Elpor Pty Ltd has been building granny flats, sleepouts and bungalows in Victoria since 1985. Four decades on we are still family owned and family run, still manufacturing in our own Carrum Downs factory, and still installing with our own crews rather than subcontracting the work out.
In that time we have built thousands of units across Melbourne and regional Victoria — for families making room for a parent or an adult child, for homeowners adding a home office or a studio, and for property owners adding a second dwelling to an existing block.
We are a registered building practitioner, CDB-U 53184, and every unit we supply carries home owners warranty and a six year and six month structural guarantee.
Because we manufacture what we install, one company is responsible from the first site visit to the day you get the keys. You deal with the people who make the panels, quote the job, lodge the permits and put the building up. Nothing is handed to a third party and nothing gets lost between trades.
Our interlocking sandwich panel system is what makes that possible. Panels are made to order in the factory, delivered flat and assembled on site, which keeps build times short, keeps site disruption down, and lets us reach places a conventional builder cannot — through a garage, down a side path, or through a standard gateway.
The best way to understand the quality of an Elpor build is to walk through one. Our display units are at 57 Access Way, Carrum Downs, open during business hours Monday to Friday and Saturday mornings strictly by appointment. Come and see the panel system, the finishes and the internal layouts in person, and talk through what will fit on your block.
Call 03 9782 9894 or send us your site details and we will tell you what is possible.
Our building system is unique with our interlocking sandwich panels, which have an insulation rating higher than a normal dwelling. This gives Elpor Pty Ltd the ability to easily achieve a 7 star energy rating
Elpor Granny Flats and Sleepouts are also very low maintenance – using mostly external ColorBond.
The buildings have no load bearing internal walls, – you may have any internal design that suits your requirements.
Elpor Pty Ltd is making the most of modern technology using high R rating polystyrene and our unique interlocking ColorBond panel system.
Elpor is the leader in providing quality granny flat solutions. Using high-tech material and interlocking properties have many benefits for our clients such as extremely high insulation rating and also acts as a high sound deadening agent. They are also very low maintenance because of the ColorBond panels.
Our Granny Flats and Sleepouts are prefabricated to order in our Carrum Downs factory and put together on site. Due to our unique panel system we can access any site; through garages or carports providing we have a gateway to walk through.
Granny Flats can be easily modified for wheelchair access - including a step less shower with a folding shower seat, a lowered front door jamb, a 1: 14 gradient access ramp and stainless steel grab rails fitted to the bathroom & shower.
Elpor Granny Flats provide quality and comfort at an affordable price. Our unique panel system reduces build costs, while excellent insulation and low-maintenance materials keep ongoing expenses down. With long-lasting durability and the ability to relocate, you get genuine value for money.
As our units come in flat packs, once the Granny Flat has been completed it is easy to relocate by a tradesman or handyperson. This means you can take it with you if moving house, or simply sell it and recover a good portion of your initial outlay, proving another advantage to our clients.
