In the captions that describe the images of the 74 buildings contained in the seminal book for architects, The International Style, the two American authors — architectural historian Henry-Russell Hitchcock and architect Philip Johnson — speak about every element of the so-called modern style of architecture. With hindsight, we can rightly affirm that just one ingredient is missing from those original descriptions: space. Simply, it seems that according to those brief accounts of modern architecture dating back to 1932, space didn’t exist at all as a conceptual tool for architects. Strange but true: the now distinctive character through which interpreting modern architecture especially — space — was almost totally missing in the first book that presented modern architecture to the public.
Here, we can read a representative selection of those descriptions, where the authors speak of: ‘fine proportions’, ‘smooth surfaces and carefully studied forms’, ‘shape of the concrete supports’ (Turun Sanomat Building, Turku, Finland, 1930; architect: Alvar Aalto), ‘acoustical considerations’, ‘shape of the interior’ (Flamman Soundfilm Theatre, Stockholm, Sweden, 1929; architect: Uno Åhrén), ‘dominating roof plane over transparent screen wall’ (Dapolin Filling Station, Kessel, Germany, 1930; architect: Hans Borkowsky) ‘structural regularity’ (Van Nelle Factory, Rotterdam, Holland, 1928-30; architects: Brinkman & Van Der Vlugt), ‘rich surfaces of varnished plywood’ (Finnish Pavilion, Antwerp, Belgium, 1930; architect: Erik Bryggman) ‘red, white and blue color’, ‘asymmetrical placing of door and shop window’ (Filling Station, Cleveland, Ohio, 1931; architects: Clauss & Daub), ‘open interior planning’, ‘rear wing […] painted pale green’, ‘window arrangement’ (Single House and Double House at the Weissenhofsiedlung, Stuttgart, Germany; architects: Le Corbusier & Pierre Jeanneret), ‘simple rectilinear volume’, ‘asymmetrical composition’, cream-white ‘prevailing color’ and different colors for walls ‘to emphasize the planes’ (Stein House, Garches, France, 1928; architects: Le Corbusier & Pierre Jeanneret), a ‘weightless’ second storey on ‘round posts’, ‘severe symmetry’, ‘blue and rose windshelter’, ‘open terrace within the general volume’, ‘sliding glass wall’, ‘ramp and circular staircase’ (Savoy House, Poissy-sur-Seine, France, 1930; architects: Le Corbusier & Pierre Jeanneret), ‘combination of masonry and isolated post construction’, ‘non-supporting wall sections’ made of stucco or glass, ‘wooden fly-screen frames’, ‘wall of transparent, translucent and opaque panels’, ‘ceiling of plywood in natural color’, ‘floor of local tiles’ (DeMandrot Villa, LePradet, France, 1931; architects: Le Corbusier & Pierre Jeanneret), placing of fireplace and chimney away from the wall to avoid ‘the traditional massive effect’, ‘circular skylight’ (Annex to Churh Villa, Ville d’Avray, France, 1929; architects: Le Corbusier & Pierre Jeanneret), ‘walls […] surfaced with stone plaques’, ‘set-back’, ‘curved corner’ (Breuninger Department Store, Stuttgart, Germany, 1931; architects: Eisenlohr & Pfenning), ‘extreme regularity’, proportions ‘rather heavy’, ‘general effect […] lightened by the balcony railings’, ‘red artificial stone’ (House for Two Brothers, Brno, Czech Republic, 1931; architect: Otto Eisler) ‘large glass area […] particularly suitable in a dull, foggy climate’ (Royal Corinthian Yacht Club, Burnham-on-Crouch, England, 1931; architect: Joseph Emberton) ‘windows muntins and railings produces a subsidiary rhythm’ (Electrical House, Monza, Italy, 1930; architects: Figini & Pollini), ‘glass tiles’, ‘orange red tile of the wall surface’ (Pavilion, Brno, Czech Republic, 1928; architect Bohuslav Fuchs), ‘entirely transparent walls’, ‘glass panes as a surfacing material’, ‘projection of the roof cap’ (Bauhaus School, Dessau, Germany, 1926; architect: Walter Gropius), ‘wings […] skillfully composed’, ‘checkerboard window arrangement’, ‘ribbon windows’, ‘supports […] awkward in shape’ (Bauhaus School, Living Quarters, Administration and Classrooms, Dessau, Germany, 1926; architect: Walter Gropius), ‘brick as a wall surface’, ‘asymmetrical placing of the stair tower and vertical window’ (City Employment Office, Dessau, Germany, 1928; architect: Walter Gropius – see Image 01, below), ‘circular windows’, ‘top balcony unnecessarily heavy’ (Siedlung Torten – Cooperative Store & Apartments, Dessau, Germany, 1928; architect: Walter Gropius) …

… ‘pronounced wall capping’, ‘rough stucco’, ‘effect of surface’, ‘aluminum window frames’ (Apartment House, Zurich, Switzerland, 1929; architect: Max Ernst Haefeli), ‘common rooms’, ‘orderly composition’ (Old People’s Home, Kessel, Germany, 1931; architect: O.

