While research has put the spotlight on analysing informality of the urban poor in the global South, informal housing practices of affluent urbanites have been almost completely overlooked. This article contributes to filling this research gap by investigating illegal housing for upper-income residents in the protected forest area of the eastern hills of Bogotá. More precisely, it quantifies and localizes this phenomenon and, subsequently, it identifies its main geographical, physical, and morphological features. Three interrelated strategic features of such a phenomenon are then recognized – clustering, isolating, and concealing; these can serve as a conceptual guideline for analysing other cases of elite informality in Latin America. They simultaneously underline the existence of a connection between (upper-income) informality and enclave urbanism (gated communities, in particular).

虽然研究重点分析了全球南方城市贫民的非正规性，但富裕城市人的非正规住房实践几乎完全被忽视。本文通过调查波哥大东部山区受保护林区中高收入居民的非法住房，有助于填补这一研究空白。更准确地说，它量化和定位了这种现象，随后确定了其主要的地理、物理和形态特征。然后识别出这种现象的三个相互关联的战略特征——聚集、孤立和隐藏；这些可以作为分析拉丁美洲其他精英非正式案例的概念指南。
