Purpose: Senior buildings have been designed as purposeful space programs. Therefore the elderly need coherent information about different senior housing concepts. The study seeks to set out a method for measuring the quality level of senior housing. Design/methodology/approach: The method includes measuring four different factors: local services, building and yard, apartment, and on-site services. Measuring the quality level of two separate residential areas and senior housing facilities demonstrates the use of the quality level measurement system. Findings: The overall quality level of Facility 1 was significantly lower than that of Facility 2. The lower quality level measurement for Facility 1 was primarily the result of the lack of premises for lease to commercial or other tenants and the lack of on-site services. The quality level measurement system is a successful tool for assessing the functioning and quality standard of residential areas and housing facilities in the point of view of elderly people. Originality/value: This study has developed a unique application for measuring the quality level of residential areas and senior housing facilities. The measurement system is useful for estimating the quality level of a facility and also for analyzing different quality level factors to identify possible problems. While the intention is to provide a method primarily for expert assessments, seniors and their relatives could also use the method as an aid in weighing up the suitability of different senior housing facilities.
