Every new home in Australia needs an energy rating certificate now, and that's a good thing — but I see plenty of builds that scrape over the line and miss the bigger opportunity. The energy rating is the floor, not the ceiling. The smart move is to think about thermal performance, water and energy at the design stage, before plans get locked in, because retrofitting any of this after the fact is painful and expensive.
On the Gold Coast we deal with humidity, hot summers and a sun that's brutal from the west most afternoons. That dictates orientation more than people realise. Bedrooms and breakfast nooks do well facing east — you get the morning light without baking by midday. Kitchens and main living spaces do well facing north, with deep eaves so the high summer sun is shaded but the lower winter sun still streams in. The west side is the one I'm most cautious about. Big west-facing windows with no shading become a heater you can't switch off, and your power bill knows about it.
Beyond orientation, there's the building envelope — walls, roof, floors and insulation. Higher-rated insulation, decent glazing (double-glazing where it matters), and good cross-ventilation paths through the home will do more for your comfort than another split-system ever will. Add a verandah on the right side and you've effectively extended your living space outdoors for nine months of the year, which is the whole point of being on the coast in the first place.
A lifestyle focused custom new home isn't just about how the rooms look — it's about how they feel at 3pm in February. If you want to go further, this is also the moment to talk solar, rainwater capture, recycled materials and water-efficient fixtures. Don't bolt them on later. Bake them into the design.
