Architecture, Building and Structure Design Interelationships Residential Complex by Constantinos Yanniotis Interelationships is a pilot, sustainable, collective housing, supported living complex that hosts vulnerable groups of people living in a collective community. The social impact of the project is important because it (re)integrates these people with work and joint participation in a multitude of activities with city residents. It may thus become a cultural attraction where interpersonal relationships develop through social, cultural and leisure revenue-generated activities. Fundamental aim of the project is to demonstrate that UD fits into buildings or complexes with modern aesthetics.
