Kit of Parts

For over a century, modular construction has promised to solve housing. Build faster, cheaper, more efficiently. Repeat the parts, reduce the variables, control the cost.

The promise is real enough. Prefabrication can reduce waste, improve quality, and accelerate delivery. But something is lost when efficiency becomes the only objective. The kit of parts, treated as an end in itself, tends toward a particular outcome: housing that is fast to produce and slow to inhabit. Homes that function but don't belong. Buildings that could be anywhere, and therefore feel like nowhere.

The problem is not modularity. It is the assumption that repetition and richness are opposites.

Consider how modular systems are typically deployed. A component is developed, tested, and approved. It becomes the unit of production. Everything else — site, orientation, relationship to street, spatial generosity — is adjusted to suit the unit rather than the other way around. The module disciplines the design rather than enabling it.

A different approach starts with typology rather than component. The courtyard, the bar, the L-shape, the split-level — these are not arbitrary gestures but spatial structures that have proven their capacity to generate life across centuries and climates. When a modular system is organised around a typological logic, something different becomes possible. The components serve the spatial idea rather than replacing it. The repetition operates at the level of the part, not the whole.

This is what we mean by a kit of possibilities rather than a kit of parts. The individual component may be standard — a panel, a module, a structural bay — but the assembly is not. Variation is not applied as surface decoration; it is embedded in the logic of how parts combine. A courtyard is not a leftover space between modules. It is a generator: of light, air, outlook, and gathering.

Material matters here too. Prefabricated elements can carry texture, weight, and character. Corrugated metal, timber battens, raw concrete: each ages differently, holds light differently, speaks differently to its setting. The decision to standardise a component need not mean standardising its surface or its atmosphere.

What makes the difference is curation. Generative tools can now produce hundreds of massing iterations in an afternoon — testing courtyards, orientations, section cuts, and configurations far faster than a drawing board allows. But this abundance does not produce architecture. It produces possibilities. The architect's task is to recognise which possibility belongs: which typology suits the site, which arrangement creates the right relationship between spaces, which assembly carries the right atmosphere.

A kit of parts delivers units. A kit of possibilities, curated with care, delivers places.
