Housing visual quality in urban pattern; Application of isovist method in old fabric of Bushehr city

Visibility is an important factor of environmental quality that has various influences on the quality of neighborhood. This paper aimed to find the relationship between urban form and visual quality. A public space with a spatial configuration in one of Bushehr city's neighborhoods was selected as the case study. Bushehr city is surrounded by urban development and the sea. Compact urban space, squares, long and narrow streets shape this fabric. Correlational research method was used with Isovist tool to evaluate visibility. A grid analysis and two paths inside the fabric with different urban forms were analyzed using Syntax2D software. The results show that the paths with different urban forms have various visual qualities.
