Abstract:The notion of bluespace in urban planning and design discourse is relatively new, as is a whole-systems approach to con-
sidering water spaces as integral to overall city form and the urban experience of citizens. This paper investigates the role
of blue spaces in port cities, delineating the critical relationship bluespace has to traditional green and grey urban spaces.
The concept of a sea-to-land continuum, using a matrix that defnes urban space types graduating from sea to city, is de-
veloped and tested at case study sites in the port cities of Auckland and Oslo.
