When Olbrich settled in Darmstadt—just before Mackintosh’s room was shown at the Sezession—he also rejected almost completely in the work he carried out at the Grand Duke’s Art Colony the still slightly Art Nouveau leanings—in any case already closer to the English Townsend than to Horta or Van de Velde—of his newly completed Sezession Building (see Chapter [20]). Only his Pavilion of the Plastic Arts of 1901 at Darmstadt retained curved elements, and those were structural rather than merely decorative. The general rectangularity and the broad horizontal windows of the Ernst Ludwig Haus, a block of artists’ studios also completed by Olbrich in 1901, suggest comparison with Mackintosh’s Glasgow School of Art. Whether or not, in fact, Olbrich knew Mackintosh’s building—he may well have seen drawings if not photographs of it—his approach here was certainly very similar.

Mackintosh had a good many further opportunities as a decorator, both at home and abroad, but only too few commissions to design whole buildings. However, his two houses near Glasgow, Windy Hill at Kilmacolm of 1899-1901 and Hill House at Helensburgh of 1902-3, are both very notable. Externally they have a certain generic similarity to Voysey’s, with their moderate pitched roofs of dark slate, roughcast walls, and plain stone trim. His prototypes are not English but Scottish, however—the simple seventeenth-century houses of the minor lairds. As one would expect from his interiors, moreover, the façades of Mackintosh’s houses are much more carefully and abstractly composed than Voysey’s; they even include some simple geometrical features that are not at all reminiscent of the past in their design. Like Voysey’s houses, Mackintosh’s show no real novelties in planning, although the disposition of the rooms is always straightforward and commodious. The interiors are very original and rather less forced than those he was producing for exhibitions on the Continent.

Mackintosh built very little after 1903 except the Scotland Street School of 1904 in Glasgow, the north wing of the Glasgow Art School in 1907-8, and the finest of the various tea-rooms that he remodelled for Miss Cranston. This was the Willow Tea Room in Sauchiehall Street of 1904, for which he remade the façade as well as reorganizing the interior. Internally this tea-room was arranged on several interrelated levels subdivided by ingenious screenwork; the exterior was a flat surface of white stucco cut by broad horizontal openings, one to a storey. The Scotland Street School is equally straightforward in design, the rather plain façade with its ranges of horizontal windows being flanked by rounded stair-towers articulated into continuous stone grids by mullions and transoms, like the bay windows of Voysey’s Broadleys but much taller.

The north wing of the Glasgow Art School is more remarkable, quite worthy of the original front but much more stylized (Plate [135A]). Where the front is strongly horizontal the new end façade, like that on the south, is markedly vertical, in part because of the way the ground falls off. But the tall oriels, glazed at the outer plane of the stonework, are striking features, and the whole composition is tense and dramatic. The library inside is a tour de force of spatial subdivision somewhat like the Willow Tea Room. Most notable is the way the rectangular stick-work makes manifest the complex articulation of the total volume. This sort of handling of interior space was unique up to this time as a product of conscious design, although already present inside Paxton’s Crystal Palace in the mid nineteenth century. Certainly there is no evidence here of a decline in Mackintosh’s creative powers; indeed, quite the contrary. Yet this library proved to be his swan song; for want of further commissions Mackintosh’s career all but closed at much the same time that the Art Nouveau was coming to an end on the Continent. Not since Ledoux perhaps had so great a talent been thus thwarted by circumstances, although just what the thwarting circumstances were, other than Mackintosh’s own temperament, is not so evident as in the case of the revolutionary French architect.

The Art Nouveau, so extensively propagated by exhibitions, is often thought to have terminated with an exhibition, that held at Turin in 1902. This is more than a slight exaggeration, as various already mentioned buildings executed as late as 1911 will have made evident. Yet after the early years of the century the decline of the Art Nouveau was almost universal except in provincial places and in outlying countries such as those of Latin America and eastern Europe. At Turin the Belgian section had characteristic Art Nouveau interiors by Horta. Mackintosh, wholly detached by now from the Art Nouveau, contributed a Rose Boudoir, typically light in colour and delicate in line with the predominant verticals and horizontals relieved by little abstract knots, so to say, of curvilinear decoration. Raimondo D’Aronco (1857-1932), the Italian architect responsible for the principal pavilions, wavered between a rather plastic, somewhat Neo-Baroque, version of the Art Nouveau, not unrelated to the seventeenth-century work of the great local architect Guarino Guarini, and a crisper mode much influenced by Mackintosh and the Viennese.

