Enclosure

Definition

Enclosure is Foucault's term for the spatial strategy of disciplinary power: the delineation of a closed, controlled territory within which individuals are distributed, observed, and regulated. The asylum, the clinic, the prison, the barracks, and the factory are the classic architectural forms of enclosure — each a "protected place of disciplinary monotony." For architecture, enclosure is not merely a physical wall but a spatial technique that produces docile bodies by fixing them in place, partitioning them from others, and subjecting them to constant visibility. Fontana-Giusti shows that while architectural appropriations of Foucault have often focused narrowly on enclosure architecture, his thought has broader spatial implications for knowledge, bodies, and urban space.

Key Thinkers

• Michel Foucault — enclosure as a technique of disciplinary power; the spatial fix for producing docile bodies.
• Gordana Fontana-Giusti — cautions against limiting Foucault's architectural relevance to enclosure architecture alone.

Related Concepts

• Discipline — enclosure is the spatial precondition for disciplinary techniques.
• Panopticon — the architectural model that perfects enclosure by making visibility automatic and continuous.
• Space — enclosure is a historically specific spatial strategy, not space as such.
• Power — enclosure is one way that power operates spatially to produce subjects.

• Ultrasuede (Wagner 2002/2006) — the enclosure thesis's fullest painterly-brokered case: Baldwin's Si Newhouse bedroom, 'covered in brown velvet, "a cave"' (p. 384), where 'the interiority of the room's soft enclosure found its visual foil in the two color field paintings in which the depth was as hermetic as the paintings were introspective' (p. 384) — enclosure described as interiority, softness and depth at once. Wagner's reading of Greenberg and Newman gives the concept its pictorial double: Greenberg's 'openness' of color field painting is architecturally legible 'in terms of enclosure, interiority and delimitation' (p. 384), and Newman's 'space-dome' ('the vertical domelike vaults encompass him to awaken an awareness of his being alive in the sensation of complete space,' quoted p. 384) is a painted enclosure the viewer inhabits — enclosure as the spatial content of modern painting. The architectural realization absorbs the paintings floor-to-ceiling so that 'the architectural space of the room was subsumed by the pictorial space of the pictures' (p. 384) — enclosure and image-space fused, the type-case of the enveloping interior.

• Movement and Myth (Croft 2000/2006) — the domestic enclosure register: the Schröder House's flexible interior as enclosure without walls — "The Schröder House's mythology might place an emphasis on a pioneering form of modern free living, but the reality is about control, not freedom. It could even be said to resemble life in prison, with its proscribed actions at proscribed times" (p. 75); the editors' framing that changing family realities "force spatial issues of segregation and enclosure" (p. 75). Enclosure achieved not by Foucault's fixed architecture but by the occupants' own nightly re-enclosure — "proscribed actions at proscribed times" is the timetable-discipline of the prison carried into the modern home's reconfiguration ritual. See privacy, schroder-house, partition-of-space.
• Towards a Feminist Poetics: Infection in the Sentence (Gilbert & Gubar 1979/2006) — enclosure prescribed as therapy: Gilman's The Yellow Wallpaper as the paradigmatic enclosure case. The room is a rented "large garret room in an 'ancestral hall'"; its furniture of enclosure is explicit — "rings and things" in the walls, "really the paraphernalia of confinement, like the gate at the head of the stairs, instruments that definitively indicate her imprisonment" (p. 123). The enclosure is not penal but medical — the "rest cure" of a "censorious and paternalistic" physician-husband, with writing forbidden — and its extension is bodily: the confined woman enclosed "in the 'infected' house of her own body," the trope that "transforms her into a version of the glass coffin herself" (p. 122). Where Foucault's enclosure produces docile bodies by visibility, Gilman's produces the madwoman's double by exclusion — the enclosure's product is the figure that peels it off ("before morning we had peeled off yards of that paper"). See house-body-equation, the-madwoman, mutedness, Power and Space (Position P).
• Woman's Domestic Body (Gordon 1996/2006) — enclosure's possessive register, in fiction: Edith Wharton's interiors that annex their inhabitants. Her "fictional female characters… came to share physical traits with their houses, or who changed themselves to suit those houses more perfectly. Rooms took 'possession' of these women; a house had an 'almost human power to command.' Once the heroines had been so taken over by those spaces, Wharton implied, leaving them would be 'tantamount to self-annihilation'" (p. 128). The register adds to the page's archive a non-institutional enclosure: not Foucault's walled institution, not Gilman's prescribed room, but the conflated enclosure — the room that owns the woman because the culture has made the woman the room (house-body equation, woman-as-decoration). Enclosure here binds by identity, not by wall or prescription: leaving the interior is "self-annihilation" because leaving the interior is leaving the self it encloses. See Power and Space (Position Q).
• Inside-out and outside-in (Vanucci 2018) — the primitive register: enclosure as the envelope's first and most fundamental act — "In its most primitive form, it protects the interior from the surrounding hostile exterior environment and provides a shelter" — the oldest enclosure not Foucault's monitored institution but the sheltering skin: "the oldest and most fundamental architectural element." The register's contemporary escalation re-poses enclosure as active conditioning rather than passive protection: the envelope "controls the internal environment," its difference-register (temperature, humidity, light, pressure) making "the interior controlled environment of architecture different from the surrounding environment" — and the hostile exterior itself becoming one more input the performative envelope negotiates. Enclosure here is the interior's birth-condition (cf. the grotto's "inherent interiority") upgraded to a continuous environmental operation. See performative-envelope, hermetic-seal.
• Topology and interiority: Folding space inside (Voordouw 2018) — the eroded register: enclosure as the capacity being lost. "Interiority is increasingly eroded in contemporary architectural practice; this enclosure has been methodically worn away"; "the hybridity and ambiguity of programmatic thresholds have undermined the ability to define and enclose space; yet we reside inside." The erasure is doubled — facade erosion from outside, openness within ("'Open space' is increasingly synonymous with the outside") — and its instrument is the topological surface, where "the continuity of the surface prevents the (programmatic) definition of the interior and the porosity prevents its (spatial) enclosure." The register's programme is enclosure's deliberate restoration without its totality: "the interior must be demarcated, and the exterior must be defined as something 'out there'" — "retain the porosity but rescind the ambiguity." Enclosure here is not Foucault's technique (power), the envelope's protection (Vanucci), or the seal's totality (McClure), but the demarcating capacity whose loss produces an architecture without interior. See topological-interiority, threshold-to-gradient.
• Inside Fear: Secret Places and Hidden Spaces in Dwellings (Troutman 1997/2006) — the enemy-within register, enclosure's promise turned on itself: "Within the fortress walls, we believe ourselves safe from whatever lies without, but what of what lies within those walls – what is within the locked cabinet?" (p. 356) — the nested enclosure (land → fortification → town → keep → tower → attic → eaves → chambers → cabinets → locked cabinet) securing against the outside only by multiplying the inside's unsecured depths. Enclosure here does not discipline from without (Foucault) or protect from without (Vanucci) but concentrates the unknown within: each added wall makes the interior deeper and less surveyable, ending in the ellipsis. The register gives the page its limit-case: the enclosure whose danger is what it contains. See hidden-spaces, fear, concealment.
