The glass and metal appeal of modern homes and commercial buildings came into popularity in the years following World War II. Originally, modern architecture was more a social movement rooted in political rhetoric; form and function were more statement than artistry. Amid the ruins of war torn Europe in the 1920s and 1930s, there came into being the Bauhaus, a school for artist that included architectural pursuits. The “school motto” was Start from Zero.

Such notables as Mies Van der Rohe and Walter Gropius came to represent the modern architectural movement. The politics behind the movement were a complex weave of anti-war sentiments, socialism and machine age glorification.

These sentiments were embodied in basic materials such as concrete and stone, glass and metal. The function of space was to function as space, providing only that which man needed. The styling of traditional architecture, from gabled roofs to corbels to stained glass windows were eschewed. Windows were designed to allow in light and heat. Roofs were designed to protect the inhabitants from the elements. Any ornamentation was superfluous. Basic spaces to meet basic needs.

After World War II, the basic rectangular form that functioned as modern architecture became more appealing to the populations of the now super industrialized West. All things modern were considered desirable, and modern architecture as seen today came into its own.

Though still lean in design, current forms of modern architecture have become more stylized, particularly in residential design. Roofs with one-sided slopes to encourage passive heat flow, rectangular structures with interior curved walls to encourage air distribution throughout, and honest materials of reclaimed wood, concrete and stone all find their way into modern architecture.

The form of the structure itself becomes the ornamentation of the style. Though originally boxy and cubicle in nature, modern design now follows the land’s contours while still retaining basic geometric structure. The results are decidedly non-traditional, yet are decidedly different from the intentions of the founders of Bauhaus.

The idea behind their rally cry of Start from Zero was one of a deconstructionist ideal. The founders wanted to take apart all that had come before and reconstruct architecture, and indeed societies, to suit a leaner, more streamlined way of living.

The simplification of living spaces by eliminating ornamentation and making no effort to hide the origins of materials and craftsmanship was, and remains, the primary characteristic of modern architecture. But that modern architecture has become a stylish and exclusive design for those who can afford such homes would surely disturb the socialist thinking of Walter Gropius and the followers of Bauhaus design.

Canal rings houses
The old centre was formed by rings of canals with unique mostly 17th century residences of wealthy merchants, financiers, craftsmen, doctors, lawyers, politicians and artists. Because of lack of space, these houses were mostly narrow, not more than 30ft wide (9 meters). They are are characterized by big narrow windows, decorative gable tops, very narrow stairs inside and pulley outside to transport larger objects to upper floors. Very often the residences served also as businesses. Merchant’s houses had their storage in attics and cellars. Sometimes the lift was installed in the middle of the house plan, to transport the goods between floors. The office of the merchant was usually on the ground floor. Like in Venice the canals were the main way of transporting the goods.

Classicism
At the end of the 18th century classicism produced in Amsterdam several monumental buildings, with probably the most interesting called Felix Meritis by Jacob Otten.

Historicism and Art Deco
The development of Amsterdam into the modern city at the end of the 19th century resulted in construction of the several landmark city buildings as Central Station, Central Post Office (today rebuilt into a shopping mall Magna Plaza), Rijksmuseum (State Museum), Stedelijk Museum (Municipal Museum), Stadsschouwburg (City Theater), Concertgebouw (City Philharmonic)and St. Nicolaaskerk. The foremost architect of this was P.J.H.Cuypers. Architecture of these building was searching for the historical inspiration, using elements of gothic and renaissance.
Art Deco popular at the turn of the 19th century in the whole Europe, left several interesting buildings in Amsterdam with the American Hotel as its foremost example with wonderful interior of the café and lunch room.

Hendrik Petrus Berlage
At the beginning of the 20th century an important milestone has been a vast plan of the expansion of Amsterdam into the dimension of the European metropolis, called Plan Zuid (Plan South – 1915) by an architect H.P.Berlage, often regarded as the Father of the Modern Dutch architecture.
Located just near the Dam square the Stock Exchange building (1903, now called Beurs van Berlage and used as exhibition and concert hall) also by the architect Berlage precedes the Amsterdam School style and is often regarded as influential to the whole Dutch architecture of the first half of the 20th.

The Amsterdam School style
At the beginning of the 20th century, the new housing law in the Netherlands started the boom of the low cost housing for the working class. Most of these quarters were built in a new distinctive style called the Amsterdam School (Dutch: Amsterdamse School). It was first applied by Michel de Kerk is a housing block called Het Schip (The Ship) – today regarded as a monument, with the museum of this architecture style in a former post office.

