Like other chinese cities, Beijing has entered since the XXIth century an important urban renewal phase. This phenomenon has been exacerbated in the hundreds of urban villages on the outskirts of the city. The relentless demolition of entire neighborhoods raises questions about the future of urban villages in Beijing. The village of Caochangdi is locatd in the heart of a pocket defined by the interchange that connects the impressive 5th ring with the airport expressway. Originally composed of courtyard houses and farmers, the village metamorphoses with the massive arrival of rural migrants which coincide with the arrival of an artistic community. A first phase of renewal occurs: migrants and taxi drivers crowd together in illegal constructions. In 2009 is programmed the tabula rasa of Caochangdi. Faced with the real-estate pressure, how is it possible to preserve the extreme urbanity of its streets without dislodging the population during this second renewal phase? The densification needs of Caochangdi will bring it to a saturation state . It will extend outside of its physical borders in order to merge with its two direct neighbors: Nangaoxiang and Dongxindian. The focal point of this connexion will be the construcion of a multimodal transport node, creation a new polarity in the conurbation. The project becomes then an essential condition to the advent of a “Super urban village”.
