Homes built with 3d printer

3D Printed Houses: Top Projects from Around the World

3D printing news News 3D Printed Houses: A Closer Look at Completed Projects from Around the World

Published on July 29, 2022 by Carlota V.

As you may know, additive manufacturing is becoming increasingly important in the construction market. The new technologies make it possible to create more complex shapes, build walls faster, and reduce labor costs. Many construction companies have already started to 3D print buildings or houses. Be careful, however, with the term 3D printed house: In most cases, only the walls are made by a 3D concrete printer, that prints them layer by layer. That in itself is already quite an innovation that has made it possible to build homes in hard-to-reach, disadvantaged, or conflicted areas. These days, we are starting to see more and more 3D-printed houses being inaugurated and the first families are starting to move in. Yet, at this point, it is still difficult to assess the sustainability of such a structure, and only time will show if this manufacturing method is more viable altogether. However, we can already share with you some 3D printed house-projects that have been completed around the world.

A 3D Printed House in Japan

In less than 24 hours and for less than $25,500, the company Serendix designed this small house with 3D printed walls. Even if it’s hard to imagine that anyone could live in it, the project is still interesting and shows all the agility of 3D concrete printing. With a surface area of only 10 square meters, the structure has a honeycomb shape and no reinforcements. Serendix’s objective is to create emergency housing in times of crisis, as earthquakes and typhoons regularly hit the country. It took three hours to assemble the different 3D printed parts and a total of 23 hours and 12 minutes to get the final result.

Alquist 3D and the Virginia Project

U.S.-based Alquist 3D recently announced the launch of one of its new projects for 3D printing homes. Located in the state of Virginia, the 200 homes that make up the project will be created through additive manufacturing with the aim of reducing the overall cost of infrastructure in communities with economic problems. According to the company, which specializes in 3D printing houses with concrete, this initiative is intended to be one of the largest housing construction projects, with Pulaski and Roanoke being the first cities to be chosen for it,  due to the growth in demand for housing that these areas have experienced in recent years. After completing the project for Habitat for Humanity, this new idea now aims to help the company expand further into the 3D construction market.

The Fibonacci House, the First 3D Printed House on Airbnb

The next house on our list is interesting not just for its design but because it holds the distinction of being the first fully 3D printed house to be listed on Airbnb. Twente Additive Manufacturing (TAM), one of the leading companies in concrete 3D printing, created this home in a spiral shape following the Fibonacci sequence, a famous mathematic sequence also known as the golden ratio that often occurs naturally, giving the home its name. The spiral allows for the progression of space from the wide-open exterior to the closed and warmer space in the tightest part of the spiral. The tiny home is available for rent for a minimum of two nights in Proctor, British Columbia, Canada on Airbnb for about $128 a night..

Mvule Gardens is Africa’s Largest 3D Printed Housing Project

Continuing the trend of 3D printed houses being used for affordable housing, Mvule Gardens is a neighborhood consisting of 52 houses, it is Africa’s largest 3D printed affordable housing project. Built by 14Trees, a joint venture between Holcim, a global leader in sustainable construction solutions, and CDC Group, the UK Government’s impact investor, the project hopes to address the housing shortage in Kenya. The homes were built using the BOD2 printer from COBOD and a 3D printable dry mortar called TectorPrint from Holcim, ensuring that the houses are adequately strong and can be made with a reduced carbon footprint. Both two-bedroom and three-bedroom homes are available and 14Trees notes that they hope they will help to make green, low-income and affordable housing a reality for Africa.

Azure 3D Printed Homes for Sustainable Construction

With the goal to develop homes faster, more economically, and with less environmental impact, Ross Maguire and Gene Eidelman brought Azure 3D Printed Homes to life in 2019. By combining years of experience in building and developing properties all over the world, the company has already been able to 3D print several environmentally friendly houses. The company uses recycled waste materials to create the structure of the houses, which are then produced with a large-scale 3D printer in only 24 hours. Azure 3D Printed Homes offers a variety of backyard offices and homes, one example is its Azure Marina Model. This 360 SQ/FT studio consists of a bedroom, kitchen, and bathroom, and can be customized and ordered on the company’s website.

