Walk a new home site in Victoria today and something is missing from the service trench. There is no gas line running to a meter box on the side wall, no flue climbing through the roof above the cooktop, no second utility to coordinate against the electrical work. For most of a century the gas connection was a fixed point that the rest of the house was planned around. It is now being designed out, and the consequences reach a long way past the kitchen.
It is tempting to read this as a compliance subtraction, one more box on the energy report. Treated that way, it produces flat, all-electric houses that feel like a gas home with the burners swapped out. Treated as a design reset, the same constraint frees the plan, the facade and the way a home performs. The difference is decided at concept stage, not at certification.
The mandate, briefly
From 1 January 2024, new Victorian homes and residential subdivisions that need a planning permit can only connect to all-electric networks. A permit will not be granted to run reticulated natural gas to a new dwelling or apartment development. The state has tied the move to running costs and emissions, pointing to savings of around a thousand dollars a year on energy bills, and more again where a home pairs all-electric appliances with rooftop solar. A further phase of building electrification regulations is flagged from 2027. Other jurisdictions are watching. For anyone designing now, the trajectory is settled enough to lead with rather than resist.
The kitchen changes first
Induction replaces the gas cooktop, and with it goes the flue and the gas run. That sounds minor until you draw it. The cooktop is no longer tethered to an external wall for a flue or to a service route for a pipe, so the island can sit where the plan wants it rather than where the gas allowed it. Downdraft extraction becomes a genuine option, which keeps sightlines clean in open kitchens that used to be dominated by an overhead canopy. The trade is electrical: induction wants dedicated circuits and switchboard capacity, and that has to be resolved early, not discovered on site.
Heat without a flame
Space heating shifts to reverse-cycle systems and, increasingly, to hydronic loops driven by a heat pump rather than a gas boiler. In-slab hydronic from a heat pump gives the quiet, even warmth designers like, but it changes the brief: the building envelope has to do more work, because a heat pump rewards good insulation and airtightness and punishes a leaky plan. Plant location becomes an acoustic and visual decision too. Heat pumps and hot-water units make noise and need air, so screening, setbacks from bedrooms and boundary distances belong on the early drawings, not in a late services coordination scramble.
The services worth designing for
Take gas out and the electrical side grows. Bigger switchboards, rooftop solar, battery storage and EV charging all want space, sightlines and cable routes resolved at concept. The smart move on a staged budget is to design the home all-electric ready: pull in the conduits, size the board and leave the roof and garage prepared, so a battery or a charger is a later upgrade rather than a later renovation. A home detailed this way absorbs the 2027 standards without a redesign.
The model already exists
Architects do not have to imagine the post-gas home, because it has been built and lived in for years. Nightingale Housing, the not-for-profit model that grew out of Breathe Architecture in Melbourne, has delivered fossil-fuel-free, all-electric apartments since its first project, Nightingale 1, with rooftop solar, an embedded green-power network and no gas anywhere in the building. What stands out for designers is not the technology but the discipline. The buildings work because a tight envelope, energy efficiency and an honest, reduced material palette were the starting point rather than an offset bolted on at the end. The mandate is largely asking the rest of the market to catch up to what the better projects were already choosing to do.
Where gas stays in the picture
None of this erases gas from the wider housing stock. Existing homes keep their connections and electrify in stages, an appliance at a time. Regional and off-grid properties beyond the reticulated network still run on bottled LPG for cooking and heating, and outdoor living, from alfresco kitchens to fire features, continues to lean on it. For homeowners and designers trying to make sense of how gas in the home is changing, and where bottled supply still fits once a mains connection comes off the table, a plain comparison of LPG and natural gas is a useful place to start a conversation with a client.
A better house, not just a compliant one
The homes that will age well out of this shift are not the ones that merely passed. They are the ones where the architect used the freed-up plan, the cleaner facade and the coherence of an electric-plus-solar system as the actual design material. Remove indoor combustion and the air is healthier. Remove the gas meter and the wall is quieter. Plan the electrical load properly and the house is ready for whatever the grid and the regulations do next. The gas connection was a constraint we stopped noticing. Designing without it is a chance to notice what the home could be instead.
