Norris saved up a 20 per cent deposit for the relocatable home - through previous jobs and living at home - and received a loan from a family member for the remainder.
“This felt like a great use of that money to take a step forward towards home ownership,” she said.
The home is connected to the main property's electricity and plumbing, with Norris splitting these bills with her mum.
While she said the home wasn't huge, Norris said it was the "perfect size" for herself and her dog.
VanHomes founder Vito Russo said “instant homes” were gaining popularity among Aussies looking for a cost-effective way to get into the property market.
"We are seeing an increase in the number of people turning to instant housing because of all the benefits it offers,” he said.
“Not only is it cost-effective, it actually travels with people as their lifestyle and family situation changes. This is one of the key reasons why people are finding that it is the ideal solution.”
Building Ministers have agreed to work together to "cut red tape" surrounding the prefabricated and modular construction industry.
“We need to build more quality homes quickly - prefab and modular housing gives us a chance to do that,” Minister for Industry and Science Ed Husic said.
“We need to pull every lever to help use advanced manufacturing to support the rollout of these homes.”
VanHomes relocatable homes range in price from $65,000 up to $136,000 for a three-bedroom home and arrive on site with all fittings and fixtures included.
Resales have typically been about 90 per cent of the home’s original value if well maintained.
Norris said she hopes she will be able to buy a standalone property in the next 10 or 20 years but said this goal still “seems so unachievable”.
Australian home values rose 0.5 per cent in August, the 19th consecutive monthly increase reported by CoreLogic. The median home is now worth $802,357, while in Sydney it is $1,180,463.
Norris said she is glad she bought her relocatable home and said having it in her mum's backyard meant she could still be close to her family while enjoying her own space.
“I still have that reliable source to go back to Mum if I need something or with any issues she is close by to help. And if she needs my help, I’m close to help with my sisters or whatever it is,” she said.
