Cullacabardee fire downgraded after threatening homes in Perth Aboriginal community

  Cullacabardee fire downgraded after threatening homes in Perth Aboriginal community Authorities downgrade a warning for a bushfire that came close to homes in the small Aboriginal community of Cullacabardee in Perth's north-east.An emergency warning was declared this evening after a fire began in scrubland near the community, about 22 kilometres north-east of Perth's CBD.

In a rainy, rural site in the Mexican state of Tabasco, a pair of 3D-printed homes represent a milestone: They're the initial two structures in a community that aims to be the world's first 3D-printed housing development.

This month, a team of designers and philanthropists unveiled the houses, which are part of a planned 50-home neighbourhood for low-income families.

It's the result of a collaboration between New Story, a San Francisco-based housing nonprofit, and Icon, a construction-technology company that designs 3D printers.

  Bushfire north of Perth a risk to homes Authorities have issued an emergency warning for a bushfire in the City of Wanneroo, about 25km kilometres north of Perth, that's threatening lives and homes.Residents in parts of Yanchep in the city of Wanneroo north of Perth are being urged to leave immediately as firefighters battling a large bushfire.

Unveiling the World ’ s First 3 D Printed Community . It’s been more than a year since New Story revealed its ambitious The 3 D printed homes also come with electrical and water hookups. There’s also a zero profit mortgage that costs about $ 20 per month , which will run for seven years.

Take a look inside the brand-new structures.

At 500 square feet each, the homes take just 24 hours to print.

Icon's printer, known as Vulcan II (shown above), weighs about 3,800 pounds. It can operate during a power shortage and comes with LED lighting for printing at night.

The Vulcan II is operated via controls through a tablet, so only a few workers are required to print a home.

The printing process is relatively simple: The printer churns out layers of cement, which amass to form the walls of the home.

The company's cement mixture is stronger than traditional building materials, so it can withstand extreme weather conditions.

Non-printed fixtures like doors and windows are installed at the end of the process.

To select who will get to live in the community, New Story surveyed more than 500 local families. The group promised the homes to 50 families with the greatest financial and physical needs.

The up-front cost of building the homes and necessary infrastructure was funded by New Story donors. The nonprofit declined to say how much the houses cost, but it previously estimated that it could build a 600- to 800-square-foot home for $US4,000 or less.

These fast and affordable 3 D houses will be printed locally in El Salvador to help those in need of housing. It was unveiled during the SXSW Conference 2018 earlier this month . The main material used is Portland cement. Cite: Keshia Badalge. "In World ' s First 3 - D Printed Home Community

As profiled here, in 2015 the world ' s first 3 D - printed apartment building was constructed in China, with the structures printed off -site. “Printing of self-bearing walls, partitions and building envelope were done in less than a day: pure machine time of printing amounted to 24 hours ,” the company said.

A local nonprofit, Échale, helped select the winning families, most of which are among Tabasco's indigenous population.

The nonprofit also solicited feedback from future residents about the community's design. The vast majority of families wanted flat roofs so that it would be easier to add to or customise their home.

Residents will be required to pay a small mortgage of 400 pesos (about $US20) (29.09 AUD) per month for seven years.

The mortgages come with zero interest and the money goes into a community investment fund meant to be spent by the residents.

Many Tabasco residents struggle with poverty and violence in their communities. The median family income there is $US77 per month.

Tabasco has the highest unemployment rate of any state in Mexico.

In 2017, police registered nearly 390 murders there - triple the number in 2012. In 2018, a Mexican journalist was shot and killed in Tabasco.

This tiny home was 3 D - printed in 24 hours . To determine who would live in these homes , the team partnered with the local government to survey more than 500 families. The pair of gabled homes were built on a single lot by architecture students at the University of Kansas.

The new homes come with two bedrooms, a living room, a kitchen, and a bathroom.

"I can't wait to have bedrooms where my family can sleep more comfortably and more protected from the cold and the mosquitoes," Isela, one of the community's future residents and a mother of two (who did not provide her last name), said in a statement. "If it rains, I know it's not going to make our floors muddy; that is how my home is now."

The new community will also offer parks and green space.

Almost all of the families surveyed asked for green space near their homes. A quarter of those surveyed said they considered green space the most important feature of their future community.

But the community's rural location and some rainy weather posed a challenge for the builders.

Though the actually printing process took 24 hours, planning for the development lasted 18 months.

"The journey has not been easy," New Story said in a statement on its website. "Power can be unpredictable and local rainfall has often flooded access roads to the construction site."

The two printed homes will soon be joined by 48 more structures, but the rest likely won't be 3D-printed, despite the group's intent to build the first 3D-printed community.

Instead, New Story plans to use a material called Eco-Block: a type of brick made from organic waste that's stronger than traditional concrete and produces fewer carbon emissions. The nonprofit will then compare whether Eco-Block or 3D printing holds up better over time.

For now, the 50 families are still living in their old homes. An official move-in date hasn't been decided yet.

The two 3D-printed homes won't be occupied until the entire community is completed.

"The thing I am most excited about for my new house is having my own room where I can read," 8-year old Alan (who did not provide his last name) said in a statement. "Where I live now, we can't read much, because when our parents bought us books, they would always get wet because of rain coming in through the roof."
