Full construction of houses in factory, with reusable building materials, that are moved to the plot of land and can be moved to a different place afterwards.
Industrialization and modularization are key aspects that contribute to CE and buildings life-extension. This practice contributes to improve and enhance sustainable consumption and production patterns, through the promotion of the efficient use of natural resources and the reduction of construction waste generation. As a result of industrialized buildings, water consumption is really low, waste management is controlled, and the volume of waste is very small.
In this case, 82% of materials (dry construction) can be recovered and reused. But also, recyclable materials are used.
The company works directly with the supply chain, and all subcontractors and employees are locally based, so displacement and associated emissions are reduced.
Environmental impact is reduced given that the time of installation on site is very reduced, so there are no long periods to bother neighbourhood.
The company has agreements with various public administrations (chamber of commerce, municipalities) for employee training in its industrialized systems. Programs are especially aimed at the most disadvantaged groups: young people, women and those over 50 years of age.
Banks facilitate access to financing for the self-promotion of the house because they perceive less risk as the delivery date and budget are closed in advance, and there are no unforeseen expenses.

Resources needed

82 people to build a house 300m2 in 8 weeks

Evidence of success

The company started its activity 8 years ago. At that time, they did not build houses in a factory, so they realized it was impossible to control the building in the way they are usually built. Therefore, they decided to start the factory 3 years ago. In the beginning, the staff was composed of 5 architects and now 82 people are working directly in the factory, and 60 people are subcontracted.

Difficulties encountered

The company began during the construction crisis by building low/mid-range homes since the initial idea was that the turnkey, price and closed-term system would favour this type of client. The market has pushed the company to high-quality living and comfort standards.

Potential for learning or transfer

Traditionally, the construction sector in Spain and Valencia region has been a low-industrialised and highly labour-intensive sector, which means: lower quality, less precision, higher risk of unforeseen events and economic deviations, generation of surpluses, greater environmental impact.
Industrialised construction improves all the above aspects. It is important to highlight how this commitment to industrialisation represents the main value of a company. InHAUS practice improves the quality of the final product and therefore customer satisfaction, working conditions of employees, and has a positive impact on the environment by less consumption of resources and energy.
The system is being transferred now to the tourism sector (hotels) which have seen an added value in the possibility to move the buildings to another location, in case the initial location is not profitable enough, other destinations become popular, or in anticipation of the possible impact of climate change.
