How much will my house extension cost?

Refresh has carried out home extensions ranging from $67,000 - $200,000+*. Same-level extensions are generally the most affordable option, however, second-storey additions are sometimes the best option for those who have little room to extend outward. Refresh can also support you with basement excavations/renovations. Refresh will design your project with your budget in mind and can advise you on ways to keep costs down. 

*Costs are rough estimates and are subject to change - GST is not included unless otherwise stated. For a fixed-quote accurate to your specific project, please consult your local Refresh Renovations Consultant. 

Will Refresh take care of any required council consents?

Home extension work will need to be signed off by a local certifying authority. Depending on a range of factors, this may be through a Development Application or a Complying Development Certification. Your Refresh Renovations Consultant will take care of this process for you, ensuring all work complies with local consents and regulations. For further guidance, please consult your Renovation Consultant. 

What are some important considerations for home extensions in Sydney?

When renovating in Sydney, it’s important to be wary of the materials you use. Masonry, concrete and steel are great termite-resistant materials. If your property is on bush-fire-prone land, you will also need to ensure you are using fire-rated building materials and sealants. To find out if your property is on bush-fire-prone land, visit or consult your RTenovation Consultant.
