Vernacular architecture becomes important to the context of architecture in Asia because Asia consists of many different cultures and each of it different in each territory. Each region has a specific architecture derived from tradition, the local human adaptation of nature that gave rise to a variety of ways to cope with climate for building comfort.

The word vernacular comes from Latin vernakulus, which means domestic, indigenous, native; of Verna which means slave or a home-made indigenous natives. In principle refers to the type of vernacular architecture in which the original architecture with a specific time or place.

Contrary to the architecture designed by the architect, building on the knowledge of vernacular architecture in the channel through local traditions and usually based on trial and error passed down from generation to generation from the calculating of the physics building and its geometry.

Sometimes people get confused between vernacular architecture with traditional architecture, because between the two concepts are indeed there is a relationship. Vernacular architecture can also be taken from a culturally acceptable solution, but if only through repetition alone the buffer into a traditional architecture.

London Modern Architecture – Lloyd’s Building (1986)
Richard Rogers’ Lloyd’s building is a breath of fresh air in a city full of concrete commercial office blocks. The daring design places the stairs, elevators, power cables, air ducts and water pipes on the exterior, creating a clean uncluttered working space inside the tower. The services, things that other buildings try to conceal, thus proudly ornament the outside of the Lloyd’s building, creating its unique look.
The Lloyd’s building is located at 1 Lime Street and although not regularly open to the public the office does open each year as part of London Open House, when it’s free to visit.

London Modern Architecture – London Eye (1999)
Similarly to the Eiffel Tower, in Paris, the London Eye was originally intended only to be a temporary construction. However, due to its immense popularity, much like the Eiffel Tower, the wheel has become a permanent landmark, an instantly recognizable symbol of the city.
The Eye is located on the south bank of the River Thames opposite the houses of parliament. It is currently the most visited paid tourist attraction in country and the 30-minute ride will cost £17.50.

London Modern Architecture – 30 St Mary Axe: The Gherkin (2004)
30 St Mary Axe, affectionately known as The Gherkin (the British word for a pickle) due to its shape, is a welcome addition to the city skyline. This visually striking postmodern tower is an extremely good example of how modern architecture can enhance its local environment. The building is appreciated by both the public and professionals alike and won its architect, Sir Norman Foster, Britain’s most prestigious architectural award, the RIBA Stirling Prize.
Located, unsurprisingly, at 30 St Mary Axe, The Gherkin is only open to the public once a year as part of London Open House.

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.

As the population of Singapore is drawn from many ethnic origins, and the island has been ruled by a succession of foreign powers, the country has struggled to find its identity since gaining independence in 1965. First the city’s banks and then the government have actively aimed to develop high-quality landmark buildings with the aim of not only defining a sense of national identity, but also to boosting business and tourism. For this reason the city is full of high quality architecture.

Singapore’s Modern Architecture: Skyscrapers
In the late seventies and eighties Singapore’s businesses and hotels drew attention to themselves by constructing high-quality skyscrapers. The city became synonymous with the high-rise as buildings by some of the world’s leading architects, including Pritzker Prize winners, I.M. Pei and Kenzo Tange, rose in the city. In 1986 Singapore was the focus of the world’s attention, as the 280-meter Overseas Union Bank Centre became the tallest building outside of North America. This building would start a trend as Asian cities constructed higher and higher buildings.

First Kuala Lumpur (Petronas Towers), then Taipei (Taipei 101) and most recently Dubai (Burj Dubai) have all constructed visually interesting “world’s tallest”, skyscrapers that have focused the world’s attention on the host city. However, Singapore’s could not follow this route due to a height restriction imposed by the downtown’s proximity to the airport.

Singapore’s Modern Architecture: Municipal Buildings
Denied the chance to increase it’s exposure through the construction of the “world’s tallest building”, Singapore has tried to find other ways to distinguish itself and increase people’s awareness of the city through its architecture. City officials knew this could be achieved by creating an iconic landmark building, an Eiffel Tower or a Sydney Opera House, which would become synonymous with the city’s prosperity.

Since the beginning of the millennium three extremely high quality municipal buildings designed by internationally famous architects have been constructed in the city. First Michael Wilford and DP Architects’ Esplanade Theatre in 2002, followed by T.R. Hamzah & Yeang’s National Library of Singapore in 2005, and most recently Stirling Prize winner Norman Foster’s Supreme Law Court of Singapore in 2006. All three are examples of excellent modern architecture that Singapore can be proud of.

These buildings, and the recently completed Singapore Flyer, (which like the London Eye has become a major attraction) have drawn business and tourists to the city, however, although each building is a striking and successful addition to the city none has become the iconic symbol of Singapore.

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.
