September will be a month of great innovation for the property market, as a 3D printer will produce the first prototype flat.

It's becoming increasingly difficult, even impossible, for young people to buy a house in Portugal, and this calls for a collective effort on the part of companies to initiate sustainable, fast-track housing projects at affordable prices. In this context, and according to Ecosteel, 20 million will be invested in the modelling construction industry so that around 3,000 3D houses can be put on the market each year. These will be more affordable homes, making it possible to access them.

José Maria Ferreira, from Ecosteel, points to an estimate of 300 houses made by 2024. These will be modular homes, built in an old shipyard, and the first prototype is due to be completed this month.

According to the entrepreneurs, a one-bedroom house will sell for around 100,000 euros, adding that this price is possible thanks to the acceleration of processes, the reduction of labour costs and the innovation of industrial house building.

What are the characteristics of 3D houses?

It's worth noting that these houses are made with a mixture of plastic and a concrete cover, in order to guarantee the safety and stability of the construction. 

Once the walls are in place, which is done on the site where the house will be located, the finishing touches are applied, such as windows, doors and roofs with solar panels, to create an energy-efficient living space.

It is known that the future owners of these houses can choose between several floor plans already designed, which correspond to a range of houses between 150 and 200 square metres, with three to four bedrooms and two to three bathrooms. To promote more sustainable energy consumption, these houses are equipped with the latest solar panel technology.

Advantages of 3D houses

  • Less chance of errors: since much of the work is done by machines, there is less room for error;
  • Reduced costs: it is known that the first 3D house built cost 20 per cent less than a traditional home. It is also estimated that this figure will drop to 25 per cent in 5 years, and 40 per cent in 10 to 15 years;
  • Speed of construction: these houses tend to be built more quickly;
  • Sustainable construction: 3D printers can use different materials that are more sustainable, such as sand, fibres and recycled materials.

Disadvantages of 3D houses

  • Only prints walls: at the moment, 3D printers are only capable of printing walls, meaning that the rest of the house will have to be made manually or to order;
  • High initial investment: buying a 3D printer is still expensive, so companies still find it very difficult to enter this market;
  • Labour: there are still few people qualified to operate, transport and assemble these machines;
  • Technology: at the moment, this technology has not yet been widely exploited.

What are the practical applications of 3D houses?

These houses have already begun to be put up in various parts of the world, such as Morocco, where the Spanish company Be More 3D built a property in order to reduce CO2 emissions and guarantee affordable housing for the inhabitants of Ben Guerir by constructing a 32 square metre house in 12 hours.

In Russia, a rounder-looking house was built, and the company responsible for the project, Apis Cor, one of the most innovative companies when it comes to 3D houses, says that the house is just over 38 square metres, built in one day and designed to withstand the area's inherent cold.

The village of Massa Lombarda, 40 kilometres from Bologna in Italy, has received a house built using efficient and durable materials as part of an eco-responsible initiative. The project was led by 3D printer manufacturer WASP. The materials used in the construction of this house were mud and waste from rice cultivation, and the house took 10 days to build, which is still a much better timeframe than if it had been built using the traditional construction method.
