Today, many recreational waterfront developments are only superficially pleasant as they lack significant design qualities needed by users. Notions on waterfront qualities create communication gaps between a designer vision and end-user perception. Designers might formulate objectives and ideas on waterfront qualities without adequately understanding the true needs and preferences of users, which encompass aspects deeper than merely visual features. This study evaluated the design quality of the recent development of Jeddah north Corniche. It aimed to analyse the relationship between physical patterns and users activity patterns, which will assert in understanding how seafronts physical pattern produces different social interactions; and how these activity–physical pattern relationships make this public realm work or not. This research employs questionnaires data collection method to interpret the activity patterns that appear to relate with particular use of design features. Analysing this relationship will conclude seafront socio-physical design principles, which take into account users preferences and the unique characteristics of Jeddah location and its Islamic culture, and encourage excellence in the design quality of urban waterfronts; focusing on creating prosperous, sustainable and liveable social environments. In addition, it will add insights and complement the application of urban design theories and practices, which could lead to further studies aiming to improve recreational seafronts design quality.
