Sloping block builders Sydney
Sloping blocks don’t mean your dream has to go downhill.
Many other builders see sloping blocks as too complex or too costly. At Icon Homes, we see a challenge, and we’re ready to take it on.
As well as enjoying the challenge, we love seeing homeowners realise their dreams. Building on a sloping site allows for custom homes that respond to the land, unlocking natural light, natural ventilation, and unique design features that simply aren’t possible on a flat block.
Whether you’re working with a slight slope or a steep block, we believe building on a sloping block should feel like an advantage, not a limitation.
Living on Sydney’s Northern Beaches or on the North Shore means that sloping land is relatively common. While some people see these as a disadvantage, we see potential for elevated views, capturing the natural landscape in all its beauty.
As a specialist sloping block builder, we manage the entire process from early planning and house plans through to construction and final handover. We work closely with you to create a sloping block home that suits your lifestyle, your land, and your long-term value goals, while giving you a clear understanding of site costs, budget, and possibilities.
After working with sites like these for over a decade, we’re well-versed in building on slopes and making every square metre of your block count.
The types of sloping blocks
1. Slight slope (750- 1250mm)
For slight slopes between 750 and 1250mm, we use the ‘cut and fill’ technique. This allows the ground floor to remain at the same level, just as it would on a flat block. We then use retaining walls to support the ‘cut’ and dropped edge beam to support the ‘fill’. Although it’s a slight slope, this still requires additional excavation and possibly soil removal.
2. Moderate slope (1250- 2500mm)
Moderate slopes also require retaining walls and dropped edge beams for sections of the slabs. We will need to build internal steps inside the home, as this allows the floor plan to follow the natural contour of the block. One big advantage of moderate slopes is that they provide increased ceiling height, making the home feel bigger and brighter.
3. Steep slope (Greater than 2500mm)
Slopes greater than 2500mm mean that the best course of action is a split-level home. This is far from a disadvantage, as split-level homes are typically as unique as the blocks they’re built on! Often, external walls will double as structural supports, and sections of the flooring slab will be constructed as suspended concrete slabs.
Frequently Asked Questions
Is a sloping block a disadvantage?
To us, not at all! There are many advantages to sloping blocks, such as showcasing views and allowing for creativity. Don’t be disheartened if your block isn’t perfectly flat, as it could end up being your home’s biggest asset.
What is a split-level home?
A split-level home is designed to follow the natural slope of the land, creating a stepped layout across multiple levels instead of relying on a single-level slab. This approach is common in sloping-block home designs, as it works with sloping land or steep slopes to reduce excavation, retaining walls, and fill required, while allowing the home to sit more naturally within the landscape.
Split-level home designs also improve flow between spaces, maximise natural light and ventilation, and can help manage site costs and construction complexity. This means your result is a functional, well-designed home that suits the block and delivers long-term value.
Will you be able to build on my sloping block?
Every block is different, so this will depend on a variety of factors. We offer free site assessments to determine if we can work on your block, so please get in touch to organise your assessment.
What are some challenges that sloping blocks can present?
No sloping block is without its potential challenges. Possibilities include land slips, tree removal, earthworks, getting materials on site, and issues with retaining walls, drainage, and landscaping. However, with the right planning and experienced builders, we carefully manage these challenges throughout each stage of the process.
Does building on a sloping block cost more than on a flat block?
Not necessarily. A sloping block typically requires building a split-level home, but this doesn’t incur additional costs on its own. At Icon Homes, we provide provisional allowances (PAs) to keep the process transparent and flexible, giving you a clear understanding of where your budget is going.
