A comprehensive renovation of an urban property rarely goes wrong due to a lack of ideas. It goes wrong when decisions are passed on to the building site too late, when trades overlap without coordination, or when a detail designed for the plans is not executed precisely. Trends in industrialised construction address this problem: they transfer part of the work to a controlled environment to improve quality, predictability and tidiness on site.

It is not a question of turning architecture into a catalogue of repetitive modules. When properly planned, industrialisation allows for exactly the opposite: devoting more thought to the design, resolving issues earlier and executing the work with less improvisation. For a home, a hotel or a restaurant, this difference affects both the timetable and the final experience of the space.

Industrialised construction is no longer synonymous with standard prefabricated building

For years, industrialised construction was associated with rigid, temporary or technically aesthetic solutions. That perception is changing. The evolution stems not only from new materials, but also from a more precise way of coordinating design, manufacturing and assembly.

Today, a lightweight structure, a façade, a bathroom unit, a kitchen, a storage system or a staircase can all be industrialised. Each component has a different degree of repeatability and customisation. The key is not to industrialise everything, but to identify which parts of the project truly benefit from doing so.

In a flat with a complex layout, for example, a wet room unit manufactured to exact dimensions can reduce issues with plumbing, cladding and installations. Conversely, a bookcase that follows an irregular wall or a hallway with a unique geometry may require a more bespoke approach. Bespoke design does not mean making every element in the slowest possible way.

Trends in industrialised construction that are transforming projects

Hybrid systems: precision where it adds value

The most interesting trend is not the fully modular home. It is the hybrid system. It combines elements produced in the workshop with solutions carried out on-site, adapting the method to the conditions of each building.

In refurbishment, particularly in Barcelona, this combination is significant. Existing structures, uneven floor levels, load-bearing walls or narrow access points demand flexibility. Panels, joinery, technical fittings and bathrooms can be manufactured whilst the site is being prepared, but a thorough assessment of the building remains essential. Industrialisation does not eliminate the need for architectural direction: it heightens the requirement to define it clearly from the outset.

Bathrooms and kitchens as coordinated technical units

Wet rooms bring together services, waterproofing, ventilation, fittings and finishes. They also account for a large proportion of the issues encountered on a building site. This is why industrialised bathrooms and high-precision kitchen systems are gaining prominence.

We are not necessarily talking about installing a complete prefabricated unit. Sometimes the innovation lies in manufacturing frames, worktops, cladding panels or installation modules with controlled tolerances. The result can be understated and fully integrated into the project’s aesthetic: natural stone, wood, lacquered metal or seamless surfaces. What is visible remains design; what changes is the quality of what lies hidden.

In high-end hotels and holiday apartments, this approach proves particularly useful. Repeating a well-designed technical solution helps maintain a consistent identity across rooms and reduces installation times. But repetition must be intentional. A hotel does not need to look like a series of identical units if its concept calls for variation, atmosphere and local character.

Lightweight façades and improved energy performance

The building envelope is another major area of development. Façade panels, external insulation systems, high-performance joinery and shading solutions can be manufactured with greater precision before reaching the building site.

The advantage is not just speed. A well-designed façade determines thermal comfort, light intake, privacy and energy consumption for decades to come. In Mediterranean climates, where solar radiation and summer overheating are just as important as insulation in winter, the choice of glazing, air gaps, louvres and sun protection must be tailored to the actual orientation of each home.

Industrialisation does not mean applying the same panel to every façade. It means designing a family of solutions capable of responding precisely to different orientations, openings and rhythms.

Digital design to build with less uncertainty

Industrialised construction relies on reliable information. Three-dimensional models and digital coordination enable the detection of clashes between the structure, ductwork, lighting, air conditioning and fit-out before a component is manufactured.

This process is less visible than a finished façade, but it has a direct impact on quality. When a light fitting, an air return grille and a suspended ceiling are co-ordinated before construction begins, the space gains visual clarity. When such issues are resolved on the fly, unnecessary access hatches, forced junctions and loss of headroom often arise.

In interior design projects, this precision is crucial. Architecture is not perceived solely through grand gestures. It is also perceived in a properly aligned joint, a flush-fitting door, a kitchen without discordant elements, or integrated lighting that complements the space without overwhelming it.

Materials with lower environmental impact and greater traceability

Waste reduction is one of the standard arguments in favour of industrialised construction. Workshop-based manufacturing allows for optimised cutting, controlled material usage and a reduction in the offcuts typical of conventional building sites. However, sustainability considerations cannot stop there.

The origin of the materials, their durability, the possibility of dismantling and maintenance, transport distances, and the building’s performance once occupied are all important. An industrialised component that requires long-distance transport or cannot be easily repaired is not automatically a better option.

Engineered timber, recycled steel, cladding containing reclaimed materials and dry construction systems all have potential, provided they are used with technical expertise. The choice must take into account fire resistance, acoustics, moisture, ageing and suitability for the intended use. A high-turnover restaurant does not have the same requirements as a private bedroom.

What the client stands to gain and what they must decide beforehand

The main advantage for the client is predictability. With a well-developed design phase, it is possible to define costs, materials and timescales more clearly. This also reduces the need for urgent decisions on site, which often drive up costs or compromise the quality of the finishes.

Conversely, there is less scope for changing elements once manufacturing has begun. If a decision is made at the last minute to alter a layout, relocate a service or replace a cladding, the impact may be greater than in a completely traditional build. Industrialised construction rewards early decision-making and penalises indecision.

That is why it works particularly well when the client is involved from the outset in the issues that truly define the project: how they experience the space, what level of maintenance they are prepared to accept, what atmosphere they are seeking, and what their priorities are in terms of budget, timeframe and uniqueness. A bespoke project is not about choosing from an endless array of options. It is about making the right choices.

A common scenario: renovating without turning the site into a live-in building

Let’s consider a family home in an established building. The project involves reorganising the living area, upgrading services, extending the kitchen and improving acoustic comfort. If a large proportion of the kitchen fronts, cupboards, panelling, doors and technical fittings are measured and manufactured in advance, the time taken for on-site assembly is significantly reduced.

The demolition, compliance and adaptation phases do not disappear. However, the noisiest work is concentrated, preventing the home from becoming a makeshift workshop for months on end. Ultimately, the value does not lie in showcasing that something was prefabricated. It lies in the home being perceived as coherent, serene and designed with its inhabitants in mind.

At FFWD Arquitectos, we see this approach as a design tool, not as a rigid aesthetic. Each system must serve the layout, the materials and the way people live or entertain guests within a space.

The right question is not whether to use prefabrication, but what to prefabricate

Not all projects require the same level of prefabrication. A new-build detached house, with generous access and a repeatable geometry, can benefit from highly advanced structural and building envelope solutions. A renovation of an old flat may achieve better results by industrialising only the joinery, furniture, installations or wet areas.

It also depends on the budget and the timeframe. For a commercial opening with a fixed date, reducing construction time may justify a greater investment in coordination and off-site manufacturing. For a home with a high proportion of bespoke craftsmanship, it might be better to reserve industrialisation for the technical elements and concentrate manual work on the finishes that give the project its identity.

The best industrialised construction does not impose a system on the space. It stems from the space itself, its use and its boundaries. When the technical approach is put at the service of this interpretation, the project ceases to be a succession of unforeseen events and becomes what it should be: the precise execution of a good idea.