At this point in the book, after the illustration of Mies van der Rohe’s Apartment House at the Weissenhof Siedlung in Stuttgart, Hitchcock and Johnson present what are unanimously considered by modern and contemporary architects, critics and historians of architecture two pivotal projects that gave architecture a fully-fledged interpretative development in the spatial sense: the German Pavilion at the Barcelona Expo of 1929, and the Tugendhat House, 1930, both designed by the great German architect Mies van der Rohe. Let’s see the key terminology that Hitchcock and Johnson have used to describe those two projects. Concerning the German Pavilion, which, in the book The International Style, is illustrated using two different photos and a drawing plan, we read: ‘aesthetic rather than functional considerations determined the plan’, ‘walls are independent planes’, ‘continuous slab roof’, ‘light metal posts’, ‘regularity in the spacing of the supports’, ‘wide variety in the placing of the wall screens to form separate rooms’, ‘rich materials’, ‘plains retain their independence’, ‘the composition is of apparently intersecting, rather than enclosing, planes’, ‘different textures’, ‘a magnificent background’. As concerns the descriptions of the Tugendhat House (Brno, Czech Republic, 1930), illustrated by way of 2 drawing plans and four different photos we read: ‘a cantilevered parapet one hundred feet long above a wall of glass’, ‘a monumental flight of steps’, ‘a slab roof across the entrance joins the garage to the house’, ‘the chimney is a strong vertical accent’, ‘an almost window-less façade’, ‘a wall of frosted glass curved around the stairwell lights the entrance hall’, ‘isolated bronze post’, ‘bronze window frames’, ‘reflecting surface of glass’, ‘pattern of travertine paving’, ‘thin roof capping’, ‘graceful railing and growing plants’, ‘a onyx spur wall separates the library […] from the drawing room, but does not interfere with the open feeling of one large room’, ‘velvet curtains […] separate the rooms more completely’, ‘glass walls’, ‘color scheme’, ‘macassar wood’, ‘chrome posts and plate glass’.

Surprisingly, just like in the proceeding descriptions, we find no mention of space. Just a surrogate, on a few occasions: the term ‘room’ (which has a different connotative or imaginative power with respect to the more neutral and abstracting character that ‘space’ has). Today, it would be almost impossible to hear some architect speaking about those two projects without using the term ‘space’ as the main, if not the unique, interpretative key. I was curious to see how the famous Swiss historian Sigfried Giedion described those two projects, in another seminal book for architects — Space, Time and Architecture (1940) — and which terminology he used: I didn’t have to read too much before encountering the term ‘space’ almost immediately in his descriptions. Here is the caption of the published image that describes the German Pavilion: ‘With unsurpassed precision, he [Mies] used pure surfaces of precious material as elements of the new space conception’. I had to wait even less — just 9 words — before the term space was introduced with regard to the description of the Tugendhat House, ‘which achieves extreme generosity in its flowing interpenetration of space’. This shouldn’t be a surprise since Giedion was one of the pioneering advocates of the space-paradigm in architecture, if not the very first historian to reach (and influence) a wide audience of architects with his spatial interpretation of both traditional and modern architecture. Concerning this aspect, the English historian of architecture Adrian Forty says that Giedion’s book — Space, Time and Architecture — ‘provided the first substantial English language account of the history of architecture as an art of space, and probably marks the point at which the term [space] became accepted in English.’
In the book The International Style, the two aforementioned projects are interspersed with another project by Mies van der Rohe, the modern champion of the space-paradigm successfully applied to built architectures: the Lange House (see Image 24, below). Again, in the caption that describes the image of that project, we find no mention of the term space: the project is here described as characterized by the ‘use of brick’, and we also read that ‘the terrace, laid out geometrically, contrasts with the grounds which are planted naturalistically.’
