Alteration

Definition

Alteration is David Erdman's design concept for the twenty-first-century interiorized city: the "restrained, fine grained, and interiorized" reconfiguration of an existing object's interior, distinguished from both adaptation (the ground-up, whole-system program) and from adaptive reuse as marketing. The concept is defined against its neighbor: "Where adaptation is about objects adjusting to their surroundings, alteration is about reconfiguring the object's interior." Its direction-figure is centripetal: "Alteration could be called a more 'centripetal,' rather than 'centrifugal,' approach to design, one that pulls and tucks architecture into shape, rather than deforms a structure to adjust it to adjacencies." Its object-theory is graded: "Alteration has both the potential to maintain a degree of objecthood, and yet, in itself, is fragmentary and episodic. Altering is an exercise in adjusting select, disjointed areas – not the entire original object." And its promise is the collective object — reconfiguration that can "detach itself from the original object and form new objects, or refashion the original into a new collective object."

The concept's claim is disciplinary as much as practical: because interiors are episodic and autonomous, alteration "builds upon the ideas of adaptation by affronting standardization" and opens "fresh discursive territory" for rethinking the architectural whole — "Can strategies of alteration be pushed close to the disjunctive extreme of fragmentation while maintaining enough cohesion to be understood as forming new types of architectural wholes? Does alteration allow for a way to engage new ways of thinking that embrace, rather than exile, interiors-based work from architecture?"

Distinctions

Alteration vs. adaptation. Adaptation — from the biological models of Kiesler's Endless House and Kurokawa's Nakagin Capsule Tower through to contemporary "adaptive reuse" — is "conceived from the ground up, introducing a comprehensive and whole architectural system into a context," and "the contemporary field of architectural software favors this continuous, smooth, singular, and fully integrated approach." Adaptation strives "ardently for the production of a singular, autonomous whole"; alteration does not.
Alteration vs. reuse-as-marketing. Erdman's blunt audit: adaptive reuse is "used more often as a marketing ploy than a conceptual opportunity" — alteration is the conceptual content that marketing-speak hides. The distinction also widens Hollis's "practice of alteration" (intervening in existing buildings) and Brooker & Stone's remodeling: Erdman's alteration operates at the scale of the object's interior, not the building's shell, and refuses the whole that those retelling-practices still seek.
Alteration vs. the disjunctive fragment. The 1980s disjunctive theories (Deconstruction, Rossi, Tschumi) produced "explosive fields of objects that were syntactically related but conceived as separate autonomous follies" (note 9). Alteration inherits their "agility" but adds cohesion: interventions that "do not remain entirely separate follies but instead form new types of more complex architectural wholes" — the postdigital revival.

The Repulse Bay Complex (the built demonstration)

davidclovers' Repulse Bay Complex renovation (Hong Kong, 2011–2013) — one of the first comprehensive "gut" renovations of a tower in Hong Kong, of an "Arquitectonica 'knock-off'" whose "standardized and homogeneous" towers the brief's interventions would heterogenize — is the concept's proof: "The project illustrates the potential of the disjunctive to produce a new type of spatial fabric that is cohesive yet agile and formed out of a series of disconnected interventions." Each intervention "has its own discrete limits and could not be conceived a continuous whole"; the composite of techniques ("digitally prefabricated construction to algorithmically generated graphic design and coloring techniques") proliferates "specificity, dexterity, and heterogeneity, while avoiding episodic fragmentation." The ensemble's formula is the concept's in one sentence: "The ensemble of interventions never fully integrates or makes the site whole, yet incrementally they produce enough pressure and tension to tether remote and unconnected experiences to one another."

Key Thinkers

David Erdman — the concept's author: interiority-centripetal alteration, the adaptation/alteration distinction, objecthood's degrees, and the Repulse Bay demonstration (2018).
Bernard Tschumi — the disjunctive antecedent ("perhaps most importantly" Architecture and Disjunction) whose fragment-agility alteration inherits and re-couples to cohesion.
Edward Hollis — the prior "practice of alteration" conception (intervening in existing buildings) that Erdman's object-scale version retools.
Friedrich Kiesler & Kisho Kurokawa — the adaptation pole's benchmarks (Endless House 1950; Nakagin Capsule Tower 1972: "biological adaptation to underpin their form, geometry, and massing") (not paged — see log).

Adaptive Reuse — the practice-family alteration re-theorizes: "used more often as a marketing ploy than a conceptual opportunity," "ripe for theoretical expansion and tectonic interrogation – particularly in relation to ideas of interiority."
Interiority — the concept's medium and end: alteration "resituate[s] interiority in architecture"; each technique "invokes degrees of a perceptual interiority."
Objecthood — the concept's object-theory: the whole discussed as "degrees of 'objecthood'" (Fried-derived, perceptual, graded).
Interiorized Object — the concept's instrument: the object whose interior is reconfigured to "pull experience into" it; involutions as "a method of spinning context inward."
The Architectural Whole — the tradition alteration affronts: five hundred years of part-to-whole theory; "new types of wholes" as its replacement program.
Heterogeneous Space — the spatial product: interventions "proliferate a high degree of specificity, dexterity, and heterogeneity, while avoiding episodic fragmentation."
Quasi-Autonomous Interior — the coexistence condition: alteration's cohesion preserves "the semi-autonomy of interiors and exteriors to coexist."
Deconstruction — the disjunctive lineage (MOMA 1988) alteration revives postdigitally.
Topology — the direction-vocabulary: the "topological city" as centrifugal and dying; alteration as its centripetal answer.
Mass Customization — the technological substrate (digitally prefabricated construction; the chapter's AD "Mass Customized Cities" provenance).

Open Questions

Can alteration's "cohesion without integration" scale beyond Hong Kong's GFA-driven, multi-designer development market — or is the concept structurally an economy-specific practice (tenders broken up, "minimize risk by involving more than one designer, style, and brand")?
Hollis's alteration retells the building's shell; Erdman's reconfigures objects' interiors. Are these one concept at two scales, or two concepts that share a name — and which does "alterations and additions" (A+A) work actually deliver?
Erdman asks whether alteration can be pushed "close to the disjunctive extreme of fragmentation while maintaining enough cohesion" — where is that limit? What distinguishes an altered ensemble that tethers experiences from one that merely juxtaposes follies?
If adaptation is "ripe for theoretical expansion" and alteration supplies it, does alteration remain a distinct concept — or does "adaptive reuse" simply absorb it (as it absorbed Hollis's alteration) once the academy catches up?
The concept is built on Fried's perceptual objecthood ("degrees of objecthood") — but Fried's essay was an argument against objects that hold the viewer at theatrical distance. Does alteration's "collective object" escape the theatricality critique Fried mounted, or repurpose it?
