Previous issue date: 2011-10-27 === This study focuses on the building ensemble of Avenida Roberto Freire, a main road in Natal, Brazil, as a material expression of the confluence of various factors among which the following may be emphasized: high level of accessibility due to urban spatial re-structuring and the growth of the real estate market, in view of the increasing number of consumers, who arrived in Natal within the last decades. The intense urban modification process that has been going on in Natal since at least the 1980s, has engendered the formation of long axial lines which express the expansion dynamics and some of the forces subjacent to it. Avenida Roberto Freire has been an iconic example of an urban thoroughfare where architecture becomes primarily a communication support that can be perceived by fast moving passers-by, what brings it close to the venturian concept of strip (Venturi at al, 1972). The building types that line the road not only respond to the dynamics in process but also contribute to intensify it, as they house a variety of uses which attract people and generate more movement. The dynamics is further strengthened by the action of the real estate business which benefits from the increase of highly accessible locations, and from the private and public investments and incentives to tourism that aim to insert this city into the globalized world. Although the intention of reconstituting part of the history of density increase on this avenue in a diachronical perspective was attempted within the limits of the available references and documentation, the central contribution of this study is to understand the relations between topological accessibility and the typological nature of the building ensemble. By observing the synchronic morphological frame resulting from the spatial configuration analysis pertinent to this avenue (cf. Hillier and Hanson,1984) and the inventory and classification of the building ensemble there existing, this study aims to understand how architecture responds to accessibility in view of the real estate pressure, boosted by a cosmopolitanizing process brought about by the continuous flow of foreign and Brazilian arrivals as visitors, temporary or permanent residents === Este estudo aborda o perfil edil?cio da avenida Engenheiro Roberto Freire, como express?o material da conflu?ncia de fatores dentre os quais se destacam o alto grau de acessibilidade como conseq??ncia da reestrutura??o espacial urbana, e a amplia??o do mercado imobili?rio em face da presen?a crescente de consumidores que t?m chegado a Natal nas ?ltimas d?cadas. O intenso processo de remodela??o urbana por que vem passando Natal desde, pelo menos, a d?cada de 1980 tem engendrado a forma??o de longos eixos vi?rios que expressam exemplarmente essa din?mica e algumas das for?as subjacentes a ela. A avenida tem sido um dos exemplos ic?nicos de eixos vi?rios nos quais a arquitetura torna-se, primordialmente, suporte de comunica??o capaz de ser percebida por passantes em r?pido movimento, aspecto que a faz aproximar-se do conceito venturiano de strip (Venturi et al, 1972). Os tipos edil?cios que ali abrigam usos diversificados n?o s? respondem ? din?mica em curso, mas tamb?m contribuem para intensific?-la e realiment?-la, na medida em que atraem pessoas e geram mais movimento. Some-se a isso a atua??o do setor imobili?rio que se beneficia com a amplia??o de localiza??es dotadas de alta acessibilidade, e com incentivos p?blicos e privados ao turismo, visando inserir a cidade no mundo globalizado. Embora se tenha tido a inten??o de reconstituir parte da hist?ria do adensamento da avenida em perspectiva diacr?nica, a contribui??o central desse estudo ? entender rela??es entre acessibilidade topol?gica e a natureza tipol?gica do acervo edil?cio. Mediante a leitura de um quadro morfol?gico sincr?nico resultante da an?lise da configura??o espacial que cont?m a avenida (cf. Hillier e Hanson, 1984), e do invent?rio e classifica??o do acervo edil?cio que l? est?, este estudo objetiva compreender como a arquitetura responde ? acessibilidade vis-?-vis o desenvolvimento do mercado imobili?rio, impulsionado por um processo de cosmopolitismo que tem ocorrido pela cont?nua chegada de visitantes e moradores tempor?rios ou permanentes, nacionais e estrangeiros
