Former Lawyer Transforms Sydney Terrace into Off-Grid Sustainable Haven
Michael Mobbs, a 75-year-old former lawyer turned gardener, has achieved remarkable financial and environmental savings by living completely off-grid in his Chippendale terrace home. Purchased for $23,000 in 1978, this three-bedroom property underwent a radical transformation in 1996 when Mobbs decided to disconnect from all municipal utilities.
Radical Renovation Creates Self-Sufficient Home
During renovations nearly three decades ago, Mobbs installed multiple solar panels on his roof to generate electricity and implemented a sophisticated water management system. This includes a rainwater collection tank that filters fresh drinking water and an underground wastewater recycling system that processes more than one million litres annually.
The recycling system handles water from showers, dishwashers, and toilets, sterilising it underground before repurposing it for flushing toilets, garden irrigation, and laundry. This comprehensive approach has eliminated Mobbs' dependence on Sydney's water and sewage networks.
Financial Savings and Philosophical Freedom
Mobbs estimates his off-grid lifestyle saves approximately $3,500 annually on utility costs. "There's a growing distancing by property and apartment owners from fixed charges and energy and water costs," he explained to the Daily Mail. "Because I've been doing this for 30 years, the idea has credibility with people who are deciding to put their own money into copying."
The former environmental consultant, who worked for nearly two decades as a lawyer before his career shift, finds philosophical satisfaction in his independence. "Being off grid I feel free, safer from gaslighting governments, companies and all those who greenwash," he stated.
Family Adjustments and Public Interest
The decision to renovate initially raised concerns from Mobbs' then-wife and their two young children, aged six and ten at the time. "My then-wife said, 'Yes, but if we do that, can we sell the house?'" Mobbs recalled, noting that in 1996, such off-grid living was virtually unprecedented in Australia.
The home attracted significant media attention, sometimes overwhelming his children. "My son had come home from primary school and said, 'Dad, everybody knows about the house. Now stop talking to the media'," Mobbs remembered. Despite initial embarrassment, he believes his children now take pride in the sustainable home where they were raised.
Ongoing Dispute with Sydney Water
Despite his successful off-grid transition, Mobbs faces an ongoing dispute with Sydney Water regarding stormwater drainage charges. He owes approximately $1,974.40 after thirty years of non-payment, despite receiving quarterly bills.
"By not paying Sydney Water, I am aiming to achieve this goal: to save cost of living bills for all Sydney households that have rain tanks and other solutions to stop or reduce stormwater leaving their properties," Mobbs explained. He has invited Sydney Water chair Niall Blair to visit his property to see the sustainable systems firsthand.
A Sydney Water spokesperson confirmed the outstanding charges apply to properties within designated stormwater drainage areas, regardless of connection to drinking water or wastewater services. The spokesperson noted ongoing engagement with Mobbs over several years but did not confirm whether Blair would accept the invitation to visit.
Inspiring Sustainable Change Beyond His Home
Mobbs now works primarily as a gardener and has expanded his environmental advocacy through initiatives like "coolseats" - benches with soil-filled troughs designed to reduce waste and benefit the environment. These have been installed in his local area and as far away as Melbourne.
His daughter appears to have inherited his environmental ethos, growing fruit trees and herbs at her own home with similar sustainability features. Mobbs encourages others to adopt manageable sustainable practices, suggesting even small changes can make significant differences.
"You don't have to do everything I've done," he advised. "Even if just including LED lights or installing a rain tank. You don't have to be a gardener, but you can grow things really simply, on your balcony or in the street, in a park or in a community garden."
The Chippendale terrace remains open to public tours, demonstrating that ordinary household functions - lights, toilets, refrigeration, and showers - can operate successfully without connection to municipal utilities. Mobbs' journey from lawyer to off-grid gardener continues to inspire sustainable living conversations across Australia.
