The 8 Most Exciting 3D Printed House Builds 2020

Traditional housebuilding methods may have changed in the last 200 years, but it has retained one key element — humans. Even with the latest diggers and cranes, people were still needed to pilot them. But now, industrial 3D printers can extrude concrete based on a 3D model and build houses completely autonomously. These gigantic 3D printers can build an entire 3D printed house in just hours!

3D printing offers the chance to build houses faster, more accurately and cheaper than ever before. We will be showcasing some interesting 3D printed house projects that already exist, the advantages and disadvantages of 3D printed houses, and mentioning some 3D printer companies who are working hard to commercialize the tech.

We have divided this complete guide to 3D printed houses into three parts:

  • Part 1: Five key advantages of 3D printed houses, and how 3D printed buildings would benefit us
  • Part 2: A selection of the most exciting 3D printed mansion, house and apartment projects

We have also published the complete history of 3D printing, which you can view here.

Part 1: Advantages of 3D printed houses

Environmentally Friendliness: 3D printing is a form of additive manufacturing and only uses up the exact material required to build a house. Therefore, in the building of a 3D printed house, less concrete and other materials are used up than traditional methods, benefiting the environment. Concrete production is one of the main pollutants, so minimizing this is key.

3D printed houses cost less: A large part of the costs in building a house is the labor involved, as houses take so long to construct. A house 3D printer only requires one person to monitor it, thereby vastly reducing costs involved in building a house – though there is the counterargument of putting people out of work.

Moreover, the University of Tartu, Estonia, with the Estonian University of Life Sciences, have collaborated to create a low-cost 3D printed house concrete material made primarily of peat which could reduce the material cost of building a house by up to 10x! Additionally, because peat is so common it could be dug up locally — such as in deprived third-world countries — and used to build houses, so materials do not have to be shipped there.

3D printed houses can be made quicker: Houses take between four and six months to build on average, but a 3D printer can print the structure of a house in just a day. With effective contractors to put doors, roofs and windows in, this means completed houses could be built in just a few weeks.

More options architecturally: Because 3D printing allows for accuracy far beyond what humans are capable of, complex designs can be created by 3D printers of all shapes and sizes. This is beneficial not just aesthetically, but also in the ability to create houses customized to be as efficient as possible as retaining heat, saving money, as well as creating environments that disabled people can live in comfortably.

Ability to help those in need: Being able to create basic shelter structures quickly, cheaply, with minimal labor and with accessible materials makes 3D printing the only clear option for the task. It is no wonder therefore that much research is being conducted in order to refine the technology, and with non-profits such as New Story attempting to utilize 3D printing in the third world.

However, it is still important to be realistic.

3D printed houses are likely not as cheap as the companies who have built 3D printed houses claim they are. They only list the cost of the house in terms of the materials consumed to build it, omitting key factors such as labor, the cost of the printer (renting or buying), interior and external finishing, and wiring, pipes and other key foundations.

The house in Nantes, France built for £170K is an accurate cost for a habitable 3D printed building, not the outlandish claims to build a fully-functioning domicile for $4,000.

Part 1: 8 Exciting 3D Printed House Builds

1. World’s Largest 3D Printed House by Apis Cor in Dubai

If you hear of an exciting or innovative building project, there is a high likelihood it will involve Dubai. Dubai have been championing ambitious architectural projects for years, and have recently made the bold move of aiming to have 25% of new buildings 3D printed by 2030.

This administrative building comprises two floors, featuring beautiful 3D printed architecture born out of an ongoing collaboration between Russian 3D printed house company Apis Cor and the Dubai Municipality.

We expect much more to come from Apis Cor in Dubai as this building is considered by them to be just a test for larger 3D printed house projects for the future. It is claimed to have been to test whether Apis Cor’s concrete 3D printer could print a building in Dubai’s heat — and passed with flying colors.

Expect more very soon: 3D printed apartment blocks, skyscrapers, landmarks and more.

2. First family move into a 3D printed house in France

  • 3D printed house price: £170,000
  • Located: France

In July 2018, a French family moved into their new four-bedroom home, becoming the first family to live in a 3D printed house. This was a collaboration between the city council, housing association, and the University of Nantes. The goal was to build a prototype with the long-term goal of creating 3D printed houses that are cheaper and faster to build than traditional houses. The house cost around £176,000 – 20% less than traditional construction.