Habitat for Humanity Uses AM For Homes in Low-Income Areas

Atlanta-based nonprofit organization Habitat for Humanity has been able to support millions of people all over the world by helping to construct and preserve houses and shelters. Last year, in 2021, the organization finalized its first house using 3D printing technologies. The 1,200-square-feet house that is located in Williamsburg, Virginia, was the first 3D printed house to be owner-occupied in the United States. To create the house, Habitat for Humanity partnered with 3D printing home construction company Alquist 3D, which used a large-scale 3D concrete printer to produce the house in only 28 hours. The home features a kitchen, three bedrooms, and two full bathrooms. The nonprofit also has been working on building 3D printed houses in other states including Arizona.

House 1.0, Europe’s First 3D Printed Tiny House

The House 1.0 is the first 3D-printed Tiny House in Europe. It was made by Danish 3D printing startup 3DCP Group using concrete 3D printers. The company’s goal with this house is to build better, faster, greener, and reduce the amount of effort required in the construction process. The Tiny House is designed to be as cost-effective as possible and to provide owners with all the necessary amenities despite its small size of only 37 m2.

SQ4D Puts the First 3D Printed House on the Market

SQ4D is a company that has completed the construction of the world’s largest known 3D printed house. The house, which was printed and built entirely on-site, is approximately 180 m2 in size and required only forty-eight hours of printing time, which was spread over a period of eight days. The materials used in the manufacturing process had a total value of less than $6000. The company continues to strive for innovation and plans to cut the printing time in half for subsequent projects in the future.

Prvok, the 3D Printed Houses in the Czech Republic

Whether in the countryside, in the city, or even on water, the 3D-printed house called Prvok was born in the Czech Republic and was created through the collaboration of Buřinka, a visionary company from the construction sector, and sculptor Michael Trpák. Built of concrete, the house can be printed in just 22 hours due to the printing speed of 15 cm per second – and with a size of 13.35 m x 3.5 m x 3.1 m. The robot arm thus produces a living area of 43 m2. With a total of three rooms – a bathroom with toilet, a living room with kitchen area, and a bedroom – the building can even be solidified on a floating hollow body, making it habitable on the water all year round.

Viliaprint, the Project Combining AM and Conventional Construction

This project combines additive manufacturing and conventional techniques for building houses. The project called Viliaprint was inaugurated in June of this year in the French city of Reims, more precisely in the eco-district there called Réma’Vert. A total of five houses, with each having living spaces ranging from 77 to 108 m2, were built thanks to the collaboration of stakeholders. The promising project aims at improvements in social, economic, and sustainable aspects. In the 3D printing process, which did not take place directly on site, the designers behind the 3D printed homes placed particular emphasis on concrete that dries as quickly as possible after each layer is applied so that it can hold its own weight.

COBOD and PERI Partner for Incredible Houses Build Using AM

PERI is a company founded in 1969. In 2018, the group acquired a minority stake in COBOD, a leader in 3D design, and since then the two companies have been working together. In 2020, they built the first 3D-printed house in Germany and the largest apartment building in Europe. The house, printed in the Rhineland region of North Westphalia, is a 160-square-meter, two-story single-family home with three-layer insulated cavity walls. The COBOD BOD2 printer was used for the construction, which is characterized by its ability to extrude concrete at a speed of up to 100 cm per second, resulting in the desired project size, smooth and straight walls, and the highest quality requirements. With the CODOB printer, it is possible to build up to 300 square meters on 3 floors at an unprecedented speed. PERI firmly believes that 3D printing will one day, revolutionize the construction industry.

Project Milestone, the 5 3D Printed Homes in the Netherlands

This next housing project is located in the city of Eindhoven in the Netherlands. It consists of five 3D-printed concrete houses. Although the houses have already been sold,  you can rent them from a real estate company. Each of them is made of 24 individual concrete pieces that took 120 hours to print layer by layer. These 24 pieces were then moved to the location where the house is currently located and assembled, attached to the foundations, and fitted with a roof, windows, and doors. The buildings have a futuristic design, which makes the houses look like they are abandoned, reminiscent of rocks in an oasis surrounded by trees. The houses meet the ultimate comfort needs and were built in a sustainable and energy-efficient way. The surrounding area is bright, yet quiet, and provides a great place to relax.

