Casa LL: How P•A•N Turned a Postmodern Milan Office Into a Home

On the southern edge of Milan — past the concentric rings of the historic centre, out where the city relaxes into industrial flatness — stands the building that would become Casa LL. It was not a promising shell in the conventional sense. A postmodern office structure, the kind of building that accumulated function rather than spatial intention, its floor plan organised around practicality rather than experience. It was the type of building that most architects would approach as a problem to be solved. P•A•N approached it as a premise to be extended.

Filippo Cattapan and Davide Macchi, who together form the Milan-based studio P•A•N, have built a practice that converges academic rigour with built work. Founded in 2022, their interest is not in the gesture but in the logic that precedes it. At 250 square metres, Casa LL is the clearest evidence of this to date: a project in which every decision — every surface left raw, every void held open — can be traced back to a single, consistent spatial argument.

Shaping the Void

The argument is this: that spatial experience is produced not by what is added to a building but by what is withheld from it. P•A•N's intervention in Casa LL reads less as renovation than excavation — a methodical uncovering of what the building could hold once freed from its programmatic history. Walls are not decorated; they recede. Volumes do not compete; they emerge in sequence, made legible by what surrounds them.

"The project's organisational logic was handed over to void and to light — two elements that cost nothing and demand everything."

The result is a floor plan that reads differently at different times of day. Morning light enters and defines one set of relationships between spaces; by afternoon, another. The architecture is not static but calibrated — tuned to the movement of the sun in a way that postmodern office buildings, with their sealed envelopes and fluorescent ceilings, typically are not.

A Material Register That Works

The material palette of Casa LL is deliberate in its refusal of finish. Exposed plaster, bare concrete — surfaces that in other hands might read as unresolved are here deployed with precision, each material placed in relation to light and geometry rather than applied across surfaces indiscriminately. This is the distinction that separates considered rawness from mere austerity.

Raw materials are not monolithic; they perform differently depending on their context. A concrete column in raking afternoon light is not the same object as that column under overcast morning diffusion. P•A•N's work at Casa LL depends on this variability — the material palette is a set of instruments, not a fixed score. The project's lighting selections — Flos, Davide Groppi, Zumtobel — reinforce this logic: each fixture chosen not for decorative effect but for the quality of light it produces against raw surfaces.

Why SILCO HAUS Selected This Project

We selected Casa LL for the rigour of its thinking. What holds our attention is the project's insistence on restraint as a generative condition — the decision to let material honesty carry what decoration might have obscured. This is an interior where chromatic reduction and industrial memory are not negations of richness but its fullest expression.

The tension between the building's office origins and its new residential programme is never dissolved at Casa LL; it is held, made productive, turned into the project's primary spatial charge. The building does not forget what it was. That productive irresolution is exactly the territory SILCO HAUS is built to document.
