Every Elpor granny flat is priced to be ready to live in. The price includes:
All our granny flats are built to a 7-star energy rating, with a low-maintenance Colorbond exterior.
Prices are subject to site conditions. We inspect your site before you sign anything, so you’ll know about any extra cost up front. The things that can change the price are:
Narrow access is rarely a problem. Our panels are carried in individually, so we can build on sites with narrow side access where a conventional builder can’t get materials through. If your property is in a bushfire area, we can check it at the initial enquiry stage.
A granny flat is a complete, self-contained home with its own kitchen, bathroom and laundry provisions. A sleepout is a habitable outbuilding: a room, or a room with an ensuite, but no kitchen. It suits a home office, a teenager’s retreat or a guest room, and costs considerably less, from $56,550. Both need a building permit, and we include it in both.
Typically three to four months all up, depending on permits and our schedule. Once construction starts, it’s about six to eight weeks to handover. The unit is prefabricated in our Carrum Downs factory and assembled at your place, which keeps disruption in your backyard to a minimum.