This 1022 square foot 3D printed house took 54 hours to build — though this was just the structure. An additional four months for fitting the windows, doors, and other parts was necessary before the home was finished. The team behind this extraordinary achievement now believe they could create a similar house in 33 hours, citing additional knowledge and tech advances.

Benoit Furet, the man behind the project, believes 3D printed houses offer a solution to the growing housing shortage and for social housing in the future. Moreover, he claims that with growing economies of scale and technological advances, 3D printed houses will become 40% cheaper to build in 10-15 years.

Perhaps the most exciting part of this build however is the architecture – the house was built to curve around environmentally-protected trees. This is simply not plausible for traditional builds as they are more restricted by the shape of bricks, whereas 3D housebuilding can create curved shapes without issue. This offers potential for more compelling designs, as well as creating custom houses to suit disabled people.

3. Apis Cor 3D Printed House Built in 24 Hours

  • 3D printed house price: $10,000
  • Located: Russia

Probably the most famous and viral 3D printed house build, this interestingly shaped house was built back in 2017 in just one day – while it snowed! According to the team the house cost just over $10,000 to build, including the furnishings with windows and doors, though we will discuss why these figures may not tell the full story further on in this article.

A viral hit, this was definitely the moment the world woke up to the possibility of 3D printed concrete houses in the future. This viral video not only proved it could be done, but that 3D printed dwellings could be built faster than people could build them, and the cost of a 3D printed house was far lower.

Apis Cor’s build brought 3D printed structures into the public eye, encouraging others to get involved and democratize 3D printed house building.

4. ICON & New Story 3D Printed House in Austin, Texas USA

  • 3D printed house cost: $10,000
  • Located: USA

Another recent viral story, this collaboration between ICON and New Story made headlines when they 3D printed a house in Texas, USA earlier this year. The prototype 3D printed house built cost the companies approximately $10,000, though they assert that this number can be brought down to $4,000 going forwards.

The house, like Apis Cor’s 3D printed concrete house in Russia, was built in 24 hours, and is part of ICON’s longer-term plan to assist in infrastructure in poorer parts of the world through housing. Non-profit ICON has already built over 800 houses in Haiti, El Salvador, Bolivia and Mexico, and plans to utilize 3D printing to create low-cost houses in these areas – ICON currently source local workers but some areas may not have the skilled builders required.

Therefore, 3D printed houses offer a solution to this lack of skilled builder problem. Large construction 3D printers can be brought to these impoverished areas where there are few skilled builders to build homes for people in poverty. This is an example of 3D printing helping improve the lives of society’s most vulnerable, and we commend ICON and New Story for their fantastic work here.

This is also a project we are actually likely to see develop. New Story is Co-Founded and advised by some very powerful and successful people, including Glassdoor’s CEO, and Reddit Co-Founder Alexis Ohanian. Many of the people attached to the project have a track record of execution and success, so we look forward to seeing the project’s progress. Since the Texas project they have also printed a series of 3D printed houses in Mexico.

5. 3D Printed “Office of the Future” in Dubai

  • 3D printed building price: $140,000
  • Located: Dubai

Dubai is always making headlines for being ambitious and outlandish in its declarations of future goals – none more so than their claim that 25% of buildings will be built using 3D printing by 2030. And they’re backing this up with action; this office — claimed to be the most advanced 3D printed building in the world — cost roughly $140,000 to build (not including finishing details) and took 17 days.

Affectionately named the “office of the future”, the building was created by a 20-foot-tall concrete 3D printer using a robotic arm to deposit cement. Only one employee was needed to monitor the house 3D printer whilst it printed, and seven employees worked on building components of the office whilst the printer worked.

Additionally, 10 electricians and other specialists worked on the inner workings of the office across the 17-day build. We cannot therefore call it a completely 3D printed house, as other workers filled in various other components. But 3D printing has never claimed to be able to insert complex electrical systems as it prints, just create the structure in record time. With this project showing huge ambition, perhaps Dubai will become a world leader in 3D printed houses.

6. Gaia Italy 3D Printed Concrete House

  • 3D printed apartment price: $1,000
  • Located: Italy

Italian house 3D printing company WASP built ‘Gaia’, a 3D printed hut made from a mix of concrete and mud-based material. The 215 square foot structure took 10 days to complete, though the total time when accounting for all the furnishings and additions would be longer. The most extraordinary part is that the hut cost just $1,000 in materials to build, though this doesn’t factor in labor and other costs.

Like New Story’s plans for the developing world, this interesting prototype may form the basis for building houses in poorer countries. In more deprived areas where the imminent problem is shelter rather than wiring and pipes inside houses, these cheap 3D printed houses offer an effective solution to a real crisis.

