The architectural concept draws from naturally occurring seawater pools that form between rocks as the tide recedes. This idea is translated into a three-tiered structure embedded within the breakwater, each level organised around a single rock. The upper platform forms a viewing deck inspired by the bow of a boat, the middle accommodates the main geothermal pool, and the lower level creates a cooler beach pool that mediates between hot water and the ocean. At high tide, waves reach the structure, while at low tide smaller pools form along the shore, reinforcing the relationship between architecture and natural processes.

The structure is constructed in marine-grade concrete, designed to withstand the harsh coastal environment. Prefabricated elements were used to ensure quality and efficiency during construction. Rocks from the existing barrier are integrated into the pools, strengthening the connection to place. Untreated geothermal water is sourced from Deildartunguhver, Europe’s most powerful hot spring, and channelled directly to the site. Supporting facilities are integrated into the repurposed substructure of the adjacent stadium, minimising additional footprint.

Funded through a collaboration between the Jón Gunnlaugsson and Guðlaug Gunnlaugsdóttir memorial fund, Akranes Municipality and public grants, the project began with a simple brief: to place a hot pool by the beach. Its impact has extended beyond this initial ambition. Guðlaug has strengthened the town’s identity, increased visitor numbers and contributed positively to the local economy. At the same time, it remains a modest and robust intervention.
