The period from the end of the 19th century to the beginning of the 20th century is called Art Nouveau. It featured by very distinct kind of ornamenting. Design was very bloomy and used many floral elements. In most European countries it came to an end with the beginning of World War I in 1914.
In this context Antonio Gaudi was a child of his time, but he was very different and on his own with his style.
Also, in his style of designing houses. Each room has at least one window. The windows of the owners rooms, like dining room, living room or office are to the street, while the kitchen, bathroom or laundry room have their windows to one of the three atriums. Even the sleeping rooms for the servants got a windows – extremely rare for that time.
Beside the door you can find a phone, connected to the door in the street, to speak with a visitor without opening the door and – most surprisingly – open the door remotely.
Also, have a close look inside the bathroom and the equipment you can see: a bathtub, a water toilet and a bidet. On the other hand pay attention to the equipment of the laundry room.
Don’t forget, the house was built from 1906 – 1910.
