Breaking down home construction costs

For new builds in Sydney, the cost of a new home for a finished house starts at $777,500, according to research from RLB. Features such as kitchens, bathrooms and extras can substantially vary the cost as these aspects can include individual taste, expensive finishes and an array of appliances. 

 

What is the price of a typical home in Sydney?

Land plots in Sydney have remained fairly consistent at an average size of 375 sqm over the past few years, however many homeowners try to make the most of the available land by focusing on smart designs. Purchasing the land in Sydney’s premium housing market is commonly a significant expense when building a new house in the metropolitan, according to the Urban Development Institute of Australia’s 2024 State of the Land report. The median residential land lot price in Sydney was reported as $641,250 in 2023.

Today, many homeowners building their dream aim for a substantial home for their growing families and the average newly constructed home is estimated at 325 square metres. RLB data shows that a home of this size would vary in price from $777,500 to $2.3 million based on individual preferences and budgets.

To best plan the cost of a new home, using the price per square metre may be useful. Another common way to gauge the estimated cost is based on the number of bedrooms.

 

Two bedrooms

A two bedroom house in Sydney is reported to cost between $276,000 and $864,000 for a new construction, based on an average size of approximately 120 square metres. This price variation also reflects different budgets and preferences.

 

Three bedrooms

Three bedroom homes remain a popular choice for new builds, balancing everyday living with room to adapt as the needs of a family change. A typical three-bedroom newly built house in Sydney costs between $402,500 and $1.26 million to construct in 2026. This is based on the average price per square metre, representing the standard three-bedroom house size of 175 square metres.

 

Four bedrooms

Over 21,000 new homes were constructed in Sydney in 2024, according to the latest research from RLB, with large houses the most popular for new builds. Four-bedroom layouts suit growing households, providing shared spaces and individual privacy that suits the modern family.

Four-bedroom homes are a popular choice in Sydney for a newly built house. The cost can vary between $598,000 to $1.8 million. For a home of this size, standard inclusions would assume multiple living spaces and bathrooms.

 

Five bedrooms

Large five-bedroom homes are increasingly common across Sydney, particularly in outer suburban areas with more substantial lot sizes. Many people may prefer a large home to accommodate for multigenerational living or home office requirements.

Recent data reveals that a five-bedroom home may cost anywhere between $690,000 to $2.16 million based on a house size of 300 square metres. 

 

How does the cost of a house vary by build type?

A successful build is the result of careful planning and paying attention to the factors that affect a build process and pricing. A clear scope of works from the planning stage through to lock up ensures a successful and happy new home. Moving from budget to luxury builds, costs increase as specifications rise, customisation becomes prevalent, and council and site challenges are ascertained.

Building a house on a budget

Building on a budget? We can offer a range of options and advice gained through our 48 years of home building experience. A budget home build in Sydney will prioritise cost efficiency through standardised home designs, smaller floor areas and standard material selections. Costs can be minimised with less site works and are more likely to be viable on flat, serviced sites with straightforward planning controls - our consultants can advise you on these factors.

Costs of a standard build

Design choices are rarely just about aesthetics, and instead, those choices made in the planning phase to achieve a standard home build are the ones that help maintain an achievable costing. A standard home build represents the mid-range of Sydney’s residential construction market and balances cost, durability, and design flexibility. 

This category of build reflects the typical mid range cost of building a new house in Sydney in 2026, with costs in the range of the $5,000 per square metre price.

How much does a luxury new house build cost?

Luxury homes are those where every element of design and living has been considered, creating a space that feels both refined and comfortable. RLB estimates that high-end residential builds can exceed $7,000 per square metre, particularly for projects that involve challenging sites, multi-level structures, or extensive planning and design controls.

Luxury builds provide a premium new house, one that is tailored to the people who live in them and their lifestyle, with the price reflecting higher professional fees and extensive customisation.

What other factors affect the cost of a new build?

Site costs

Site costs for a new build often represent one of the more unpredictable components of building a house in Sydney. Sloping blocks, poor soil conditions, rock excavation, demolitions and restricted site access can increase construction cost before work on the home itself begins. 

So how much does it cost to build a house including site costs? Speak to our team to get an accurate costing for your land. Remember that site costs can sometimes be governed by council in established suburbs. Think tree protection, traffic management and stormwater solutions - these can all increase build prices. It can also vary the price between individual houses to a significant degree, meaning that the cost of a house is not always entirely predictable.

Land costs

Sydney is one of the most expensive cities in the world to purchase property, according to the Economist Intelligence Unit Report. That means that land within Sydney’s premium housing market is frequently the most significant cost of building a home in 2026. A large financial output is necessary, which can exceed the cost of construction, and this influences the decisions around house size, design and level of finish. High land values can also impact holding costs and capacity to borrow for the build, indirectly raising the overall costs of a new build.

What is the impact of permits and approvals?

Building in Sydney comes with unique considerations. Council permits and approvals both affect the timeline and the cost of building a new home. These can include council planning approvals, mandatory construction certificates, BASIX requirements, and consultant reports all add professional fees to the build. In some circumstances, homes that trigger design review panels, variations, or neighbour objections typically incur higher approval and holding costs. 

These concerns make the guidance from Rawson Homes invaluable, along with the technical expertise and design flair on offer.

How do design and finish choices affect pricing?

Clients are often surprised by how interconnected design, materials and construction can be in the process and timeline of constructing a home. Design choices play a major role in determining the final price. Complex layouts and premium finishes increase material quantities, labour hours, and coordination across trades, all of which impact the pricing of a new house in Sydney. A clear scope from the outset helps reduce uncertainty.

Market conditions

House market conditions directly influence the cost of building a new house through the rates of labour, material pricing and the availability of builders. When demand for construction is high, the competition for trades pushes build prices upward and extends the date of completion of your new build. Other factors such as disruptions to supply chains can further affect new build costs.These conditions make timing an important consideration when planning a home build.

Contingencies

A contingency is a dedicated budget that keeps a project on track when the unexpected makes an unscheduled appearance. When constructing a new home, a contingency is vital to protect homeowners from cost overruns during the build. Unexpected site issues, changes in regulations or council requirements, and client-driven variations are common in new home builds which can increase the price.

Industry experts recommend a contingency provision of 5-10 per cent of the construction costs as a buffer to reduce the financial risk and best prepare for a successful build.
