Abstract: Tree screens have a demonstrated role in lessening the visual impact of buildings nonintegrated aesthetically by means of filtering façades. This is particularly useful on village fringes and in areas bordering urban green spaces. However, the role of other vegetal structure such as climber species, and their optimal percentage for façade filtering, have not been measured yet. The main objectives of present study were: (1) To guess if climber species have a similar positive role to lessen the visual impact of a façade than tree species, and (2) to compare optimal percentage of coverage for both vegetal structures. To explore them, we designed three percentages of partial-concealment vegetation screens (0% none, 40–50% medium, 70–80% high), comprising tree or climber native species from a study area, in eight buildings from the same region. As a result, 24 final infographics were evaluated by two groups of interviewees: 27 local people and 39 non-local university students. Respondents had to assess the integration of the building in terms of visual preference using an ascending scale with 5 options from “Very poor” = 1 to “Very good” = 5. The results show a clear linear positive response of participants when increasing the percentage of coverage by both types of vegetal screens. However, positive significant valuation over 3 points on average was reached before in tree species screens (3.06, in 40–50% of façade coverage) than in climbing species screens (3.02 in 70–80% of façade coverage). Finally, there was a high consensus in responses when both groups polled were compared.
