As Europe faces a worsening housing shortage, a new generation of construction robots is being pitched as a solution, but how realistic is the idea, and what does it mean for sustainability, workers, and the industry as a whole?
Rethinking the Way We Build
Housing shortages aren’t new, but in parts of Europe (including the UK) they’ve now reached critical levels. Spiralling costs, strict planning rules, and a growing mismatch between supply and demand have pushed home ownership further out of reach for many. At the same time, the construction sector is facing a crunch of its own.
While other industries have embraced automation and innovation, it seems that construction has remained largely unchanged. For example, today’s building sites largely feature bricks, mortar, manual labour, just as they would decades ago (although there are modern hoists and plant machinery). Arguably, the result is that building is still relatively slow, and is suffering from higher costs and dwindling productivity.
One telling statistic is that, although since 1945 productivity in manufacturing has increased more than eightfold, in construction, it’s only risen by just 10 per cent, and in some cases, has actually gone backwards. For example, building a single-family home now takes longer and costs more than it did 50 years ago, even after adjusting for size. Labour shortages are also compounding the issue. In the UK, the number of bricklayers recently hit a 25-year low, with a third expected to retire within the next decade.
This stagnation is feeding into the wider housing crisis. The shortage of skilled workers delays projects and drives up costs. Meanwhile, urban populations continue to grow, and government targets, such as the UK’s pledge to build 300,000 new homes a year, are consistently missed.
It seems, therefore, that the response by some technologists to propose a different approach may be welcome at this point, i.e. rather than simply trying to build more with the tools that have always been used, suggesting that a total rethink on building is needed.
Robot Builders?
The newest suggestion by some scientists is that autonomous robots, guided by AI and precision software, could take on repetitive and labour-intensive tasks, e.g. laying bricks, moving materials, and even assembling entire walls.
The idea is that robots could help us build faster, more affordably, and with less waste. This is a vision that blends technological ambition with an urgent social need, but the real question is whether this kind of innovation can change things for the better, or whether it’s another idea that will get stuck at the planning stage.
Bricklaying
Amsterdam-based startup Monumental is among those exploring whether robotics could reshape construction. The company has developed a suite of autonomous, electric robots designed to handle one of the most repetitive and labour-intensive tasks on site, i.e. bricklaying.
The system combines:
– Ground-based electric robots that move materials around a site.
– Small crane-like arms that place bricks and apply mortar.
– Computer vision and sensors to track exact positioning.
– A software platform, called Atrium, that maps the environment and guides the robots with millimetre precision.
Each robot is connected to a central coordination system that plans movements, detects site changes, and ensures accuracy in real time. Before building starts, a full 3D scan of the site is taken and aligned with digital building plans. From there, the robots get to work, layer by layer and brick by brick.
Work Alongside Human Builders
It should be noted here that the system is actually designed to work alongside human builders rather than to replace them. For example, labourers still prepare the site, oversee quality, and step in where needed. Monumental calls its approach “software-defined construction”, aiming for flexibility and integration rather than wholesale automation.
Does It Work?
So far, Monumental reports that the robots have built house façades, retaining walls, and other real-world structures across the Netherlands. For example, in 2023, the system completed its first full-scale 15-metre wall, and the company says performance has improved significantly with each iteration, helped by rapid software and hardware updates based on field testing.
The real aim, according to co-founder Salar al Khafaji, is to lay the groundwork for much broader automation, i.e. rather than just bricks, the robots also being able to work with concrete blocks, window frames, door frames, roofing elements, and more.
For now, Monumental appears to be focusing on reliability and practical deployment. The system is offered as a service where clients simply specify the bricks and mortar, and Monumental delivers the finished wall.
Who Else Is Building With Robots?
Globally, construction robotics is actually gaining momentum. In the US for example, Built Robotics offers autonomous trenching and earthmoving systems for infrastructure projects. ICON, known for its 3D-printed homes, has built houses for disaster relief and was recently awarded a $57 million NASA contract to develop construction tech for the Moon.
In Japan, the Shimizu Corporation is experimenting with robots that can handle everything from interior finishing to welding. Closer to home, the UK’s Construction Innovation Hub is exploring off-site manufacturing techniques that integrate robotics for modular building components.
Each approach varies, but the end goal is to make construction faster, more precise, and less dependent on scarce labour.
