How your home design becomes yours

Sit down with one of our New Homes Consultants and they’ll walk you through our approach to custom home design: a structured process, considered at every step, and shaped around your block, your taste, and the way your household actually lives.

  • Our building designers work in detailed 3D, so you can see every room, sightline, and structural choice before a slab is poured. Spatial flow, livability, and the way each space connects: all considered before the home gets built.
  • Each home design is refined long before it ever reaches you. Light, flow, day-to-day usability, buildability: all worked through by professionals, so the plan works as well in practice as it does on screen.
  • Designs are reviewed each year against what’s working locally and what’s shifting globally in new home design, so the home you build today still feels current a decade in.

FAQs

  • How much does it cost to build a custom home?

    Cost depends on the home design you choose, your block, the finishes you select, and where in Sydney you’re building. Local conditions like soil type, slope, and council requirements all play a role. G.J. Gardner Homes works on fixed-price contracts, so once your design is finalised, the number doesn’t move on you. Your initial consultation with a New Homes Consultant is the best place to walk through realistic numbers for your specific budget and block.

  • What can I customise in a G.J. Gardner home design?

    You have flexibility across the whole brief. Floor plan layout, room sizes, and facade style. Internal finishes are yours too: benchtops, cabinetry, flooring, tiles, fixtures, and fittings. Outdoor living, garage configuration, and energy efficiency features can also be tailored. Every change runs through a structured process with your local team, so nothing falls through the cracks during the design phase.

  • How long does it take to customise an existing home design?

    Two to four weeks is typical, depending on how far you take it. Structural modifications or anything that depends on council approval can push the timeline out. Your G.J. Gardner team runs the schedule throughout and keeps you across every stage, so there are no surprises.

  • What questions should I ask when customising an existing home design?

    Walking in prepared makes a real difference. Useful questions: What’s included in the base price? What can and can’t be changed structurally? How will my changes affect the build timeline? What energy efficiency options are available in my area? Can I see 3D renders of my customised design before approval? And what happens if I want to change something after the design is signed off? You can also review our list of essential questions to ask any builder. Having these ready puts you in control of the conversation from the start.

  • How do I get started?
