What generates hospitality in architecture? How does architecture welcome dweller at the transition boundaries of space? These are the main questions that motivate the work. The object of study is hospitality in architecture, based on the relationship between dweller and place. Amidst contemporary cities that are often hostile, thinking about architecture of hospitality is necessary. The idea of a border, as a spatial cut-out, reveals potential for this investigation because, through its treatment, it is possible the sewing between different spaces, enabling places of welcoming. Thus, the work has as main objective, therefore, to investigate the welcoming of dweller at the borders of space. Some concepts emerge in a relevant way in the understanding of studied relationships, such as the concepts of place, of dwell, of affection and of border. Methodologically, for the case studies, the mentioned concepts are articulated with contextual analysis tools (physical, historical, and social) such as observation sketches, diagrams, dimensioning and collage. The investigation provides, in this way, new possibilities and the necessary subsidies for the analysis of architectural works in search of a hospitality of place. It started from emblematic works, in different contexts and scales, up to everyday spaces in Rio de Janeiro, analyzed in the study cases (Praça São Salvador e Mureta da Urca). The choice of these is mainly due to the collective character of these places, characterized by the presence of elements that offer hospitality to those who dwell it, associated with a favorable context for hosting. It seeks to recognize in these analyzes the gestures that provides welcoming to the place through architecture. It is proposed here that hospitality in architecture occurs through different strategies that operate in different scales. From the body scale, through the building scale, until the urban scale.
