Custom home builder in Castle Hill
Castle Hill is one of Sydney's most in-demand suburban locations: well-serviced, central to the Hills District, and home to some of the most active knockdown rebuild and dual occupancy activity in Greater Sydney. Refined Group specialises in exactly this kind of work: replacing ageing homes with beautifully designed, architecturally considered custom builds.
What we build in Castle Hill
Custom homes
Every home we design and build in Castle Hill is tailored to your block, your brief and your lifestyle. We don't work from fixed plans. You work directly with our Director from the first conversation through to handover. Whether you're starting from scratch or replacing an existing home, we'll guide you through design, approvals and construction as a single point of contact.
Knockdown rebuilds
Castle Hill has large residential blocks, strong infrastructure, and a thriving community, making it well-suited to knockdown rebuild projects. We manage the entire process: demolition, design, council approvals and construction. You don’t need to coordinate multiple contractors.
Pools
We integrate pool design into the home design process from day one, not as an afterthought. Every Refined Group project in Castle Hill considers how the pool, home and outdoor spaces interact. The result is a more cohesive finished product and a smoother build process.
Landscaping & gardens
Our landscaping team designs and constructs outdoor spaces that complement your home and suit the character of Castle Hill. From structural landscaping and paving through to planting and lighting, we handle it all under one contract.
