MONA VALE

This fully renovated 1950s home features a thoughtful new layout, a beautiful modern kitchen, and elegant bathrooms. Fresh interior updates and a newly finished driveway add both comfort and impressive curb appeal.

CUSTOM EXTENSIONS IN MONA VALE

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.
