Architect designed. Refined built.
We collaborate with some of Sydney’s great architects, and the best results come when we’re involved early. Bringing the builder into the design conversation from the start means buildability, budget and the realities of your site shape the plans as they’re drawn, not after. It also lets the home, pool and landscape be resolved as one design rather than three afterthoughts.
Already have an architect, or plans in hand? We’re just as comfortable joining part-way through design or building faithfully from completed drawings. Starting from scratch? We’ll introduce you to architects whose work we trust.
Either way, you deal directly with our director from the first conversation to handover.
One contract. Home, pool and gardens.
Refined Group exists because of a gap our director, Charbel Simon, kept seeing: homes designed with no thought for the landscape they sit in, and gardens bolted on at the end. He began his career in landscape design and construction before moving into building, and founded Refined Group to close that gap.
Because your home, pool and gardens are designed and built by one team under one contract, you avoid the delays, cost blow-outs and finger-pointing that come with juggling separate builders, pool contractors and landscapers.
What we build
Custom homes
High-quality custom homes across the Hills District and North Shore: Kellyville, Castle Hill, Westleigh, Wahroonga, Mosman and beyond. We limit the number of projects we take on so every build receives the director’s personal attention, and we manage the entire process from site preparation to final landscaping.
Knock-down rebuilds
Love your street but not your house? A knock-down rebuild replaces an ageing home with a brand-new custom build on the block you already own, often better value than a major renovation. With your plans in hand, we manage the demolition, site preparation and construction under one experienced team. We also take on select dual-occupancy projects. See our Seven Hills dual occupancy, or ask us whether your block suits one.
Renovations & outdoor projects
We selectively take on renovation projects, especially those focused on outdoor spaces. If you’re looking to enhance your property with a pool, landscaping or home extensions, our expertise in these areas makes us an ideal choice.
How it works
- 01
An intro call with our director
A no-pressure conversation about your project, your site and whether we’re the right fit. Nothing moves forward until you’re comfortable.
- 02
Design & detailed quote
We work from your architect’s plans, or help you get the design right first. Once the brief and plans are in place, you receive a detailed quote.
- 03
One contract
Home, pool and gardens scoped and coordinated together. One contract, one point of contact, no juggling separate trades.
- 04
Build & handover
A custom home typically takes 12–18 months from contract to handover, with our director directly involved throughout.

Where we build
We’re based in Bella Vista and build throughout Sydney’s Hills District and Upper North Shore, in suburbs like Kellyville, Castle Hill, Baulkham Hills, Winston Hills, Cherrybrook, Dural, Wahroonga, Turramurra, St Ives, Pennant Hills, Westleigh and Mosman. Working close to home means we know the local councils, the blocks and the builders’ challenges in these areas. If your suburb isn’t listed, get in touch. We may still be able to help.
Common questions
-
Where do we start?
Reach out and we’ll set up an introduction call with our Director. We’ll talk through your project, understand what you’re looking for, and advise on next steps. It’s a no-pressure conversation, just about making sure we’re the right fit before anything moves forward.
-
How we differ from a project home builder?
Project home builders work from fixed plans and fixed finishes. We don’t. Every project is designed around you: your site, your brief, your preferences. You work directly with our Director from start to finish, and we handle everything under one contract, whether that’s just the home or the full package including pool and landscaping.
-
Do you work with architects?
Yes. If you already have an architect or are part way through design, we’re happy to work alongside them. We also build from completed plans and can help connect you with design professionals if you’re starting from scratch.
-
How long does a build take?
Timelines depend on size and complexity. A custom home typically takes 12–18 months from contract to handover, not including the design and approval phase. We’ll give you a clear timeline during the quoting process.
