"There is evidence that caring for green areas in the interior and exterior of a dwelling can become a source of daily pleasure and tranquillity. The focus of our research is upon the influence of green areas on housing’s internal inhabitability. The purpose of this study was to explore people’s emotional reactions in terms of Merhabian and Russell’s (1974) states of pleasure, arousal and dominance, in relation to the existence or not of natural green areas and flowers in the environment, both inside or outside the dwelling, understanding for green areas: grass, shrubs, foliage of plants, trees, and flowers, all of them natural. Additionally, we explored the specific reactions to vegetation, using another scale designed for this project. The sample was nonprobabilistic intentional, consisting of 220 inhabitants of dwellings from Mexico City and St Andrews, Scotland (100 from Mexico City and 120 from St Andrews) with an age ranging between 16 and 85 years. An explanatory, co-relational, expostfacto, multivariate design was used. The instruments were a 59 item Likert Scale (Green areas and housing inhabitability) which was designed to measure the importance of green areas for the inhabitability of the inner and immediate external environment of dwellings. And the other one was the Mehrabian and Rusell’s (1974) ""Semantic Differential Scales of Emotional State"", which measure pleasure arousal and dominance. A descriptive analysis and a multivariate linear regression were carried out to analyze the incidence of culture in people’s interaction with green areas and flowers vis-à-vis the inhabitability of the house as measured through their emotional states. We found significant results with the scale of “Green Areas and Housing” and the “Semantic Differential Scales of Emotional State”. The variables pleasure and activation were significant in relation to perception towards greenery, which entails that the relations between both scales and both variables have a direct relationship between green areas and psycho emotional variables related with pleasure and activation. Concluding, the main contribution of this study was to demonstrate that the restorative environments are important for the housing inhabitability, no matter the size and the nature of the green areas, the important thing is just have them."
