Bio Sketch

Johan Voordouw is a Canadian architect and educator at the Azrieli School of Architecture & Urbanism, Carleton University, Ottawa (web-verified via OpenAlex: affiliation listed 2014–2015; the chapter's note 6 thanks Carleton mathematics colleagues for correspondence on topology's history). His research joins computation and representation: hybrid analog/digital drawing — the Weerkas project of twelve intaglio etchings produced from digital models for the 2014 International Architecture Biennale Rotterdam (exhibited at the Kunsthal), published as "Digital Etching – An Alternative Approach to Drawing" (eCAADe 2014) and "Hybrid Representation: Intaglio Etching of Digital Models" (International Journal of Architectural Computing, 2015) — and the changing status of the line in digital production ("Digital Line: Architecture's Expanding Thread," The Plan Journal, 2019). His contribution to Marinic's Interior Architecture Reader extends this digital-geometric research to the interior: "Topology and interiority: Folding space inside" (Ch. 37) argues that interiority — "an internalized centralization of space" — has been methodically eroded by the topological surface's porous gradient, and proposes re-establishing interiority through topological geometries that fold "surface to form space."

Key Works

"Topology and interiority: Folding space inside" (2018) — Chapter 37 of The Interior Architecture Reader (ed. Gregory Marinic): the threshold-to-gradient diagnosis, the topology historiography (Banham to Spuybroek), and the programme to re-establish interiority through enclosed topological geometries.
"Digital Etching – An Alternative Approach to Drawing" (eCAADe proceedings, 2014) — the Weerkas intaglio-etching project: an analog method of intaglio etching via digital/computational means, countering "nostalgic representation" by re-creating past modes of production through a "pluralistic" combination of three-dimensional modelling and two-dimensional drawing.
"Hybrid Representation: Intaglio Etching of Digital Models" (International Journal of Architectural Computing 13.3–4, 2015) — the published development of the Weerkas digital-to-plate pipeline (Rhino, Grasshopper, 3D Studio Max, AutoCAD; photo-transfer to polymer plate).
"Digital Line: Architecture's Expanding Thread" (The Plan Journal 4.1, 2019) — the argument that digital production has shifted lines "as trace" towards a "spatialized" thread, moving away from orthographic and perspective modes of representation through three embedded conceptions: model, diagram, notation.

Key Concepts

Concepts associated with this author that have pages in this wiki:

topology — the chapter's central concept: topology's architectural career from Banham's 1955 subservient usage through Deleuze's fold to computational surfaces, and its mathematical contradictions with architecture (scaleless, measureless, surface without space).
topological-interiority — the chapter's positive programme: interiority as "an internalized centralization of space," re-established by folding that "deforms surface to form space" (the enclosed topology of H2Oexpo and the Teshima Art Center).
threshold-to-gradient — the chapter's historical-diagnostic concept: the boundary's past-century evolution "from a defined threshold to a porous, ambiguous gradient," and the gradient identified as "the zone that prevents knowing."
interiority — the chapter's term of art: spatial-centralizing (not psychological) interiority, eroded from two directions (facade erosion from outside; openness within).
digital-architecture — the medium: topology as "an inherent result of the 'digital revolution'"; Carpo's "revolution with no identifiable history and no predetermined destination"; the computation-widened gap between parametrically defined form and secondary space.

Relevance to the Core Research

Voordouw matters to this wiki's interior-architecture cluster as the Reader's geometry-theorist of interiority: where Vanucci's chapter (Ch. 32) makes the envelope the agent of interiority and Anderson & Lovell-Anderson's (Ch. 18) formalizes surfaces as volume-makers, Voordouw supplies the diagnosis of what happens when the surface becomes continuous — interiority erased. His threshold-to-gradient evolution gives the wiki's boundary cluster (boundaries, thick-edge, hermetic-seal) its historical engine: the twentieth century as the boundary's transformation from threshold to gradient. His Dom-ino critique ("While it is variable, it remains immobile") is the sharpest internal challenge to the wiki's dynamic-architecture cluster (static-vs-dynamic-architecture), and his historiographic correction — topology as "a continuation of postmodernism, not a 'Baroque' development of modernism" — re-dates the fold's lineage against the Lynn/Deleuze Baroque story that Hannah's chapter (objectile) also scrutinizes. For the Researcher's performance-model and production-oriented-practice interests, the chapter is the geometric counter-register: the topological surface as the form that produces neither event nor effect, only continuity.