After this brief interlude, I continue with some other representative captions of the images of other modern buildings showcased in the book The International Style, before making some conclusive remarks. Then, we read about ‘variety of surfaces’, ‘window wall covered by blue raw silk curtain’, ‘a wall of book on palissander shelves, white plaster ceiling, and straw matting on the floor’ (Apartment Study, New York, 1930; architect: Mies van der Rohe), ‘various projections’, ‘metal and stucco spandrels’, ‘regularity of structure’ (Lovell House, Los Angeles, California, 1929; architect: Richard J. Neutra), ‘projecting balconies’, ‘screens’ (Row of Small Houses — Weissenhofsiedlung, Stuttgart, Germany, 1927; architect: J.J.P. Oud), ‘wall surface’, ‘wooden windows frames’, ‘windows as a continuous band or second storey wall screen’ (Shops – Siedlung Kiefhoek, Rotterdam, Holland, 1928-1930; architect: J.J.P. Oud), ‘subordinate rooms’, ‘rounded chimney’, ‘simple rectangular block’ (Church – Siedlung Kiefhoek, Rotterdam, Holland, 1928-1930; architect: J.J.P. Oud), ‘luxurious and feminine character’, ‘white material of various textures’ (Bedroom in the Berlin building Exposition, Berlin, Germany, 1931; architect: Lily Reich), ‘curved end […] gives distinction to the whole design’, ‘fenestration’ (Apartment House — Siedlung Siemensstadt, Berlin, Germany, 1930; architect: Hans Scharoun), ‘ribbon windows’, ‘doors arranged to the window rhythm’ (Professional Women’s Residence, Basel, Switzerland, 1928; architects: Artaria & Schmidt), ‘clear design’, ‘window detail’, ‘color is coral red’ (Waldner House, Basel, Switzerland, 1930; architects: Artaria & Schmidt) ‘common rooms’, ‘one-room apartments oriented to the south’, ‘the wall above the balcony is pale blue and that below bright red. Other walls and posts are white’, ‘excellent refinement’ (Budge Home for the Aged, Frankfort, Germany, 1929-1930; architects: Stam & Moser), ‘long thin roof slab’, ‘terrace overlooking the water’ (Bathing Beach, near Zurich, Switzerland, 1928; architects: Steger & Egender), ‘wooden houses facing south’, ‘roofs are not flat but the pitch is made slight’ (Siedlung of the Swedish cooperative Society, near Stockholm, Sweden, 1930; architect: Eskil Sundhal), ‘painted match-boarding admirably used on wood construction’, ‘pipe support’, ‘walls are pale lemon yellow; base and entrance are mahogany red’ (Biological Laboratory, Highlands, North Carolina, 1931; architects: Tucker & Howell; consultant: Oscar Stonorov), ‘brick courses’, ‘wall of glass’ (Schulz House, Westphalia, Germany, 1928; architect: Lois Welzenbacher), ‘curved corner’ (Apartment house, Innsbruck, Austria, 1930; architect: Lois Welzenbacher), ‘rounded edges blur the effect of volume’ (Electrical Laboratory, Tokyo, Japan, 1929; architect: Mamoru Yamada), ‘projecting wing’, ‘set-back sun terraces’ (Childern Clinic, Essen, Germany, 1930; architect: Essen Office of the City Architect), ‘adjustment to site’, ‘light to each row of classroom with their garden’ (Friedrich Ebert School, Frankfurt, Germany, 1931; architect: Ernst May, Frankfurt Office of the City Architect), ‘slanted roof’, ‘traditional planning on symmetrical axes’ (Exposition Building, Mannheim, Germany, 1930; architect: Mannheim Office of the City Architect), ‘vertical and curved elements’, ‘functional justification’, ‘aesthetic success’ (Electro-Physical Laboratory, Moscow, ex USSR, 1927; architect: Government Architects), ‘the line of the roof slab is unnecessarily complicated by the jog and curving corners’ (Automatic Post Office, Stuttgart, Germany, 1931; architect: Postal Administration).
Images 25-33: Examples of modern architectures showcased in the book The International Style (1932), by Henry-Russell Hitchcock and Philip Johnson (for references and credits of each Image see the paragraph below).
