Decreasing qualitative aspects of residential environments is a real problem in recent public housing of Kerman. This article is concentrated on surveying the impact of in-between spaces on residential environments quality (REQ), to evaluate different kinds of it and to determine interrelation of two main components: residents individual characteristics and characteristics of in-between spaces. Levels of in-between spaces include empirical-aesthetic, performance and environmental characteristics to determine degrees of residents satisfaction (RSAT). Eighteen selected components of in-between spaces quality (ISQ) assess the RSAT degrees in three residential environments of Kerman. Needed data obtained from structured interviews with residents and observation checklists. A direct relationship found between RSAT and ISQ in all three surveyed residential environments. The REQ index is highly and positively correlated with satisfaction of the three levels of in-between spaces and residents individual characteristics such as ownership and residential period.
