Architecture of Saudi Arabia
Architecture Of Saudi Arabia was not different in the pre-oil era during the early 1930s from what it was across the past centuries. Construction and building activities followed a simple and modest style back then, as there was a lack of specialized architects in the modern sense. Instead, native communities would erect their own structures manually through the efforts of builders using basic means and local materials in what came to be known as “traditional architecture.” Every region in Saudi Arabia was famous for its own brand of architecture that expressed its artistic taste. Building materials used at that time were sourced from the local environment, such as clay, rock, palm fronds, and wood. Similarly, the architectural styles passed on from generation to generation reflected each region's climatic and environmental conditions.
The impact of climate
The area for the modern day of Saudi Arabia can be divided by four distinct regions and due to the unique geographical location of Saudi Arabia, the climate varies from region to region, so the style of architecture in each region is different.Architecture in the Western Region
In the western region, it is a hot-humid climate and located in coastal plain along the Red Sea. The structural skeleton of the house is made up of large coral columns and with wood floors and roofs. In ground floor is general sitting room and the more private sitting room is located in the first floor. The sleeping room is generally located on the upper floor and in summer are sleep on the roof so that there is better ventilation in the sea breeze and natural winds.Architecture in the Central and Northern Region
In the central and northern, it is a desert climate, therefore, the weather is hot and dry and has a great temperature difference between day and night. The typical houses in the Najd region are usually two stories high and built around an open central courtyard. The shape of the courtyard is usually geometric like a rectangle or a square and it works as lungs of the houses to regulate the microclimate and provide a private space for the family to maintain the private life. The houses are built on either side of the narrow streets, providing a shady place for pedestrians. The roof level of the house is used for sleeping in summer. The main material to build this kind of house is sun-dried mud bricks and mud. The mud is worked as plastering material used to smear interior and exterior walls, it is very suitable for the sandy weather the reason why is because the colour is unaffected by the weather. The exterior walls are thick which are about 80–100 cm, thus, it can effectively isolate high temperate and create comfort level to the residents.Architecture in the Eastern Region
In the eastern region, it is a hot humid region along the Persian Gulf. It has the extreme weather which means in summer months it is hot and dry and has a high rate of humidity temperature day and night.The traditional house in this region has a courtyard style and the arcade balcony around the house. Due to the harsh climate, the height of the typical house in the eastern region is one to three stories high and the building is very compact, resulting in a narrow passages between houses. The wall of this type of houses is thicker than other types which have better heat resistant and has the effect of insulating. The way to create natural ventilation by installation wind catchers.
Asir region
The Asir region, it is a high mountains province to the southwest side and it has the Mediterranean climates which characteristics are dry summers and rainy winter.The Asir houses are commonly built on the high mountains province due to its geographical location. Climatic conditions promoted the emergence of architectural society. The building normally makes up by one ground and two upper floors which can provide shelter for man and tamed animals. The main sitting room is on the first floor, while the top floor is the kitchen and bedroom, at the same time the open terrace is also added to the upper floor for wash purpose. In each house there is at least one room used for male reception, which separates from female quarters and family living rooms. The staircase occupies the middle of the house and material of the staircase is mud and use wooden beams to sustained.
Evolution of Architecture in the Post-Oil Era
The period between the discovery of oil in 1352 AH/1933 AD and the peak of the oil boom in 1393 AH/1973 AD served as a historic turning point in Saudi Arabia's architectural identity, transforming it from a resource-scarce country dependent on limited agriculture and herding livestock to a manufacturing nation.Economic growth accelerated once crude oil production began on a commercial basis after the end of World War 2. One of the biggest urban impacts of this economic transformation was the emergence of modern cities, which coincided with the first waves of urban migration from within and beyond Saudi Arabia to major metropolises and oil manufacturing hubs in Dhahran, Khobar, and Dammam in search of better employment and business opportunities. The exponential rise in population called for the launch of the first urban planning process in the Kingdom, which took place with the modernization of Khobar's master plan in 1366 AH/1947 AD, incorporating a completely modern urban style based on road networks and transportation systems. The plan was also based on implementing global urban standards, which served as the first model for town planning in the Kingdom and were a critical factor in defining modern architecture in these cities.
These standards were adopted across Khobar and included setting road dimensions, land use planning, and determining the size of residential colonies and building heights. The introduction of automation into construction played a big role in optimizing the entire industry after it had previously depended on manual work. The establishment of power plants enabled the introduction of machinery that could produce building materials locally, such as concrete and cement bricks. Its spread also helped usher in a modern architectural identity that completely replaced traditional architecture.
Vernacular architecture
The characteristic of vernacular architecture is using the local resources, needs and material to build the house, therefore this kind of house reflect the local traditions, history, culture, environment and climate. Due to the climatic zone, the vernacular architecture will use different bioclimatic features and the benefit to using their features are having air ventilation, thermal comfort and suitable lighting in the building.In the past, aborigines use limestone as the main material to build their house because limestone can be collected at local quarries in Najd. But in recent decades unfired mud-brick and wooden beams were the main building material used in Najd. The craftsman will apply the mud plaster paste to the wall with a wooden scraper and through wooden scraper moves across the wall to leave the parallel pattern. The bottom of the wall is made up with the four or five cut-limestone. Although unfired mud-brick has dominated Najdi architecture, the pillars of the house and mosques are usually built with stone. Because stone last longer and more resistant to corrosion than mud and wooden beams. The interior wall decoration of buildings for the wealth households is very delicate, the wall covered with geometric figures carved with plaster and flowers pressed with molds.
The decorative motifs that were used on traditional building in Arabia were based on the use of mud reliefs. But across the land of Arabia, using color to painting the house only in Asir region. In order to personalize the residential building, people are encouraged to se the rich natural color pigments and plant colors in their surrounding landscapes in their dwelling units.
