2 weeks |
| Detailed quote & proposal | 1 – 3 weeks after site visit |
| Design & approvals — CDC pathway | typically weeks |
| Design & approvals — DA pathway | typically months |
| Contract signing to start on-site | 4 – 12 weeks |
| The build itself | see Chapter 1 bands |
Time becomes money three ways: material lead times (custom joinery and stone can run six weeks or more), approval pathways (a CDC project moves months faster than a DA — worth knowing before you fall in love with a design), and start-date pressure (a builder who can start tomorrow is either very well organised or very quiet — ask why).
Chapter 07
Take the Chapter 1 range for your project type, position yourself within it using the Chapter 3 factors, then add contingency. If it's beyond reach, shrink the scope — not the quality of what remains.
15–20% for pre-1990 homes. Keep it out of the contract and out of the selections conversation.
Structure, waterproofing, windows and joinery carcasses are forever — buy quality once. Tapware, light fittings and hardware can be upgraded any weekend.
Every selection made after the build begins costs more than the same selection made before it. A builder who pushes you to finalise selections early is protecting your budget, not rushing you.
The right comparison is "what does this number include", never "which number is smaller".
Twelve items. When you can tick all twelve, you're ready to build — with anyone. (The full printable version is in the PDF below, along with the five questions to ask any builder.)
The full 14-page guide — every price band, the hidden-cost chapter, the printable checklist, and the five questions to ask any builder before you sign. We'll email it to you.
No pressure follows this guide — most people who read it are six to eighteen months from building, and that's exactly the right time. When you're ready, we'll arrange a site consultation and give you a real number to plan around.
