Renovating a Sydney home sounds fun until you’re three months in, living out of a microwave, and wondering how a kitchen backsplash ended up costing more than your last car. It happens to almost everyone. The good news is that most of the pain is predictable, which means most of it is avoidable.
If you’re thinking about pulling a wall down, adding a second storey, or finally fixing that bathroom that time forgot, here’s what actually matters before you start.
Sydney Renovations Play by Their Own Rules
You can read every renovation blog on the internet, but most of them are written for suburbs where the block is flat, the neighbours are 20 metres away, and the council approves anything with a pulse. Sydney is not that.
Terrace houses in Paddington, Federation homes in Haberfield, semis in Marrickville, apartments in strata buildings across the eastern suburbs. Each one comes with its own quirks. Some are heritage-listed. Some share a party wall with a neighbour who has strong feelings about vibration. Some sit on sandstone that makes excavation a small nightmare.
None of this is a reason not to renovate. It’s a reason to plan properly and not assume your project looks like the one you saw on Instagram.
Get Your Budget Honest Before Anyone Picks Up a Hammer
The number in your head is almost certainly too low. Not because you’re bad with money, but because renovation costs in Sydney have moved fast, and the ballpark figures floating around in old forum threads are stale.
A few realities worth sitting with:
- A full kitchen renovation, done properly, usually starts around $30k and can easily land at $60k or more depending on cabinetry and appliances.
- Bathrooms are small rooms with a lot going on. Waterproofing, tiling, plumbing, electrical, ventilation. Expect $25k to $40k for a decent job, more if you’re moving fixtures.
- Extensions and second-storey additions typically start north of $400k once you factor in structural work, and that’s before you start choosing finishes.
Whatever budget you land on, add a contingency of at least 10 to 15 percent. Something will come up. Old wiring, asbestos, rotted joists, a council condition you didn’t expect. If nothing goes wrong, you’ve got a nicer light fitting fund. That’s a fine problem to have.
The Council Question
Development approvals in Sydney vary wildly depending on which council you sit under. Some are quick and reasonable. Others will have you filing paperwork for a year to move a window.
Before you fall in love with a design, check whether your project needs a full Development Application, whether it can go through Complying Development, or whether it’s minor enough to skip approval entirely. A qualified designer or private certifier can tell you inside an hour. Don’t guess.
If your place is heritage-listed or in a conservation area, that changes things again. It doesn’t mean you can’t renovate. It means the front of the house probably has to stay recognisable, and you might need specific materials for anything visible from the street.
Choosing Who Does the Work
This is where most renovations succeed or fail. A great designer paired with a shoddy builder gives you a beautiful drawing and a broken house. A great builder working from a vague brief gives you something functional that doesn’t quite feel like yours.
For anything bigger than a single room, you generally want three people in the room early: a designer or architect, a builder, and, if the scope is significant, a project manager. Some firms roll all three under one roof, which can simplify the process if you trust the team.
When you’re comparing options, look for home renovation experts in Sydney who can show you completed work in homes similar to yours. Terrace-house specialists know things that apartment specialists don’t, and vice versa. Ask to speak to past clients. Ask what went wrong on their last three jobs and how they handled it. Anyone who says nothing ever goes wrong is either lying or hasn’t done enough projects.
A few practical checks:
- Confirm they’re licensed with NSW Fair Trading and that the licence covers residential work at your project’s value.
- Ask for a certificate of currency for their insurance.
- Get the scope of works in writing, not a two-line quote.
Do Things in the Right Order
A renovation done out of order costs twice. Some rough guidance on sequencing:
- Figure out your scope and non-negotiables before you talk to anyone. Cook a lot? Prioritise the kitchen. Work from home? The layout of your office matters more than another bathroom.
- Get a rough design and a rough budget from a designer. Not final, just directional.
- Talk to a builder about buildability. A design that looks great on paper but requires three days of jackhammering through sandstone is a design worth revisiting.
- Handle approvals.
- Lock in fixtures and finishes before construction starts. Waiting for a backordered tap can hold up an entire trade.
- Then build.
Skipping steps almost always shows up later as a change order, and change orders are where budgets go to die.
Living Through It
Renovations take longer than the quoted timeline. Not always, but often enough that you should plan for it. If someone tells you a full kitchen is done in two weeks, ask what happens if the stone benchtop is delayed, or if the electrical fails inspection first time. A realistic answer beats an optimistic one every time.
If you can move out for a big job, do it. If you can’t, seal off the work zone properly, set up a temporary kitchen somewhere you don’t mind getting dusty, and pick your battles. Trying to keep a fully functional household running through a major renovation is how partners start snapping at each other over cutlery.
The Payoff
Done well, a renovation is one of the few things you can spend money on that pays you back every single day. A kitchen that fits how you actually cook. A bathroom that doesn’t feel like a wet cupboard. A living space that catches the morning light instead of blocking it.
Get the planning right, be honest about the budget, pick your team carefully, and the rest is mostly waiting. Which, compared to living in a house that doesn’t work for you, is a pretty good trade.
