What is the biggest change between modern architecture and ancient architecture? Why are there these changes?

The first is site selection. Ancient buildings will pay more attention to feng shui, with mountains and rivers behind them. Because the ancient people were underdeveloped in science and technology, it was difficult to take artificial measures to avoid disasters, so they needed natural protection more. The site selection criteria of modern buildings are broader.

Secondly, materials, natural materials are selected for ancient buildings, such as wood, stone, clay and so on. In addition to natural materials, modern buildings have more artificial materials, such as bricks, concrete, steel, glass and so on.

Thirdly, the structural types are limited by materials, and most of the ancient buildings are wooden structures (east), stone structures (west) and earth buildings. Modern building structures are mostly brick-concrete structures, reinforced concrete structures and steel structures. , more durable and firm, avoiding the harm of fire.

There is also the modeling of buildings. The modeling of ancient buildings is limited by regions, and a certain region or period is mostly a single architectural form. With the social progress and cultural exchange, modern architecture has broken through the geographical restrictions, and often a variety of architectural forms will appear in a region.

The reason is that technological progress determines the ancient and modern changes of architecture.
