Why Build A Second Storey/First Floor?

Second storey extensions, also known as first floor additions, are an excellent way to add space and value to your home without compromising your lifestyle.

They have become increasingly popular among Sydney homeowners, particularly growing families or those who need extra space but want to avoid the hassle and cost of relocating.

In high-cost areas like Sydney, building up with a second-storey extension is often a more affordable and convenient alternative to purchasing a new home.

Avoid the Costs of Moving


Save on relocation expenses and stay in the neighbourhood you love by expanding your existing home instead of moving.

Maximise Space Without Losing Yard Area


A second-storey extension lets you add valuable living space to suit your evolving lifestyle needs without sacrificing your backyard, preserving outdoor areas for relaxation or play.

Accommodate a Growing Family


As your family grows, a second-storey extension provides extra bedrooms, bathrooms, or living areas to meet your changing needs.

Increase Your Home’s Value


Adding a second storey significantly boosts your property’s market value, making it a smart investment for future resale.

Customise Your Dream Layout


With a second storey, you can reimagine your home’s layout, creating tailored spaces that perfectly fit your lifestyle and preferences. You can even elevate your home to take advantage of scenic views and natural light, creating a brighter, more inviting living space.

5/5

Next Story completed our build in Forestville. The team were outstanding. The listened to what we wanted, they were respectful and the work was high-quality. The attention to detail really stood out from builders we have worked with previously. Even better, they were fast and we stayed living here during the build. Our neighbours could not believe the transformation. Highly recommend.

My wife and I were looking at new houses but were having to compromise with our budget. Spoke with Tom at Next Storey and opted for the second storey extension- The bank valuation is back. Best decision I’ve made
