During the last seven years Sasha Veselinovic has developed an innovative construction system to prefabricate house components in North Wollongong.
Mr Veselinovic has fine tuned it to the point where panels and walls can be erected onsite to lockup stage on a two storey house in seven days and a duplex in 10.
The Panelup Offsite Manufacturing Company factory he developed is located near his other business, Unique Style Homes, in Montague Street.
And the product is so popular he has been putting on more people during COVID-19 to meet the growing demand in the Illawarra and Sydney. In fact work starts on a new two storey architecturally designed duplex in Matraville on Monday.
"It is a big job. We are aiming to have the roof on and have it to lockup stage in probably nine to 10 days. The whole progress can be followed on Instagram and Facebook".
Mr Veselinovic began exploring the use of prefabricated SIP panels with Bondor Australia in 2013. Structural Insulated Panels were first invented for the construction industry in the 1930s and are known for their strength, bracing and insulation properties,
By 2014 Mr Veselinovic had designed a 'prefab wall' and a 'machine press' to manufactures prefab house walls. It wasn't long before he started testing his own prefab system designed to speed up construction by more than 50 per cent.
"The first ones I made were for a granny flat. Then I made them for a house and a duplex. A few years later we had a system where we could do a whole house within seven to eight days".
After five years of testing this system was presented at Darling Harbour Home Show in 2018 and at the Canberra Home Show in 2019.
"We actually did a two storey house in Mangerton last week that took us only seven days from the slab up to the roof".
It was a prefab custom double storey 330m2 house with five bedrooms and four split levels.
Mr Veselinovic's other company Unique Style Homes is the one that completes houses from start to finish using the system.
Panelup manufacturers a range of products from external and internal walls to prefabricated floor cassettes, bathroom pods, timber frames and insulated roofing panels that all fit together perfectly within days of arriving onsite.
Mr Veselinovic is getting so much work he is not actively encouraging other builders to use his system. "But I do have a lot of interest".
He presently employs 10 people including subcontractors at Panelup and Unique Style Homes. "We are definitely growing. We have employed five more people in the last four months including two skilled carpenters, a site supervisor, 3D detailer and an apprentice. And I am still looking for more staff".
Mr Veselinovic has not stop innovating and is presently planning some automation that will allow him to manufacture a two storey house in less than a week.
The whole process at the North Wollongong factory starts with using 3D BIM software to model each project.
Every component is detailed to the millimetre before being imported to scheduling software.
Employees are assigned with each task and detailed instructions from material ordering to manufacturing and site installations. They each have a quality control check list accessible via computer and the business is presently 99 per cent paper free. All off-cuts in the factory are fully recycled.
