At 32 Degrees Building, we specialise in custom ground floor extensions that complement your existing home, maximise available space and create a seamless connection between old and new.
Our team can help you explore what’s achievable for your property, taking into consideration your available land, existing home, budget and local planning requirements.
The cost of a ground floor extension in Sydney depends on the size, design, structural requirements and level of finishes involved.
Unlike our first floor addition packages, ground floor extensions are custom-designed to suit your existing home, available land and individual requirements.
Factors that can influence the overall construction cost include:
- Size and complexity of the extension
- Structural modifications to your existing home
- Kitchen, bathroom and laundry installations
- Materials, fixtures and finishes
- Site access, ground conditions and drainage requirements
At 32 Degrees Building, we specialise in ground floor extensions and major renovations with a minimum construction budget of $150,000.
For a detailed Build Cost Estimate tailored to your property and proposed scope of works, we recommend booking a consultation with our builder.
The construction timeframe for a ground floor extension depends on the size, complexity and scope of works involved.
Unlike our first floor addition packages, ground floor extensions are custom-designed, meaning construction timeframes vary from project to project.
Factors that may influence the building timeframe include structural modifications, kitchen and bathroom installations, site access and the extent of renovations to your existing home.
Before construction begins, we’ll provide an estimated building timeframe based on your specific project, so you know what to expect.
The pre-construction stage, which includes design, engineering, documentation and council or certifier approvals, typically takes 4–6 months and is additional to the construction timeframe.
At 32 Degrees Building, we carefully plan and coordinate each stage to minimise delays and disruption to your family.
Not necessarily! Depending on the scope of your ground floor extension, you may be able to remain living in your home during some or all of the construction process.
However, temporary relocation may be required during certain stages, particularly where structural modifications, major internal renovations or disruptions to essential services are involved.
The need for relocation and its duration will depend on your home’s layout, the extent of the building works and site safety requirements.
Safety is our top priority, and any potential risks, temporary access restrictions or service interruptions will be clearly communicated throughout the process.
Our experienced team will discuss these arrangements with you before construction begins, helping you plan ahead and minimise disruption to your everyday life.
Our goal is to make the building process as smooth and manageable as possible for your family.
Yes, most ground floor extensions in Sydney require building approval before construction can begin.
Depending on your property, proposed design and local planning requirements, your extension may be approved through one of two pathways:
- Complying Development Certificate (CDC): A streamlined approval process through a registered certifier, provided your extension meets the relevant planning and building requirements.
- Development Application (DA): Submitted to your local council for assessment when your proposed extension doesn’t meet CDC requirements or requires a more detailed planning assessment.
Factors such as setbacks, site coverage, heritage restrictions, flood zones and bushfire requirements can influence which approval pathway is available.
At 32 Degrees Building, we manage the design, planning, engineering and approval process as part of our pre-construction services, helping you navigate the requirements without the stress of coordinating everything yourself.
The pre-construction stage typically takes 4–6 months, depending on your project and approval requirements.
Yes. Ground floor extensions are subject to planning and building requirements, which can vary depending on your property, local council and proposed design.
Factors such as setbacks, site coverage, floor space ratios, heritage restrictions and flood zoning may influence what you can build.
Our team can guide you through the relevant planning and approval process, including whether your project may qualify for a Complying Development Certificate (CDC) or require a Development Application (DA) and Construction Certificate (CC).