7. Project Milestone, Eindhoven — Building 5 3D printed condos in Holland

  • 3D printed house price: N/A
  • Located: Holland

Project Milestone – the code name for the project to develop five habitable and beautifully shaped homes in Eindhoven, Holland, is a fascinating collaboration between Houben and Van Mierlo Architecten, Van Wijnen, and the Eindhoven University of Technology.

Pioneered as a solution to the shortage of skilled bricklayers in the Netherlands, the first of these houses – and the first 3D printed house for sale – attracted over 20 interested buyers in its first week on the market.

Though currently only the cement structure of the houses are 3D printed, with advances in technology it is hoped that by the time the fifth house is built that other features, such as drainage pipes, will also be made using the house 3D printer. This will further reduce costs and influence 3D printing’s adoption in housebuilding.

8. 3D Housing 05 – Milan Design Week

  • 3D printed house price: N/A
  • Located: Italy

A collaboration between engineering firm Arup and architecture studio CLS Architetti, and 3D printed by CyBe Construction; this stylish 3D printed house, named ‘3D Housing 05’, exhibited at Milan Design Week following its construction in November 2018.

The 3D printed home, built in a week on a Milan square using recycled concrete, is around 100 square meters and contains a living area, bedroom, kitchen, bathroom and roof terrace. Prominent 3D printed house constructor CyBe Construction created the house with their concrete 3D printer; able to print a single wall in between 60 to 90 minutes.

The most exciting part is the recycled concrete, developed by Italcementi, which uses debris from demolition sites to create the 3D printable material. This can then be recycled again after the building has been demolished.

Massimiliano Locatelli, the principal architect at CLS Architetti, claims that each square meter costs €1,000 to build – half the price of traditional construction. With advances in the technology, he believes this can be reduced to between 200-300 euros in the future.

How much does a 3D printed house cost?

This question of 3D printed house cost is a common one, and just as with traditional housebuilding, it depends. Though projects such as Apis Cor’s 24-hour build cost just around $10,000, this is a far smaller and more basic house than most in the West are accustomed to.

The same is the case for ICON and New Story’s 3D printed house in Texas. The house is small, basic and the house 3D printer had already been moved there. Therefore, for a 3D printed domicile a whole family could comfortably live in, it would probably not suffice.

The most accurate project in terms of a 3D printed house’s cost is the French build in number 2 on our ranking. This project cost around $170,000 and was roughly 20% than traditional methods would have cost.

However, construction 3D printing is still in its infancy, and will likely come down in price quickly. The main costs are the materials and labor, and without any labor required except one operator to monitor the print, these costs are dramatically lower.

When will 3D printed houses be available?

Arguably, they are already available. 3D printable houses are a reality, they are just not widespread. The companies developing construction 3D printers for houses are still refining the technology, and do not have enough of these machines to build thousands of houses yet.

We are likely to see a large increase in 3D printed buildings in the next decade or two, with countries like Dubai striving to 3D print 25% of new buildings by 2030.

Can I design my own 3D printed house models?

Yes, you can. There are a variety of architecture design software tools for creating 3D models of buildings. Architecture firms use 3D printing to create miniature versions of future building projects, and house 3D printers themselves create buildings based on 3D models.

Conclusion: The future of housebuilding

Though far from being perfected, the potential with 3D printed houses is exciting. It has proven to work and stand up to the elements in Europe and the USA, and really can work faster and more efficiently than people.

In poorer areas with few skills builders and little building material available, large house printers such as those by ICON and New Story offer a fantastic way to build basic huts and 3D printed shelters. If able to use locally source material, this reduces building costs dramatically, allowing for shelters to be built for those who need them most.

3D printing therefore doesn’t just promise to revolutionize construction for rich tycoons who want to boast about their latest build, but offers a scalable and effective solution to homelessness in the developing world.

The question now is how the technology will be received: will people resent concrete printers for making builders obsolete? Or will they take to them, glad that they can save them money on their dream build?

Even the most advanced house printers of the future will require skilled operators to prevent accidents, and we are a world away from a printer that can concurrently 3D print the glass windows, wooden doors, pipes, electronics and other furnishings along with the house.

House 3D printers therefore do not replace people, but complement them; doing the heavy lifting while the specialists do what they do best. It is important therefore to focus on how 3D printed houses can benefit both us and those in the third-world, and respect the advantages that 3D printed houses offer.
