Why do architects hesitate about modular construction?
Architects don't reject modular technology. However, they do have reservations about a delivery model in which design, production, and assembly are handled by separate companies. These concerns can be addressed through an integrated model, in which one partner - UCUBER - is responsible for the entire process. - PIOTR KĘSEK, DIRECTOR OF THE ENGEENERING AND DESIGN DPT AT UCUBER
Modular construction shortens lead times, shifts quality control to the factory environment, and ensures that delivery dates are not dependent on weather conditions or the availability of labour on site. Despite this, many architects remain sceptical about this method. At UCUBER, we have collaborated with architects from across Poland, France, the UK, the Netherlands and Scandinavia. We are familiar with these concerns from our own experience – and we know how to systematically address them.
What are the main barriers for architects in modular design?
The 6 most common barriers are: a reversed project timeline, fragmented responsibility across multiple parties, factory-grade documentation requirements, geometry constraints, MEP coordination at module joints, and a shift in the architect's role. Let's take them one by one.
1. A reversed project timeline - decisions come earlier
In a traditional construction process, many decisions can be deferred: material selections are refined during procurement, details are resolved through site supervision, and some issues are simply "worked out on site." In modular technology, that flexibility disappears.
Before production starts, the following must be locked in:
- the module breakdown and structural grid,
- MEP routing and crossings at module joints,
- partition build-ups with acoustic and fire performance parameters,
- transport dimensions and delivery logistics,
- the installation sequence on site.
The design must be production-ready, not merely permit-ready. That requires engaging manufacturing knowledge much earlier — and this is exactly the knowledge UCUBER brings to a project from the first sketch.
2. Fragmented responsibility - too many parties, too little alignment
A typical modular project on the market involves an architect, a structural engineer, a general contractor, and a module manufacturer — four entities, four contracts, four sets of priorities. Usually at least one of them is delivering a modular project for the first time.
The consequences of fragmentation include:
- scope gaps and diluted responsibility,
- design decisions made without knowledge of their manufacturing consequences,
- redesign at a stage when every change costs real money and weeks of schedule.
How we solves it: we collapse that chain into a single point of responsibility. Execution design, steel module production, and installation sit within one company, under one contract and one project lead.
3. Factory precision instead of site tolerances
A module's steel frame is fabricated in a production hall to workshop accuracy measured in millimeters — and the documentation must match that rigor. An execution design for modular technology has to anticipate manufacturing tolerances, assembly sequencing, inter-module connections, transport bracing, and even temporary protection of partitions during shipping.
What "sorts itself out" on a traditional construction site must be drawn here. The required level of BIM detail is simply higher than in a conventional execution design.
How we solves it: UCUBER has an experienced in-house team of architects and structural engineers who work with modular steel technology every day — they know the manufacturing tolerances, the assembly sequences, and the transport requirements, and they anticipate them in the documentation.
4. Geometry constraints - real and imagined
Road transport dictates module dimensions, the structural grid disciplines spans, and module joints introduce double walls. Against this backdrop, architects fear that modular technology will force significant compromises on the elements that define a building's character: generous open-plan spaces, unconventional floor plans, and distinctive facades.
Some of these constraints are real and must be known from the first sketch. A well-designed modular building doesn't reveal the logic of prefabrication.
5. Building services crossing module boundaries
HVAC, plumbing, and electrical systems that cross a module joint need a connection point, service access. In a traditional process, the MEP engineer would resolve this during construction. In modular technology, it must be settled before production — an additional layer of interdisciplinary coordination that has to be planned for.
6. A shift in the architect's role
The deepest barrier is often unspoken: in a modular process, the architect stops being the sole author and becomes part of a system in which production engineers, logistics, and installation teams also have a voice. For many practices, that isn't a procedural change — it's a change of professional identity.
We understand this. That is why UCUBER's collaboration model is built so that authorship of the concept stays exactly where it belongs — with the architect.
