Emerging from the logics of industrial production, modularity established itself as a system of standardised, repeatable units, shaping the foundations of modern design through efficiency and control. It begins as a system of order, a way of organising form through repetition, standardisation, and control. Yet in the hands of contemporary designers, this logic is no longer confined to efficiency alone. Belgian designer Pieter Maes approaches modularity as something far more unstable and generative, where units are not simply assembled but composed, and systems become a means of producing variation, rhythm, and spatial tension. Working across furniture and object design, Maes treats modules as both structural and aesthetic elements, allowing repetition to give rise to unexpected forms rather than predictable outcomes. While modularity originated as an industrial strategy grounded in rational production, Maes reinterprets it as a sculptural and conceptual design language. Through his work, modularity shifts from a neutral system of organisation into an expressive tool, where repetition, variation, and system-based thinking actively construct form, space, and meaning.
The twentieth century saw modularity become one of the central logics of modern industrial design, emerging from the need to rationalise production through systems of standardisation and repeatability. At its most fundamental level, modularity is based on the decomposition of complex wholes into discrete, interchangeable units that can be independently produced and subsequently recombined into larger assemblies. This principle transforms design from a process of crafting singular objects into one of constructing systems governed by rules of compatibility, repetition, and interchangeability. In industrial manufacturing and modernist architecture alike, this approach supported broader ambitions of efficiency, control, and scalability, where reducing variability and increasing predictability were essential to managing increasingly complex production processes. Within this framework, modularity operates as an organisational logic rather than an aesthetic one: it structures how objects are conceived, produced, and assembled, prioritizing consistency and functional clarity over formal uniqueness. Yet embedded within this system is a latent formal condition. Once elements are standardised, their recombination inevitably produces variation, revealing that repetition can generate difference as much as uniformity. It is this tension that contemporary design practices begin to activate. In the work of Belgian designer Pieter Maes, modularity is reinterpreted not as a closed system of efficient assembly but as an open and generative framework. Here, modules are not simply repeated or arranged according to predetermined logic; they are composed, allowing spatial tension, rhythm, and instability to emerge through variation within a shared system. In this shift, modularity moves beyond its industrial origins as a mechanism of standardisation and becomes a conceptual and expressive tool, where system-based thinking actively produces form, meaning, and spatial complexity.
In contemporary practice, modularity is no longer restricted to the logic of industrial assembly but increasingly operates as a sculptural and conceptual strategy, where the unit itself carries aesthetic weight. This shift has precedents in post-war art and design, particularly in the approaches of artists such as Sol LeWitt and Donald Judd, where repetition, seriality, and industrial fabrication were used to showcase structure. In the work of designer Pieter Maes, modularity is a compositional system rather than a fixed method of construction. His Strata Modular Corner, part of the Strata pieces, demonstrates this approach, where the corner element is treated as a generative node that reorganises the behaviour of the entire system. The work appears as a stacked, stratified arrangement of repeated units that shift subtly in alignment, thickness, and spacing, producing a sense of gradual modulation rather than uniform repetition. The modular structure is visibly articulated, allowing the viewer to read both the individual unit and the larger spatial field simultaneously. This oscillation between part and whole is central to Maes’ approach: the module is never fully absorbed into a total form, but continues to assert its presence within the system.
Through this logic, form is not predetermined but emerges through the internal rules of combination. The corner piece, in particular, becomes a point of intensification where repetition bends into variation, producing tension, depth, and directional movement. Rather than organising production in a purely functional sense, modularity in Maes’ work operates as a generative framework in which systems actively construct form. The result is a sculptural language where repetition is not neutral but productive, and where structure itself becomes the primary site of expression.
