GALSTON

This home renovation transformed a 1950s property with modern kitchen design, micro-cement bathrooms, and updated layout. Premium finishes and new driveway enhanced functionality while complementing the suburb's family-friendly atmosphere and leafy residential character.

CUSTOM EXTENSIONS IN GALSTON

This transformative project breathed new life into a rundown 1950s weatherboard house, seamlessly blending its historic charm with contemporary flair. Extensive structural modifications facilitated significant alterations to the floor plan, enhancing spatial flow and functionality. The renovation showcased two meticulously crafted bathrooms adorned with Venetian micro-cement rendered surfaces, embodying modern sophistication.

A redesigned kitchen, complete with an inviting island bench, became the heart of the home. The addition of a new driveway enhanced accessibility and curb appeal, while comprehensive updates to both internal and external surfaces revitalized the property’s aesthetic appeal. This project exemplifies the seamless integration of bespoke design and meticulous craftsmanship, resulting in a home that harmoniously balances heritage charm with contemporary living.
