When you’ve got land to use, a ground floor extension is a great option for you. This is the ideal way to “build out” on your house by adding additional outdoor or indoor living space without altering the street appearance, and means you can avoid stairs if you don’t want them.
Most of our clients still live in their homes while their extension is going on and we will do our absolute best to maximise your family’s safety and minimise mess, dust and the intrusion of having a building site in your backyard.

Elevate everyday living with custom house extensions
A ground floor extension is a smart way to expand your home without the structural challenges, relocation or height limits of an upper storey.

At 32 Degrees Building, we manage every stage of your project, from design and planning to construction and compliance.

Built with precision and quality materials, our extensions are durable, functional and made to enhance everyday living.
FAQs
Do we need to move out during construction?
With a ground floor extension, it may be advised that you move out during the construction. During this time, power may be disconnected and areas of your home will be inaccessible. Our team will advise you whether it’s safe to return home while we finish the rest of the build.
Before work begins, we’ll clearly outline what to expect, including any safety considerations. Your site supervisor will provide regular updates throughout the project and ensure you’re aware of key milestones and timelines.
How much do ground-floor extensions cost?
The total cost depends on project scale and the materials used. Some extensions involve full kitchen, laundry or open-plan living upgrades, while others may focus on adding a few extra bedrooms or a living area. As every home and project is unique, the best way to get an accurate estimate is to book an initial consultation with our team.
What type of ground floor extension can I have?
A ground floor extension can significantly enhance and expand your existing living spaces. Whether you’re looking to add a larger kitchen, laundry or dining area, or seeking open-plan living, this renovation option offers flexibility and value. A ground floor extension can also introduce:
- Additional bedrooms or guest rooms
- Spacious family or living areas
- Dedicated home office or study
- Practical utility or mudroom
- Home theatre or media room
- Alfresco or outdoor entertaining spaces
- Extra storage solutions
We will work with you to design a layout that maximises usable space and seamlessly integrates with the style and flow of your existing home.
How can I request a quote for a house extension?
Fill out our online questionnaire with key details about your project, including preferred materials, budget and timeline. If you have existing plans or approvals (DA/CC/CDC), you can upload them along with any supporting documents. Once we’ve reviewed your submission, our builder will contact you to discuss your requirements and provide a detailed quote.
Are there any council regulations I should be aware of?
Yes, council regulations are a key part of any extension project, whether you’re working on a first floor or second storey addition. This is especially crucial if your property is subject to zoning rules or a heritage overlay. Rest assured, our team will help you manage the approval process so your project progresses smoothly and without setbacks.
