Industrialization: a strategic lever to transform construction

• Opinion piece, published in El Economista on April 7, 2026

The construction sector is at a critical juncture. Long-standing challenges-low productivity, extended delivery timelines, a shortage of skilled labour, and growing cost pressures-are now compounded by an urgent societal need: to deliver housing faster, more efficiently, and more sustainably. In this context, industrialization has moved beyond being an emerging alternative to become a central driver of transformation.

Industrializing construction involves shifting a substantial part of the building process to controlled, safe manufacturing environments. In these settings, standardization, technology, and meticulous planning combine to enhance efficiency, quality, and reliability. While this model is already well established in several European countries, it remains at an early stage in Spain. Currently, only around 2-3% of homes are built using industrialized methods, compared with 7-10% in countries such as Germany and the Netherlands, and even higher shares in the Nordic countries, according to the Building Cluster.

That said, the model's potential is unmistakable. Industrialized construction can reduce delivery times by up to 40%, largely thanks to parallel workflows and the off-site manufacturing of components. Residential developments that would traditionally take 18 to 24 months can be completed in under a year, with a direct impact on financing costs and the sector's ability to respond to housing demand.

However, speed is only part of the equation. Factory-based production significantly improves build quality, reduces variability and waste through the adoption of lean management practices, and enables full traceability throughout the process-particularly when integrated with digital tools such as BIM. Moreover, concentrating activity in controlled environments optimizes material use, supports circularity, reduces waste and CO₂ emissions, and facilitates the adoption of lower-impact construction solutions.

Employment is another area where industrialization is having a meaningful impact. Traditional construction is facing a growing shortage of new entrants and specialized professionals. Industrialization helps address this challenge by creating new technical roles more closely aligned with manufacturing, automation, and advanced process management. It also brings substantial improvements in working conditions: safer environments, indoor workplaces, better ergonomics, and greater job stability. Unsurprisingly, this model is also helping attract more young people and women into a historically male-dominated sector.

From an economic standpoint, industrialization brings greater certainty. Standardization and forward planning reduce unforeseen issues, improve cost control, and enhance overall project profitability. Indeed, industry analyses suggest that the internal rate of return for industrialized developments can be four to five times higher than for traditional methods, largely due to shorter timelines and lower risk.

Recognizing this potential, Spain has taken important steps in recent months. The announcement of a €1.3 billion PERTE programme for industrialized housing, together with the forthcoming Housing Law 2026-2030, sends a clear signal of institutional support to modernize the sector, drive innovation, and scale up production capacity. These initiatives, alongside other financial instruments currently under discussion, could prove decisive in overcoming persistent barriers such as high upfront investment, the need for more suitable regulatory frameworks, and limited access to financing for many specialized SMEs.

That said, industrialization is not intended to fully replace traditional construction. Both approaches will need to coexist. Not everything can-or should-be industrialized, and not every project benefits from the same level of prefabrication. The key lies in identifying, based on technical expertise and a deep understanding of each project, where industrialized solutions can deliver the greatest value.

The sector's transformation will not happen overnight, but it is well underway. Scaling industrialization wherever it makes sense is essential to improving productivity, meeting societal needs, and moving towards a more sustainable, safer, and more attractive construction industry. Ultimately, the goal is to build better-not just faster.