To sum up, these are the architectural elements, or ingredients, that define some concrete examples of modern architectures distilled through the original descriptions of H-R. Hitchcock and P. Johnson in the book The International Style: walls, roofs, floors, piers, ramps, staircases, balconies, terraces, parapets and railings, chimneys, arrangement of doors and windows, composition of ‘surfaces of volume’ to define the overall exterior aspect of buildings (façades), colours, materials, textures… No direct mention of ‘space’ is done, not even once. This must be suspicious for current days architects, critics and historians of architecture since it seems no current interpretation of architecture is possible without ‘space’. However, be careful: I’m not denying the importance of space for architecture. Overall, I think the introduction/invention of architectural space is an important modern interpretative other than practical achievement for understanding the complex phenomenon of architecture. Possibly, the invention of ‘space’ and its physical transposition from the realm of abstract ideas into the realm of built architectures is one of the greatest contributes that modern thinking has offered to architectural theory and practice so far. Yet, this is the ultimate question I ask architects: Where is space?
Were architects, until the 1930s, so blind or short-sighted not to see what seems so evident for us, modern-day architects? Evidently, the explanation (and space as well) is somewhere else, not certainly, or not directly, in the actual world of walls, roofs, ceilings, floors, doors, windows, their materials, colours and textures. But if space does not directly belong to the realm of those actual, physical elements that constitute the domain of realized architectures, is it still possible to interpret architecture as a spatial discipline, sic et simpliciter, or to say that architecture is an art (and science) of space, as it has been said by modern historians and critics and it is now widely accepted by architects? Or should we better amend and go beyond that interpretation offering a more encompassing vision concerning the complex phenomenon of architecture? Can the concept of place — a revised concept in the overarching sense that I’m proposing here — be representative of those concrete elements of architecture so that the placial hypothesis in architecture can complement the spatial hypothesis allowing architecture to reach its fully-fledged potentiality and development as the discipline of dwelling place and space? Isn’t architecture a complex and encompassing phenomenon that embraces both the placiality of physicochemical, biological (hence ecological), sociocultural processes and the spatiality of symbolic processes, which, taken together, square the circle of reality in any of its multifarious aspects and values, in the compass between the concrete and the abstract? If so, why this continuous, redundant and almost exclusive reference to the abstracting character of space to offer architecture (and related spatial disciplines like urban planning and design or even interior design) a proper ground, overlooking — if not disregarding — what is necessary (i.e. place — the environment and its processes) for any typology of space to exist?

 Henry-Russell Hitchcock and Philip Johnson, The International Style, New York: The Norton Library, 1966. Originally published in 1932 — with the following title: ‘The International Style: Architecture Since 1922’ — the book presents the emergence and development of a new style of architecture in the first decades of the past century; this new style, or ‘international style’, has characterized the beginning of the modern epoch for architecture. The book was prepared concurrently with the first architectural exhibition held at the Museum of Modern Art, New York, from February 10 to March 23, 1932. The exhibition was organized by Hitchcock and Johnson after the request of the director of the MoMA, Alfred H. Barr, in 1931. A catalogue, with the title ‘Modern Architecture: International Exhibition’, edited by Hitchcock and Johnson, with a foreword by Barr, and an intervention by Lewis Mumford, accompanied the visitors to the exhibition.
 Ibid., 183-184.
 Ibid., 187-190.
 Contrarily to what we (do not) find in the book The International Style, in the catalogue that accompanied the first architectural exhibition held at MoMA, in 1932, Philip Johnson described both projects — the German Pavilion and the Tugendhat House — relying on the ‘space’ concept as an interpretative key in more than one occasion. This curious linguistic and interpretative discrepancy between the catalogue of the exhibition — Modern Architecture: International Exhibition — and the book prepared prepared concurrently with the exhibition — The International Style: Architecture since 1922 — is something I will return on in a forthcoming article.

 The definition I gave about architecture — Architecture creates spaces and modify places for dwelling — is a way to make the placial hypothesis in architecture (concerning that which is concrete, to begin with) complementary to the spatial hypothesis (concerning that which is abstract), thereby allowing architecture to reach its fully-fledged potentiality as an encompassing phenomenon in between the concrete and the abstract, that is in-between physicochemical, biological, socio-cultural and symbolic aspects and values, which are — I argue — ‘substantiated’ by the concepts of place and space, respectively. Those aspects and values also define the structure of reality at large (in this respect, see the excerpt On the Structure of Reality, which I have taken from the book Lila, by Robert M. Pirsig); in this way, I try to unveil the primal role of architecture as an encompassing phenomenon that is intrinsic to and characteristic of reality at any level: physical, chemical, biological (physiological, psychological), ecological, social, anthropological, cultural, industrial, technological, economic, political, ethical, symbolic, etc.
