BUILDING TWO AT A TIME
If you’re planning a knockdown rebuild project and thinking about including a granny flat in the backyard, there are benefits to getting both homes built at the same time by the same builder.
“There’s a big cost saving because we can build at the rates that we’re building the house at,” new home builder Allworth Homes director Stephen Thompson says.
A granny flat built with bricks, tiled roof, timber frames on a slab can cost about $80,000 when built at the same time as a main house.
“If I tried to get trades out to build a granny flat on its own it would cost at least 10 per cent more, maybe 15 per cent more,” Stephen says. “Because to get a bricklayer out to do 1500 bricks, he won’t do it at the rate that he would do the whole house at.”
Stephen says most of Allworth’s Sydney granny flats are built as part of knock down rebuild projects, but people trying to maximise rent returns would be in the minority.
“The bulk are just trying to house family on the block as comfortably as they can, particularly in the Ryde, Auburn and Bankstown areas,” he says.
“They build a decent twostorey home in the front and put a two-bedroom granny flat in the back.”
Stephen says while it’s hard to find the right-sized block to fit a house and granny flat in a greenfields area, sites can be found in areas such as Oran Park in south western Sydney.
Allworth Homes have 10 granny flat designs in their Smart Space series.
