Modern methods of construction are reshaping how Irish architects approach building design, according to Rory Ryan, director of Ryan + Lamb Architects. He argues that the profession must learn the language of these techniques at the concept stage, not wait until later phases. The approach delivers unprecedented precision, speed and design freedom, allowing architects to explore complex forms without compromising constructability.
Understanding the breadth of modern methods
Many practitioners assume the approach only involves large prefabricated modules, but it actually covers seven categories. Common tools such as point‑cloud surveys, drone mapping and factory‑made components all fall under the same umbrella. Even a standard window qualifies as a product designed, engineered and built in a controlled environment before being installed on site. Architects are already using categories 2, 3, 6 and 7, often without recognizing them as part of MMC.
These digital tools have become routine in contemporary practice, yet the industry often fails to recognize them as part of the same system. By treating the method as a continuum rather than a niche, architects can see its relevance across most projects. Point‑cloud and drone data feed directly into BIM models, creating a seamless workflow from survey to fabrication.
Why early adoption matters
Ryan notes that a recurring pattern emerges in his annual lectures for the RIAI: architects are curious but hesitant. Some fear a loss of creativity, while others simply do not know where to begin. The real obstacle, he says, is a lack of understanding about what the technique can achieve. He stresses that MMC is an opportunity rather than a threat, amplifying design intent when introduced early.
He recalls a recent presentation where a colleague asked whether a building using insulated concrete forms required a separate thermal model. The answer was no; the product’s performance is pre‑certified, making it more likely to be installed correctly than a traditionally built wall. The CE certification of the system guarantees its thermal behaviour without additional modelling.

When designers view the process only from the construction end, opportunities disappear. In one case, a client asked for volumetric delivery after planning permission had already been granted. Adjusting the design would have meant a new application, and the chance to speed construction was lost. Planning constraints often make late‑stage volumetric changes impractical.
Had the method been considered at the concept stage, the project could have been split into four units, reducing on‑site build time from nine months to three. That illustrates how early engagement can dramatically affect schedule and cost. A three‑month on‑site programme versus nine months represents a significant efficiency gain.
Architects should therefore ask on day one whether any part of a design could benefit from panelised systems, hybrid solutions or factory‑controlled components. The earlier the decision, the more design freedom remains. Early questioning opens the door to hybrid approaches that blend MMC with conventional methods.
When the approach is adopted early, creativity often flourishes. A recent school design placed resource rooms into circulation corridors, creating sheltered niches for students. The result was a hybrid building that combined efficiency with expressive architecture. This mirrors the Bauhaus era’s reimagining of material systems to expand architectural language.
In this middle segment of the story, it seems clear that the shift will not happen overnight. If firms start experimenting with factory tours and integrate digital models sooner, the learning curve should flatten, and the industry may avoid the pitfalls of late‑stage retrofits. The upside is tangible, but it will require a cultural change as much as a technical one. Early exposure to the workflow reduces uncertainty and accelerates adoption.

Factory advantages and client benefits
Building components in a factory eliminates many variables that plague on‑site work. Weather delays, inconsistent labor skill levels and material damage are largely removed. Digital data replaces traditional drawings, allowing for tighter tolerances and reduced waste. The use of BIM‑driven manufacturing ensures each element fits precisely, minimising on‑site adjustments.
Clients gain cost certainty, schedule predictability and consistent quality. Architects, in turn, spend less time troubleshooting and more time refining the design. The environment also supports Six Sigma standards, further improving reliability.
Procurement and the path forward
Public authorities often rely on outdated procurement templates that do not accommodate the method’s requirements, limiting participation from capable providers. By contrast, private developers are increasingly adopting the technique after experiencing the uncertainty of conventional construction—missed deliveries, weather setbacks and contractual gaps. Developers have reported issues such as absent blocklayers and delayed concrete trucks, which MMC can mitigate.
Ryan advises architects who are unsure where to start by visiting factories. Observing an assembly line, watching a module come together, and speaking with the people who build these systems can demystify the process more effectively than any lecture. Seeing BIM integration in real time clarifies how digital design translates into physical components.
The shift toward modern methods will likely accelerate as more private projects demonstrate success. When public bodies see the benefits—reduced risk, faster delivery and higher quality—they may adjust their procurement models accordingly.