Habitat for Humanity's First 3D-Printed Home Is the Future of Construction

habitatpgw. org

Founded in 1976, Habitat for Humanity has constructed hundreds of thousands of affordable homes for people who need them. Now, using automated computer technology and a patented concrete mix, Habitat for Humanity recently completed its first 3D-printed house in Williamsburg, Virginia. The house’s new owner, April Stringfield, and her 13-year-old son are excited to move in and make the house a home.

While 3D-printed homes are still relatively rare, the successful completion of the Williamsburg house is a testament to the growing desire to build affordable homes while conserving natural resources like trees.

Although the walls of the Williamsburg house were printed rather than stick-framed, the home is still just a regular house. In 1,200 square feet of living space, it includes three bedrooms, two full bathrooms, and a covered front porch where Stringfield can enjoy warm summer evenings.

The contractor incorporated traditional siding on the roof gables and used standard bricks on the porch pillars. In addition to the house, Stringfield received a 3D printer that will allow her to print cabinet hardware and light switch covers.

During the pandemic, some building material prices doubled or tripled primarily due to supply chain issues, which subsequently drove up homebuilding costs. By using concrete rather than wood, Alquist—the contractor that printed the walls of Stringfield’s new home—saved Habitat an estimated 15 percent per square foot.

While homebuyers do not pay for the labor needed to construct a Habitat home, they do pay for the cost of construction materials. In this way, the money saved on material costs is passed on directly to the buyer.

It took just 28 hours to print the concrete walls of Stringfield’s home. Alquist uses a patented concrete mix and impressive-looking extrusion machine to print exterior and interior walls, which are reinforced with steel during the printing process.

Afterward, the exterior walls are sealed with a clear or tinted coating that keeps moisture from transferring through the concrete. Homeowners can choose a standard gray concrete color or select from a range of attractive earth tone hues to give the home a custom look.

After Alquist finished printing the walls, traditional builders constructed the roof, ran plumbing and wiring, and installed interior flooring and other finishes. Through the Williamsburg chapter of Habitat, contractors, subcontractors, and other volunteers donated their time to complete the remaining parts of the house.

As a Habitat rule, new homeowners must spend some of their own time working on the project, so Stringfield put in 300 hours of sweat equity to make her new home a reality.

While the Williamsburg house is the first 3D-printed home Habitat has completed, it likely won’t be the last. The Habitat buyer program exists to help encourage homeownership for those who need housing but might not be able to purchase a home through conventional means.

Successful Habitat home applicants commit to working on the project or at a Habitat ReStore, and they learn how to budget for mortgage payments and care for their new home. The nationwide nonprofit does not discriminate when selecting homebuyers.

Automated 3D printing for homes is still in its infancy. However, computer-constructed homes are already being built and sold to the general public, such as this 3D-printed house located in Riverhead, New York. In most communities, however, standard construction is still the name of the game and will likely remain so for the foreseeable future.

Stringfield is thrilled with her new home, and she told CNN how thankful she is to have a home with a backyard where her son can play and her puppy can run.

Europe's first fully 3D printed home welcomes its new occupants, a couple from Amsterdam

What's happening

What it means

The creation of the first fully 3D printed house in the Netherlands is just the beginning of a new phase in the industry. Residential buildings built using 3D printing technology have a number of significant advantages over "classic" buildings. Firstly, the speed of the project, the first house was printed in five days, but going forward, the company plans to produce concrete elements on site, as well as use a 3D printer to create auxiliary installations, which will reduce construction time and costs.

In addition, in an era of global concern about the state of the environment, such "green" technologies help to reduce environmental damage to the environment - with 3D printing, the consumption of cement and waste of building materials is much less than with "traditional" construction.

Finally, with the help of a 3D printer, almost any design idea can be realized, which will allow you to move away from the concept of residential buildings in the form of "concrete boxes". The development of this technology makes it possible to erect buildings of such forms that are difficult and expensive to build using traditional methods.

The technology of printing houses on a 3D printer is actively developing in Russia, France, the USA and other countries. It is assumed that this will help solve the problem of providing citizens with affordable and decent housing.
