Kastrup Sea Bath in København reconfigures a former industrial edge into a public bathing landscape. A curving timber pier draws the shoreline into the Øresund, enclosing a calm interior pool, a modest beach, and compact service spaces. The project operates as a coastal device that moderates wind and sun, choreographs movement from land to water, and frames communal bathing as a civic ritual.

We shaped the pier as a closed curve to turn a north-facing beach into a south-facing microclimate and to concentrate social life at the water’s edge.

Coastal Regeneration and Public Realm
The project converts a brownfield edge into a civic coastal landscape by extending the public realm into the water. A new beach, a looping pier, and a small service building form a minimal but legible ensemble. Rather than imposing a singular object, the design organizes a set of infrastructural elements that invite use in different seasons and tidal conditions.
The pier operates as an urban armature. It lengthens the shoreline and creates a transitional zone between land and sea where circulation, pause, and outlook overlap. Views are calibrated along the walk: outward to the horizon, across the basin to other bathers, and back to the beach. The ancillary structures remain compact and low, ensuring that the coastal horizon and the primary spatial figure of the bath remain visually dominant while everyday needs are quietly accommodated.
Orientation, Geometry, and Microclimate
A curved plan organizes the pier into a near-circular enclosure that corrects the site’s north-facing orientation. The geometry rearranges exposure, turning the interior into a south-facing pocket that captures sunlight and provides a buffer against the prevailing winds. The enclosure simultaneously softens wave action and clarifies the threshold between the open Øresund and the protected basin.
Sectional adjustments reinforce this environmental approach. The timber deck rises gradually toward a five-metre diving platform, setting a measured sequence from beach to basin and establishing an amphitheatre-like interior. The slope affords clear sightlines for lifeguards and casual oversight, while the elevated platform becomes a focal point in the spatial narrative from shore to promenade to plunge.
A continuous perimeter bench thickens the edge into an inhabitable datum. It supports a range of postures and orientations, from sun-facing repose to shaded lookout, and underlines the social dynamic of mutual visibility. The enclosure maintains the delicate balance between privacy in use and collective awareness typical of communal bathing cultures.
Inclusive Spatial Strategies
Universal access is embedded in the basic organization rather than added at the margins. Ramps integrate with the deck’s gentle topography, and the uninterrupted timber surface allows users with varied mobility to navigate freely, reach the water at multiple points, and share the same routes as other visitors. Railings, landings, and step alternatives are coordinated as a single continuous system instead of discrete accessible “fixes.”
The bounded interior and clear sightlines enable social safety without resorting to partitioning or programmatic segregation. By maintaining a single, legible space, supervision and informal mutual care remain straightforward. The central void reads as a shared resource, where quieter swimming, laps, and children’s play can coexist through temporal negotiation rather than rigid zoning.
Flexibility is achieved through geometry and edge conditions. The pier’s width varies to create areas for passing, pausing, and gathering. The bench line and stepped edges support multiple uses without additional structures, demonstrating how a focused spatial strategy can accommodate diverse activities while preserving formal clarity.
Material and Light as Infrastructure
The structure is realized in Azobé hardwood, selected for its density and durability in a marine environment. In this context, timber serves both as surface and structure, enabling a robust, low-profile architecture capable of withstanding brackish water, variable moisture, and heavy public use. The choice offers lifecycle benefits, including reduced replacement frequency. Yet, it also raises questions about tropical hardwood sourcing, traceability, and embodied impacts that contemporary practice must address through certification and stewardship.
Detailing privileges legibility and tactility. Open joints allow drainage and drying, while exposed fixings simplify maintenance inspection. Over time, weathering unifies the elements with a silvery patina, strengthening the project’s reading as a single continuous instrument shaped by wind, salt, and use. The restrained palette concentrates attention on spatial experience rather than finish.
Night lighting treats illumination as both a safety measure and a form-making tool. Warm reflected light washes the basin interior via uplights aimed at the inner walls, producing even luminance without glare toward the water. Cooler accents articulate the stair and diving platform as a navigational beacon, and linear LEDs embedded along the walkway guide movement while preserving dark-adapted vision. The scheme improves legibility after dusk and during winter while limiting vertical spill, an essential consideration along sensitive coastal habitats.
