Zeilenbau

Definition

Zeilenbau (German: 'row building') names the Modernist housing layout of the 1930s — "the arrangement of blocks, row after row, as regular as the Zeilen, as the lines on a page of writing" (p. 39) — which Glendinning & Muthesius present as "the most scientific, in fact, the only scientific, layout" of its era. Its doctrine: "strict orientation was the first principle: a block should be aligned from north to south… 'The sun should determine the orientation of houses, not the street'" (p. 39) — free-standing rectangular slabs, independent of the street network, spaced for equal sunlight. Its architect-theory came from Ludwig Hilberseimer and Walter Gropius around 1930: Gropius's arithmetic showed "that increased height allows one to house more people on a given piece of ground… this did not result in less light for the inhabitants" — height buying daylight and greenery, with "a height of between eight and twelve storeys appeared ideal; the worst solution seemed the old tenement blocks of three, four or five storeys, which fell between houses and high flats, with the advantages of neither" (p. 39).

The concept's career in UK public housing: first foothold at Kensal House (1937, "probably the first proper Zeilenbau development in the UK," p. 44), the postwar public canon (Spa Green, Hallfield, Churchill Gardens), then the consensus's collapse under aesthetic criticism ("avoid the ghastly uniformity of six or eight storeys over the whole scene") and the rise of the point block from 1951 — "By 1953, 'point block' and 'slab block' had taken their place in the vocabulary of Modern designers. This meant, of course, an end of the Zeilenbau consensus" (p. 56). Its English permutation: the Unité-derived high maisonette slab (Roehampton Lane Alton West), the Zeilenbau ideal "of a stack of dwellings in a slim block with maximum openings on either side" (p. 78). Its Scottish apotheosis: Dundee's Ardler (1964–66), "the zenith of Zeilenbau: the six 17-storey blocks" (fig. 25.23) — the CIAM mainstream still "straightforward" in Scotland after English designers had repudiated it.

This page requires fuller treatment — created at the Glendinning & Muthesius ingest; the German municipal-estate origins (1920s) and the daylight-science apparatus await further sources.

Key Thinkers

• Miles Glendinning & Muthesius, Stefan — the concept's historians in the UK register: the doctrine, the daylight/density logic, and the consensus's end (1994).
• Walter Gropius (not paged — see log) — the arithmetical warrant: height, light and greenery; The New Architecture and the Bauhaus (1935) as the concept's English-language vehicle.
• Ludwig Hilberseimer (not paged — see log) — the layout's first formulator.
• Le Corbusier (via le-corbusier) — the Unité as the slab-block model whose English simplification became the maisonette slab.

Related Concepts

• mixed-development — the successor formula: the point-block-and-cottage pattern that displaced the row.
• public-housing — the system that built Zeilenbau at scale; the concept as planning science's housing application.
• neighbourhood-unit — the parallel planning unit: the school-focused subdivision into which Zeilenbau estates were fitted.
• towers-in-the-park — the layout's later degeneration into the vilified type ("Corbusierian Towers in a Park," p. 310).
• homogeneous-space — the spatial ideal the regular row embodies: universal orientation, equal light for all.
• eyes-on-the-street — the Jacobs counter-doctrine: the street the Zeilenbau eliminated as the city's basic institution.

Source Support

Sources in the wiki that discuss this concept:

• Tower Block (Glendinning & Muthesius 1994) — the concept's founding source: the doctrine and Gropius arithmetic (ch. 6, pp. 39–41); the UK canon (Kensal House, Spa Green, Hallfield, Churchill Gardens, pp. 43–46); the point/slab split ("an end of the Zeilenbau consensus," p. 56); the Alton West maisonette slab; and the Scottish zenith at Ardler (fig. 25.23).
• The Death and Life of Great American Cities (Jacobs 1961) — the counter-doctrine: the Radiant City's parallel rows as "nothing but lies," the coverage arithmetic that standardizes the type, and the border-vacuum reading of its open grounds (1961, in this wiki's account).
• Towers in the Park (Keil 2015) — the layout's political afterlife as the public project's density sign (2015).

Open Questions

• The Zeilenbau claim was equality of provision ("every room… received a good measure of daylight," p. 36): does its fall in the 1950s mark a shift from equality to variety as the governing value of housing design — and does that shift belong to the concept's own history or to aesthetics?
• Gropius's arithmetic (height buys light and greenery) and Unwin's diminishing returns are presented as exact opposites. Which was actually true at the densities built — and is the wiki's towers-in-the-park page the umpire?
• Ardler as "the zenith of Zeilenbau" is a retrospective judgement by designers who had already repudiated the type. Can a typology's 'zenith' be dated after its fashion's death?
• What is the Zeilenbau interior? The concept is defined in plan; the wiki's interior registers (inwardness, privacy) have not yet met the double-aspect flat.
