How much does an interior renovation cost in Sydney?
Interior renovation costs depend on two things: what you are renovating and the finish level you choose. Area-based items like painting and flooring scale with your floor area. Rooms like kitchens and bathrooms are priced as flat costs based on scope and materials.
The table shows typical ranges for a mid-range finish. Use the calculator above for a personalised estimate tailored to your home, or download our free renovation blueprint for the full planning guide.

| Laundry | $18,000 - $28,000 |

| Flooring (per m2) | $105 - $150 |
| Lighting (per m2) | $28 - $45 |

What else affects the price?
The calculator gives you a realistic range, but every home is different. Here are the main variables that move the number up or down.
- Layout changes Removing walls, reconfiguring rooms, or relocating plumbing and electrical adds structural and engineering costs.
- Property type Apartments cost more due to strata requirements, restricted hours, and access logistics. Townhouses may add a small premium.
- Home age Homes over 30 years old may need asbestos assessment, rewiring, plumbing upgrades, or structural repairs before renovation can begin.
- Finish level The gap between standard and premium finishes can double the cost of any room. Materials, fixtures, and design complexity all contribute.
- Site access Narrow streets, limited parking, upstairs rooms, and small doorways can increase labour and material handling costs.
- Scope creep Adding rooms or upgrading finishes mid-project is one of the most common reasons budgets blow out. Lock in your scope early.

How much does an interior renovation cost in Sydney?
Interior renovation costs in Sydney vary widely depending on the scope. A cosmetic refresh (painting, flooring, lighting) for a typical 3-bedroom house might run $30,000 to $60,000. A full interior renovation including a kitchen, bathrooms, and structural changes can range from $150,000 to $300,000 or more. Our calculator gives you a personalised estimate based on your specific requirements.
What does the interior renovation calculator include?
The calculator covers seven scope items: kitchen, bathrooms, laundry, new flooring, painting, new lighting, and built-in joinery. You select what applies to your project, tell us your floor area and finish level, and the calculator produces an itemised estimate. It also factors in property type, home age, bathroom count with volume discounts, and layout changes.
How accurate is this renovation cost calculator?
The calculator provides a realistic range based on typical Sydney renovation costs. It factors in your floor area, scope of work, finish level, property type, and home age. For a precise quote tailored to your property, we recommend booking a free consultation where we can assess your space in person.
What is the difference between standard, mid-range, and premium finishes?
Standard finishes include quality materials like hybrid flooring, laminate benchtops, and good fixtures. Mid-range upgrades to engineered timber, stone benchtops, quality tapware, and custom cabinetry. Premium includes designer selections, natural stone, premium appliances, architectural lighting, and custom everything. The finish level has the biggest impact on your total cost.
Does the calculator account for multiple bathrooms?
Yes. If you select bathrooms in your scope, the calculator asks how many you are renovating. The second bathroom is discounted by 15%, the third by 25%, and the fourth by 30%, reflecting shared project management and site costs. Each bathroom is still priced individually based on your chosen finish level.
Why does property type affect the renovation cost?
Apartments typically cost 5 to 10% more than houses due to strata requirements, restricted working hours, lift access, parking logistics, and material handling. Townhouses may add a small premium for restricted site access. The calculator applies these multipliers automatically based on your selection.
Why does the age of my home affect the estimate?
Older homes (30+ years) often require additional work that is not always visible upfront: asbestos assessment and removal, rewiring to meet current standards, plumbing upgrades, and structural repairs. Homes aged 10 to 30 years may need some electrical or plumbing updates. The calculator adds a 3 to 12% adjustment based on your home age.
Is the calculator free to use?
Yes, the interior renovation cost calculator is completely free. You receive an instant estimate on screen. If you provide your contact details, we can also send you a detailed breakdown by email and follow up with a personalised consultation.
