Looking for home extensions in Sydney to add more space to your home? This family in Doonside faced the challenge of outgrowing their small three-bedroom home after over 20 years. With just one bathroom, a compact living room, and a combined kitchen and dining area, they needed a first-floor home extension that would accommodate their growing needs without the hassle of moving.
That’s where Apex Alterations & Additions, Sydney’s home additions specialists, stepped in to transform their home into a spacious six-bedroom, two-bathroom residence.
The Challenge

The homeowners loved their Doonside neighbourhood, but their existing home no longer met their needs. Limited space and only one bathroom made daily life increasingly inconvenient. Moving wasn’t an option, so they sought a first-floor home addition to increase their living space while maintaining the original structure.
