The North Pier
Hybrid Coastal Infrastructure as a Surf Facility at Wijk aan Zee


This graduation project explores how civil infrastructure can be transformed into architectural space. Initially planned for Biarritz, the location shifted due to COVID-19 travel restrictions to Wijk aan Zee — a place with a unique tension between heavy industry, natural dunes, beach, and sea. 

The North Pier, extending perpendicularly from the coast, creates a sheltered current where sand accumulates and consistent waves form — ideal for surfers and other adventure sports. The Province of North Holland has designated the site as a “durfspot” (challenge spot) with potential for recreational development. At the same time, there are plans to strengthen the pier and integrate it into the primary flood defence system in response to future sea-level rise. 

Research Question 
How can a civil structure be transformed into architectural space, and later be reabsorbed into its original civil function? 

Design Strategy 
The strengthening and heightening of the North Pier uses the caisson principle: modular, prefabricated concrete boxes that are submerged and filled with sand. This repetitive structure of caissons and caisson sleeves forms the spatial framework. Within a 5x5 meter grid, a sequence of rooms emerges, accessible from walkways running along both sides of the dike. Strategic openings, sliding doors, and skylights create flexibility, accessibility, and shelter. 

The extra layer of caisson sleeves in the future elevation is used for a surf facility with sleeping cabins, sanitary facilities, changing rooms, a surf school, and a pavilion. Stairs and canopies link the structure to the beach, sea, and dunes. When the dike is raised, the openings are sealed, and the rooms are filled with sand, returning the structure to a purely civil role. 

The architecture is simple and robust, attuned to wind, light, sand, and sea — balancing comfort with the raw outdoor life of surf culture. 

Conclusion 
The North Pier demonstrates how civil engineering and architecture can reinforce each other for social value. Its repeatable, flexible structure offers inspiration for coastal locations where flood safety and recreation intersect, opening new perspectives on the dike as public space.