Functionalism (1920-1970) and after
As in many other European countries Dutch architecture after 1920 has been influenced by the ideas of the French architect Le Corbusier. New technologies – use of concrete, prefabrication, standardization as well as strongly emphasized function of the building are characteristic for architecture of this movement. The most imprtant architects were Gerrit Rietveld, Jacobus Oud, Johannes Duiker, Cornelis van Eesteren, Michiel Brinkman and Leendert van der Vlugt. The finest examples of functionalism were, still influenced by the Amsterdam School style housing district Betondorp (1921-1928) and Van Gogh Museum, by Gerrit Rietveld (1963-1973).
Later years (before 1990) brought several different streams in Dutch architecture. The most interesting architects of the 1960-1990 in Amsterdam were Aldo van Eyck, Herman Hertzberger. Still, it may seem that functionalism has been heavily influencing new projects.

When I was touring northern Italy and Spain I was struck by the timeless beauty of wrought-ironworks, fashioned out of the architecture of the buildings and into the garden trellises. It was not so much the ornate details that I found so interesting as I found the strength and durability of the material to be: it tested time, only growing more attractive. Later, back in the U.S.A. and practicing my profession as a Landscape Architect I found that wrought-iron was not often affordable except in only the most selective of projects (i.e. those with very, fat budgets).
I did design my share of wooden and hollow-tube trellises over the years but I was always looking for a material that would capture the essence of wrought-iron and at an affordable price. That is when I began experimenting with REBAR (reinforced iron for concrete building footings).

Rebar comes in a variety of diameters and surface patterns, usually in 20 foot lengths. It is the ‘poor cousin’ of construction-metals exclusively finding its’ way into concrete pours to reinforce the structural value of footings, walls and flat surfaces. I have not seen it utilized for much else.

There are quite a few good reasons why rebar works well as a trellis building material. Personally, I like the way it looks, it reminds me of Sahuaro Ribs and Ocotillo sticks used in the Southwest. It also takes on the look of knotty pine poles as well. Part of its attraction is that the knobby surface catches the light in a play of shadows throughout the day (and also in the nightime with directed, accent lighting).

Rebar does not have to be treated or painted; it looks best in its natural state of surface rust. It can, however, stain tile or fabric beneath it. In a rainy climate it is a good idea to spray a mat-sealer over those areas that may drip. Most landscape surfaces, however, are durable enough to handle these occasional drips. On one occasion we had the rebar elements, powder-coated with bright colors to go with the festive character of the project (powder coating is baked-on paint, like on a automobile). I do not recommend this treatment because of its expense but it does have its uses.

Although rebar does not sculpt well as wrought iron will, it can be bent within certain limits. In fact, the bending of the rebar can be best taken care of at the rebar yard itself, (look under rebar suppliers in the yellow pages). They receive

specifications from building contractors for all sorts or shapes and configurations to accommodate their building footings etc. They usually raise an eyebrow to such requests eg. rebar stock bent for a trellis, but more often than not they get into the spirit of the project and appreciate the change of pace.

I once designed and built a rebar trellis that we named “Double-Helix”, a vine trellis; the curve linear shapes of the trellis’s roof-line created a shadow of a double helix on the ground. You also saw the double helix form when walking by the trellis. Naturally, you can build a rebar trellis out of straight pieces of rod as well and eliminate the bending. A really nice look is to use different diameter rebar sticks and place them alongside one another in a descending pattern. They can also be cut to different lengths and also be placed in a descending pattern. It is really up to your imagination or that of your designer and landscape contractor.

Some of the ’straight-rod’ rebar trellises that we have designed and built were topped with another interesting material i.e. sheets of reinforced, metal used to reinforce concrete driveways. These sheets generally come in 7 foot widths and vary in lengths, of about 10 feet. Their box pattern is usually in 4 inch squares; this allows for plenty of air flow and a chance for the vines to trail throughout the webbing.

Lastly, anchoring a rebar trellis to the ground is quite simple. Basically all you need to do is to dig a 2 foot or better deep hole, set the rebar leg into it and pour your concrete mixture around it. You can also integrate all or part of the trellis’s legs into a patio wall, if the overall architectural design of the house and garden will benefit from this application. Naturally, have your construction details reviewed by your licensed landscape contractor.

