Taipei is Open Form. Citizen design reactions communicating with each other and trying to dominate the no-man's land like different plants in the jungle. The layer of illegal architecture combined with other citizen activated spontaneous community reactions such as the illegal urban farms or night markets is so widespread and deep rooted in the Taiwanese culture and cityscape that we could almost speak of another city on top of the 'official' Taipei, a parallel city - or a para-city: Instant Taipei.The official, stiff, hard and boring Taipei is blossoming with Orchid Architecture. The illegal citizen activities are keeping the city alive, they are ruining the faceless industrial city and pushing in the organic.The official city can happen simultaneously together with the Instant Taipei and the official city should accept this as something really beautiful. Let the city rotten, ferment and compost itself. Recognize the illegal architecture as the true force of Taiwanese architecture.
