Wood is the oldest material know to man. Alongside the spread of other materials, wood remaining characteristics of some areas- owing to its availability, easy of working and insulating properties.
in Finland two-thirds of the land areaare coverd by forests. timber has traditionally defined the image of the country, in both nature and the built enviroment. Over the past forty years, the use of wood has considerabily decreased in building as a estructural and cladding material.
Now new opportunities for structural use and surfaced treatment are restoring wood to the prominent and visible role that it use to have in the rural and urban context.

There are some examples about the uses of concrete in architecture, and there www.auburn.edu/.../ bsc314/timeline/timeline.htm you can see a historical timeline of concrete

THE KURSAAL CULTURE CENTER

Rafael Moneo’s glass cubes in San Sebastian.
Few buildings illustrate the development of international architecture during the 1990's in such a thought-provoking way as the Kursaal culture center complex in the Basque town of San Sebastian. The architecture was determined by a closed design competition in March 1990 with the Spanish architect, Rafael Moneo (b.1937) as the winner, and the scheme was completed in August 1999. In addition to spanning the period of the 1990's, Kursaal also represents the minimalistic excesses of the decade mixed with an understandable fear of being locked into a stereotyped form idiom.Originally, Kursaal was the name of a gambling casino that functioned during Spain’s Belle Epoque period from 1921-24, until a ban forced its closing, which was followed by sixty years of unsettled conditions until it was finally torn down. In 1985, the municipality acquired the attractive casino property, which made it possible to supplement Spain’s most exclusive resort town with a combined congress and concert hall.

GLASS

Glass emerged in the origins of civilization, in Egypt and Mesopotamia; however, the use of glass in architecture had to wait a long time. Windows were unknown in these two states and also in Greece and Rome. Important buildings such as the Parthenon in Athens or the Cemetery in Rome had to illuminate their interiors with an opening in the roof, which meant that not just sun, but also rain would go in. The first windows were closed with wooden panels or with blinds or shutters, which completely darkened them. Even a relatively short time ago, traditional architecture in Japan only used fixed or moving partitions, called fusuma, closed with karakami paper. For centuries, in many countries, the common solution to closing windows without losing all of the light was to use waxed paper or cloth and parchments.
Towards the end of the Roman Empire, the most important buildings put small pieces of glass which could be joined by lead canes on the windows. The Late Middle Ages did not excel in technical progress and the buildings only used small openings for lighting purposes.
However, starting in 1000 A.D., Europe experienced an enormous social advancement with the reappearance of the cities. Great buildings like cathedrals surpassed ancient construction techniques, increasing their height - in search of greatness – without increasing mass, which allowed them to increase the size of windows. In some countries like France, stained-glass windows reached their peak in the 12th century in the cathedral of Chartres.

STONES

Is materials used to the monumental construction. It´s has some advantages like durability, adaptability to sculptural treatment, moreover it can be used in modest structures in its natural state. But also it has some difficult specificly to quarry, transport and cut. there is many types of stones, the simplest and cheapest stone is the rubble. Other used to the monumental construction is ashlar masonry. The entablatures is used in ancient Greek temple, is the upper sections of a classical order that rest on the capital of a column.
The best stone is wich support more and resist the deformation caused for the wheight, and the angle.
