How much does it cost to build a split level home?
When considering building a new home, the layout and design of the land play a crucial role in determining the type of dwelling that will work best.
For properties on sloping sites or where views are a priority, a split-level home might be the most practical choice. Split-level homes are designed to integrate with the natural landscape, offering both aesthetic and functional benefits.
While they tend to come with a higher price tag than single-level homes due to the more complex structural requirements, the advantages can make them well worth the investment for certain site conditions.

Is a split-level house right for you?
A split-level house design works by dividing the home into multiple levels, each aligned with the land’s slope.
A split-level home offers many benefits, especially for properties with unique site features such as slopes or scenic views.
1. Maximising Views
One of the primary advantages of a split-level design is its ability to take full advantage of a site’s views. Whether it’s a hilltop vista, a coastal outlook, or a panoramic cityscape, the stepped levels of a split-level home can position different rooms at varying heights to capture the best views. The design can place living areas on elevated levels for optimal views, while lower levels might be more private, serving as bedrooms, offices, or entertainment areas.
2. Integrating with the Land’s Natural Contours
Split-level homes are ideal for sloping blocks, as they allow the house to follow the land’s natural incline – whether the site requires an upward or downward sloping design. This approach reduces the need for expensive and extensive excavation to level the ground, which can be both costly and environmentally disruptive. By building with the lay of the land, these homes preserve the site’s natural topography while providing functional and well-considered living spaces.
3. Improved Natural Light and Ventilation
The tiered design of split-level homes allows for better natural light and airflow, as different levels of the home will have access to windows and external spaces that a single-level home might lack. Building with the land’s natural slope means less need for extensive earthworks.
If a home is built without a split-level design on a sloping site, builders often have to perform a large site cut to create a flat building platform. This typically requires massive retaining walls, which not only add considerable cost but can also block views and reduce natural light.
By following the land’s contours, a split-level home design can preserve both sunlight and sightlines, creating a more open, comfortable, and visually connected home.
4. Better Use of Space
Split-level homes make more efficient use of available space by distributing functions across multiple levels. For example, the lower levels can be designed for less frequently used areas such as garages, home offices, or entertainment rooms, while the higher levels focus on living and sleeping areas. The result is a more spacious home that feels well-organised and adaptable. For many, this flexibility plays a key role in achieving a practical version of their dream home, particularly on sites where flat designs may compromise layout or privacy.

Are split level homes cheaper to build?
However, as with any complex build, a split-level home is typically more expensive to construct. The additional cost stems from several factors, making it an investment that suits those with the right site and a desire for a unique home that maximises the land’s potential. Here are the main factors that influence cost:
1. Site Conditions
The site’s slope, accessibility, and size all play a significant role in determining the cost. A steeper slope will require more custom work to ensure the home is stable, and the foundation need to be engineered specifically for the site. Additionally, if the site is difficult to access, transporting materials and equipment around the site can add to the cost.
2. Design Complexity
The more intricate the design, the more costly the project will be. Custom designs, which are typical for split-level homes, require skilled designers and engineers to ensure that the floor plan works with the site’s natural features while maintaining structural integrity. More complex designs will also require additional time and expertise from tradespeople.
3. Foundation and Structural Work
Split-level homes require specialised foundations to accommodate the varying levels of the structure. This might involve more complex structural elements, such as retaining walls, additional drainage systems, or reinforced footings. The foundation work for a split-level home is usually more costly than that of a single-level home, as it requires more material and labour.
4. Materials and Finishes
The materials used for a split-level home will also impact costs. Depending on the design and desired finishes, there may be a higher demand for premium materials, whether it’s for structural components, finishes, or additional features. The use of high-end materials such as large windows, custom stairs, and modern, energy-efficient systems can further increase the overall price.
5. Labour and Time
Given the complexity of the construction, split-level homes tend to take longer to build, which can result in higher labour costs. More skilled tradespeople will be needed for both structural and finish work, and the time involved can increase depending on the site’s conditions.

How much to build a split level home in Geelong?
While specific costs for building a split-level home can vary widely depending on the region, site conditions, and design specifics, some general cost factors can be considered. For instance, looking at general construction costs in regions like Geelong, where prices are more typical of medium-density urban developments, it can be assumed that split-level homes could cost anywhere from ten to 30 per cent more than a single-storey home.
However, it’s important to remember that the costs can vary significantly depending on the site’s complexity. Sloping sites with severe inclines or those requiring additional earthworks could push costs even higher. In contrast, a more moderate slope may not add as much to the price tag.
Ultimately, building a split-level home is a thoughtful decision that should be based on the specifics of the site and the lifestyle it can offer. Whether driven by the desire for exceptional views, a more functional layout, or simply the appeal of working with the land’s natural form, a split-level home can prove to be a functional and wise investment for the long term.

How Hamlan can help
Building a home on a sloping site comes with complexities that not every builder is equipped to manage. With over 40 years of experience delivering homes across Geelong and the Surf Coast, Hamlan has developed a deep understanding of how to design and construct homes that work with the natural lay of the land.
Hamlan’s Aspect Range offers a series of pre-designed split-level homes tailored to suit a range of slopes – removing much of the guesswork and streamlining the process. From sites with subtle gradients to steeper inclines, these designs are created to maximise space, light, and functionality while addressing practical considerations like drainage, access, and energy efficiency.
Hamlan’s approach balances design intent with site-specific performance, ensuring each home sits comfortably in its environment. Our in-house expertise covers everything from stormwater management and retaining wall planning to passive solar design principles and the integration of rooftop solar storage systems.
Our team also works closely with each client to select or adapt the right split-level design, one that reflects the site’s character while meeting the practical needs of modern living.
