Less is more for these tiny house-loving sisters in the Blue Mountains

For almost five months, two Faulconbridge sisters, Tamar and Kiara Devine and their builder Dad, Colin, have been busily working away in their driveway creating a tiny house from scratch on top of a trailer.

And now they would like their driveway back.

The tiny character house of about 15 square metres that they have built, is ready to be delivered to its new owner for $70,000.

Potential buyers can step inside to the smell of Tung oil and find purpose-built cabinets, stunning copper sheets on the shower wall, as well as pressed metal, a copper kitchen and bathroom sink and a loft upstairs for sleeping in. They salvaged the doors and stained glass windows from a heritage home. The wooden floors were milled and sourced in Trundle and the arched roof gives extra space in the mini bedroom. It's ready to go.

"There isn't a toilet yet so the buyer can decide if they wanted a composting or flushing toilet," Kiara, 22

"It needs to be connected to gas bottles to heat the water, and you plug it in like a caravan for electricity. They [these homes] are cheap to heat, because they are tiny."

Built with the efforts of their family and close friends, the sisters stopped their jobs as house painters for several months to work on the project with their dad. All three spent more than 300 hours each on the project. Contractors did the plumbing and electricals.

Because of the loft bedroom, they expect a young couple might buy the house instead of an older one. "It's so romantic with the lighting."

"(My brother) Coen (12) helped with the cladding, sister Bianca (14) did the putty and helped with the nails. Dad was the brains and the bank. Mum kept us fed," Kiara said.

"We've enjoyed it, but it will be good to see it go."

The family is moving to the Central West soon and hope to continue their Tiny House in the Mountains business from there.

"The main reason we like tiny living is because it simplifies life and enables people to live more within their means," Tamar, 25, said.

"Tiny living is sustainable in many ways, not just ecologically, but economically and socially as there is less pressure to need to work long hours and more time for people to be able to spend with family and friends which is very important," Kiara added.

She thinks that's also the reason it is becoming "a popular movement".

"People were created for community, for relationships and some people are realising it again."

"That's what I like about them," Tamar added. "It forces you to live simply. As a society we overconsume."

The girls said they didn't know about any TV shows about tiny homes before they started the project, but did watch a few YouTube videos.
