Doors

According to the Dutch architect, a door is "a place made for an occasion". It's designed,created, and utilized for privacy, security, and protection from most climates. Doors have not changed very remarkably-since they were first created and used in Egypt. The common form of doors- sliding doors and swing doors- were also used in Greece and Rome. The first automatic door was used in the royal library of China's emperor Yang of Sui Dynasty. Most doors were made of wood- but metals were mostly used for public buildings. In Renaissance Italy, door casings were an element of surprise and impression. These doors were decorated with columns and pediments in plain walls. New materials and resources like modified and stained glass soon came to light . Over time there were variations of doors-glass doors, and soon- revolving doors.

                    The new revolving door helped solve problems like heat exhaustion and negative air pressure in buildings. Later, around the 19th and 20th century different forms of doors evolved: panel doors, flush doors, French doors, pocket doors, etc. Additionally, gateways from sacred temples were also forms of very-old doors. They used cloth that would serve as a entryway and they also soon "upgraded" to elements like stone and such materials.This changed architecture because it revolutionized small elements of buildings. In my opinion, doors have evolved greatly over time. It is not a new invention, but it is a everyday, ever-changing invention.
