How your home design becomes yours
Speak with one of our New Home Consultants and they’ll walk you through how we take a home design from the catalogue to something distinctly yours. It’s 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, creating each home design room by room before a slab is poured. Room proportions, window placement, structural elements: all considered before construction begins.
- Each home design incorporates hundreds of hours of professional input. Light, flow, day-to-day usability, buildability: all worked through, so the finished home works as well as it looks.
- Designs are reviewed each year against what’s working locally and what’s shifting globally, from energy-efficient features to contemporary facade styling and open-plan living layouts.
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 South Australia you’re building. Local factors like soil conditions, slope, and council requirements across Adelaide and regional SA 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 first step is a conversation with a New Home Consultant, who’ll walk you through costs and inclusions against your specific situation.
- What can I customise in a G.J. Gardner home design?
Your home design gives you flexibility across the whole brief. You can adjust the floor plan layout, room sizes, and facade style. Internal finishes are yours too: benchtops, cabinetry, flooring, and tiles, plus fixtures and fittings. You can configure outdoor living, garage placement, and energy efficiency features. Every change runs through a structured process, so nothing falls through the cracks.
- How long does it take to customise an existing home design?
Two to four weeks is typical, depending on how far you take it. Straightforward adjustments like room sizing or finish selections sit at the shorter end, while structural modifications or anything requiring council approval can push the timeline out. Your G.J. Gardner team runs the schedule and keeps you across every stage.
- 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 for my area? Can I see 3D renders of my customised design before I commit? And what happens if I want to change something after the design is signed off? Having these ready helps you get the most from your time with the team.