D’Aronco’s finest building, however, was not at Turin but the Pavilion of Fine Arts that he designed for the Udine Exhibition the next year. Moving sharply away from the turgidity of much of his work at the earlier exhibition, he produced for Udine a façade that was unified in design, frankly impermanent in its materials, and at once festive in spirit and dignified in tone. This was a most distinguished piece of exhibition architecture in a period when leading designers gave a great part of their attention to such rather ephemeral things—largely, doubtless, because so few opportunities to build permanent structures came their way. In Istanbul, D’Aronco built a small mosque in 1903, prominently located by the Galata Bridge, and also several blocks of flats that signally fail to maintain the promise of his Italian exhibition buildings. The very awkwardly sited mosque, raised on top of an existing structure, is as Viennese in character as the Udine pavilion.

Other Italian architects, however, remained faithful for a few years to the stile floreale, their version of the Art Nouveau. In Milan the Casa Castiglione, a palazzo or mansion-like block of flats at 47 Corso Venezia built by Giuseppe Sommaruga (1867-1917) in 1903, is a very large and ponderous example. The detail is extremely bold, inside and out, the materials rich, and a very large part of the interior is given up to a monumental stair-hall of almost Piranesian spatial complexity. A Milanese hotel at 15 Corso Vittorio Emmanuele of 1904-5 by A. Cattaneo and G. Santamaria is of a comparable extravagance. Finer perhaps, certainly simpler, is the Casa Tosi of 1910 at 28 Via Senato in Milan by Alfredo Campanini (1873-1926).[[388]]

To judge from the rather stile floreale character of some work of this period in Latin America, Italians as well as Iberians may well have carried the Art Nouveau there. In Cuba and Brazil, especially, memories of Colonial exuberance encouraged a profusion of carved or moulded ornament beyond even the excesses of the French around 1900. The most prominent example, but not the most characteristic, is the Palacio de Bellas Artes in Mexico City begun for President Diaz by Adamo Boari after 1903 and completed in 1933 by Federico Mariscal; this is ‘Beaux-Arts’—not inappropriately, perhaps—in all except its detailing; in the latest portions this reflects the Paris of the Exposition des Arts Décoratifs of 1925 rather than the Art Nouveau Paris of 1900.

In Spain itself the international current of the Art Nouveau was not very influential outside Barcelona. Gaudí, whose earlier work of the seventies and eighties has already been described (see Chapter [11]), continued to be as much apart from the contemporary Spanish architectural scene as he was from the international Art Nouveau. His finest late works, moreover, all but post-date the demise of the Art Nouveau in the major European capitals. Nor is there any such close, if ambivalent, linkage between Gaudí’s career and the general rise and fall of the mode as in the case of Mackintosh. One can only say that his personal style is more closely related to the Art Nouveau than to the new stage of modern architecture that was already succeeding it by the time he produced his final masterpieces. The premonitory character of his early ironwork has been discussed and illustrated already (Plate [96B]).

Gaudí’s work on the church of the Sagrada Familia[[389]] in Barcelona went on more or less continuously from 1884 to 1914 and began again in 1919 after the First World War. The most conspicuous portion that has so far been executed, one of the transept façades, was designed and largely built in the nineties. Dominating Barcelona with its four extraordinary towers—not finally completed until after Gaudí’s death in 1926—this façade, begun in 1891, breaks quite sharply with the Neo-Gothic of Villar’s crypt and his own chevet. The portals with their steep gables have a generically Gothic ordonnance; but the extraordinary profusion of sculpture, mostly executed after 1903, gives a highly novel flavour. While conventional enough as regards the figures, this is otherwise either naturalistically floral or else meltingly abstract. It resembles the Art Nouveau in many minor details, but is generally bolder in scale, more fully three-dimensional, and, in places, somewhat nightmarish.