What It Could Mean for Sustainability
As well as being slow and expensive, traditional construction methods are also environmentally costly. According to the Global Alliance for Buildings and Construction, construction and building operations are responsible for nearly 40 per cent of annual global carbon emissions!
Robotic construction could offer several environmental benefits, such as:
– Electric robots like Monumental’s generate zero on-site emissions and reduce noise pollution.
– Precision placement, which can reduce material waste and rework.
– Faster builds, thereby lowering the overall energy footprint of each project.
By reducing reliance on diesel-powered machinery and minimising disruption, robotic systems could also be better suited to urban infill projects, where sustainability and community impact are closely scrutinised.
That said, the broader carbon impact also depends on material choices, energy sources, and supply chain factors, which robots alone can’t fix.
How Ready Is the Technology?
Despite the progress, fully autonomous building sites remain a long way off. Most current systems (including Monumental’s) focus on specific, repetitive tasks such as bricklaying or trench digging. Complex structural work, finishing, and systems integration still require human expertise.
Performance metrics are still emerging, but Monumental’s field projects suggest the technology is edging closer to commercial viability. The company claims its robots can build continuously, avoid common errors, and scale up with multiple units on one site.
Crucially, it has opted to work within existing construction norms, using conventional bricks, mortar, and pricing structures. This has helped reduce resistance among cautious builders, though long-term data on cost savings and productivity is still limited.
Implications for the Industry and Workforce
With labour shortages biting across Europe (19 countries were reporting a bricklayer shortage in 2022), automation may fill some urgent gaps. In the UK, where one-third of bricklayers are due to retire in the next decade, demand is unlikely to ease.
However, using robots raises familiar questions around job displacement. Even if robots assist rather than replace workers, fewer may be needed on site. That could reshape the training landscape, shift demand towards tech-savvy roles, and put pressure on traditional trades.
For construction firms, although automation could help meet delivery targets, especially for large-scale housing projects, costs, reliability, and integration still weigh heavily. Monumental’s “robot-as-a-service” model, which avoids capital investment and ties pricing to output, is one attempt to lower that barrier. Whether others will follow remains to be seen.
Governments, Policy, and the Housing Crisis
In places like Monumental’s home country, the Netherlands, where the government has committed to building one million homes by 2030, robotic construction may offer a helpful lever, but not a panacea.
In the UK, housing policy remains politically fraught, and delivery targets have repeatedly been missed. If robotic systems can offer faster build times, safer sites, and lower carbon footprints, they could become part of the toolkit for councils and developers alike.
Still, regulation, standards, and public trust are likely to play a major role. Construction robots may be technically impressive, but mass adoption will depend on how convincingly they can be integrated into real, everyday projects.
What Does This Mean For Your Organisation?
It seems there’s no single fix for Europe’s housing crisis, but the slow pace and inefficiency of traditional construction methods have clearly become part of the problem. As this article has highlighted, robotic systems like Monumental’s offer one possible route towards building more homes, more quickly, and with fewer emissions. What’s striking is not just the innovation itself, but the way it’s being packaged, i.e. pragmatic, incremental, and designed to slot into existing workflows rather than disrupt them completely.
In the UK, developers under pressure to meet housing targets may find robotic services attractive, particularly for repetitive or labour-intensive parts of the build. Construction firms willing to engage with these tools early on could gain a competitive edge, especially as skilled labour becomes harder to find. Also, tech providers, equipment suppliers, and training organisations may see growing demand for systems integration, on-site support, and workforce upskilling.
That said, the adoption curve is unlikely to be smooth. Much depends on how well these technologies perform under real-world pressures, how quickly costs come down, and whether builders, regulators and insurers are willing to adapt. Jobs will change (i.e. some may go, others will evolve) and this raises big questions for education, employment policy, and worker protections.
For policymakers and local authorities, there will need to be a balance between embracing robotic construction to help unlock stalled housing developments and support sustainability goals, and rethinking procurement, planning frameworks, and public trust in new technologies. If done carefully, it could support a more resilient and forward-looking housing system. If rushed or poorly managed, it may risk further complicating an already difficult landscape.
What’s clear is that the conversation has moved on from theoretical hype to practical possibility where, although robots aren’t going to replace the construction industry, they may quietly start rebuilding how it works.
