Phalanstere
Description
From the Wikipedia:
"A phalanstère (or phalanstery) was a type of building designed for a self-contained utopian community, ideally consisting of 500–2,000 people working together for mutual benefit, and developed in the early 19th century by Charles Fourier. Fourier chose the name by combining the French word phalange (phalanx, an emblematic military unit in ancient Greece), with the word monastère (monastery).[1][2]
Fourier conceived the phalanstère as an organized building designed to integrate urban and rural features.
The structure of the phalanstère was composed of three parts: a central part and two lateral wings. The central part was designed for quiet activities. It included dining rooms, meeting rooms, libraries and studies. A lateral wing was designed for labour and noisy activities, such as carpentry, hammering and forging. It also hosted children because they were considered noisy while playing. The other wing contained a caravansary, with ballrooms and halls for meetings with outsiders who had to pay a fee to visit and meet the people of the Phalanx community. This income was thought to sustain the autonomous economy of the phalanstère. The phalanstère also included private apartments and many social halls. A social hall was defined by Fourier as a seristère."
