Trappuddens Bad & Bastu
A bathing and sauna retreat situated at Trappudden, exploring how Allemansrätten can be reinterpreted within an increasingly urbanized society. The project blends local materials, craft, and spatial intimacy to create new forms of shared public access.

Reading the Coastline
The project is located on the coastline of Trappudden. The site is shaped by exposed rock, wind, and changing water levels. Before designing the structure, the focus was on understanding how people already move, swim, and rest along the shore.

Concept and intention
The intended feeling of the place — calm, accessible, and connected to the water. The structure supports activities that already exist at the site and enhances them with simple architectural tools.
The project uses stone found on site as a reference for color, texture, and construction approach. The gabion walls reflect the natural character of the coastline rather than adding new material expressions.
The Sequence of Spaces
The building is organized as a linear sequence: arrival, shared outdoor areas, and enclosed warm spaces. The diagrams show how people move through the structure for swimming, resting, or using the sauna.

A Quiet Assembly of Materials
The construction is kept straightforward: gabion walls form the main support, and timber frames define the interior rooms. This exploded view shows how the deck, walls, and roof relate to each other.

The Building Made Legible
The drawings illustrate the building’s scale and its direct connection to the water. Sections highlight how the gabion walls create thermal mass and how the chimney becomes the core of the warm rooms.

Where Material and Function Meet
This section drawing reveals the layered construction of the sauna wall, including the gabion stone façade, insulation layers, vapor barrier, and timber interior cladding. The detail highlights how the chimney is anchored within the gabion mass, using stone as both load-bearing and heat-buffering material.

With an intention not to dominate the site, but to create small moments of shelter,the elevation studies show how the building sits lightly on the landscape while maintaining a clear rhythm of stone and timber
A Quiet Presence on the Coastline
This render explores how the structure blends with the muted tones of the coastline.
The low height and stone texture allow it to feel like part of the terrain.