Italy’s Romanesque architecture (12th cent.) reveals the first use of the groined vault with projecting ribs. It is also typified by the development of a type of basilica having side galleries. The style was especially pronounced in Lombardy and is superbly exemplified in Sant’ Ambrogio, Milan. There are two regional forms of Italian Romanesque—Tuscan (including Florentine) and southern. The cathedral of Pisa (1063-1118), with its campanile (the “leaning tower” ), admirably displays the Tuscan characteristics, chief of which is the decorative use of tier upon tier of columns. Tuscan architects of the period also made a specialty of using variegated marbles and followed the antique style in this rather closely. The Romanesque of the south, as in the cathedral of Monreale, is characterized by its rich mosaics and delicate carvings, which show Byzantine, Saracenic, and Norman influences.

Gothic Influences

Gothic architecture was not greatly developed in Italy; a notable exception is the cathedral of Milan, built in part by foreign architects. The Church of St. Francis in Assisi (begun 1228) and the cathedral at Siena (begun 1269), among others, also have Gothic elements—the ribbed vault and the pointed arch (see Gothic architecture and art ). However, the Italians largely adhered to the native tradition of building in terms of simple basilican proportions with massive walls, a practice that was carried into the Renaissance.

The Renaissance

In the 15th cent. a conscious revival of classical antiquity began (see Renaissance art and architecture ). Brunelleschi emulated the ancient Romans in his masterly construction (1420-34) of the dome of the Florentine cathedral, and Michelozzo used antique elements in the courtyard of the Medici Palace, Florence (begun 1444). Alberti borrowed freely from a Roman triumphal arch in his design (1450s) for the exterior of the Tempio Malatestiano in Rimini. Bramante, Antonio da Sangallo, Peruzzi, and Raphael made Rome the center of spectacular architectural developments in the first half of the 16th cent., when St. Peter’s was the most important project under way. Vignola did significant work in Rome in the latter part of the 16th cent., while in N Italy the formal classicism of Palladio was a potent factor in the spreading of Renaissance architecture throughout Europe. The monumental work of Michelangelo reflected elements of mannerism and his influence extended into the baroque period.

The Baroque

The beginning of the 17th cent. ushered in the drama of the baroque era with Maderno’s nave and facade for St. Peter’s, to which a magnificent colonnaded plaza was added, designed by Bernini, the foremost genius of the period. Other outstanding architects of the century included Borromini, Cortona, and Rainaldi. After their deaths, Carlo Fontana became the most influential architect in Italy, transmitting the ideas of the great baroque masters to many of the most important architects of Europe. Italy, however, no longer possessed the undisputed leadership in European architecture, although in the 18th cent. Piedmont in N Italy produced remarkable designers, such as Guarini, Juvarra, and Vittone.

The Modern Era

Nineteenth-century Italian architecture, such as Giuseppe Sacconi’s Victor Emmanuel monument, shows a decline in quality and increased pomposity. In the 20th cent. Italy has followed the trends of modern architecture ; its outstanding practitioners include Pier Luigi Nervi , Giuseppe Terragni, Gio Ponti, and Renzo Piano.

Although architecture is not widely recognised as an “important” and “popular” profession it is in fact one of the most influential and widely recognised jobs throughout history. Almost everything we know about ancient civilisation is based upon what we have found in and about it’s architecture and there are countless political and cultural symbols known primarily for their structural achievements such as the Pyramids of Egypt and the Roman Coliseum. Even modern cities and locations are both visited and known by architectural landmarks such as the Opera House of Sydney and the Empire State building of New York.

The history of architecture is also extremely interesting, as human technology and scientific and mathematical understanding increases, so to did our ability to build wonderful buildings. Architecture was born out of a combination of needs, such as shelter, security and worship and means, mainly the local building materials and physical ability. Early architecture was mainly vernacular architecture, a special type of architecture which is based around local needs and means. As it evolved the classic civilisations were born and great time and effort put into crafting areas of religious or political significance and even back in these times architecture was more than just a visual product. The roman Coliseum was designed so that all of the thousands of crowd members could see and hear the action at the centre and the way it amplifies sound was no accident.

As time passed architecture developed more and more with medieval structures like the castle and fort proving architecture had a place on the battle field as w ell as he city floor. During this period architects, especially in Europe, began to form guilds (as many craftsman did then). These guilds were design to help architects work together and achieve more monumental things, a practice that is still in society today in the form of architect partnerships.

In the renaissance architecture became a very personal affair and moved quickly away from war and religion. Many famous architects are from this period as this marked the start of buildings recognising their architects with individuals such as Palladio and Brunelleschi going down in history.

Today architecture is everywhere, almost any public building is professional designed and many compete for recognition inside their respective cities. There is massive emphasis on certain elements such as energy efficiency, environmental blending and the use of environmentally friendly construction materials. Design is also becoming increasingly advanced with superstructures like the Burj Al Arab 7 star hotel.
