This study investigates the influence of spatial configuration produced by the proposed tree planting design on the visual fields of an urban park using space syntax theory. Space syntax theory assumes that an urban area can be represented as a matrix of connected spaces. The quantitative properties of this matrix in the form of syntactic measures can be measured using computer simulations. This research investigates how space syntax techniques can help assess the effect of tree configurations on the social structure of a small-scale garden in an urban park. Such techniques are assumed useful in predicting the social structure of the proposed space and in assessing design alternatives. An experimental study using three different planting design proposals for an urban park is conducted. Data are analyzed using space syntax techniques. Results reveal a significant effect of planting configurations on syntactic measures across the three proposals. This study suggests that space syntax techniques may have a significant value in the assessment of schematic planting design, especially at the pedestrian movement level.展开更多

Due to a variety of reasons, conservation projects failed to preserve sociocultural assets of historic environments. One of these reasons is that experts who involve in the development of historical context completely disregard the communities in such historic areas or their inhabitants. This paper Looks into residents＇ preferences on infiU design projects as part of urban development in historical contexts. It aims to investigate preference ratings of those residents who Live in urban historical context in terms of the quality of new infill design and its relationship to the historical surroundings. This research attempts to evaluate the best design strategies from the point view of the residents as well as the effects of cognitive properties on their preferences. Methodologically, a case study approach was adopted with 204 residents as participants in this survey. The contributive elements that are essential to the quality of fitness are identified through quantitative analysis. The findings of this research indicate that the most preferred design strategies are ＂Literal Replication＂ and ＂Invention within Style＂ from the perspective of the residents, who prefer, to a greater degree, new buildings in historical context replicating something from their surroundings. These findings are useful to experts and major organisations to conduct successful infill development, with consideration of the perceptions of the residents on the changes in their historical context.展开更多

The study specificalty focuses on a housing project catted la cite des 1000 logts, which is situated in a zone d＇habitat urbaine nouvelle in Biskra, a city in South Algeria. The investigation draws on two sources of information, observations of the ways in which the residents use their neighborhood spaces and a questionnaire survey with residents about the perceived adequacy of these spaces for social interaction. Data for the survey was collected from the owners of fiats in the apartment blocks surrounding the open spaces. Housing samples were taken from a total of 1000 housing units identified within the study area. Twenty five percent （25%） of the total housing units were selected. Out of the 250 questionnaires administered to household-heads who were the respondents, only 230 were subsecluently retrieved for data anatysis. Results showed that the high degree of ＂openness＂ of la cite des 1000 logts and the poor quatity of communal outdoor spaces in the area discourage art forms of spatial use and reduce these outdoor spaces to transit areas. Furthermore, findings indicated that the layout of buildings and the quality of common outdoor spaces in residential neighborhoods substantially affect the use of these spaces and the social interaction among residents.展开更多
