Soldagen: In the Interval

Vindstad sits at the head of Kjerkfjorden on the outer edge of Lofoten. There is no road: everything arrives by ferry from Reine onto a small quay, and the only buildable ground is a narrow shelf of grass between the mountain and the sea. For around three weeks each December the sun does not rise at all. Soldagen is the day it clears the mountain again.

The GENDO 48 brief asked for a bathhouse for the village first and visitors second, in ordinary winter use. Our proposal sits at the intersection of shelter, exposure and light. Rather than treating the polar winter as a problem to be lit away, the concept works with the absence of light: how a building can hold warmth and company through the dark, and make the return of the sun an event you can feel from inside.

Before drawing, we built a panel of AI agents on the competition brief and a library of research into circadian light, thermal comfort and restorative environments, and asked them to help form hypotheses rather than images.

Light

What if the architecture allowed sunlight to be perceived before it could be physically reached, extending the interval between seeing, anticipating and finally occupying direct light? A gradual process, an anticipated arrival, light and dark read as positive and negative space.

Thermal depth

Using spatial depth to mediate light, exposure and temperature. Layers, thermal depth and horizontal views, with the building as a thermal blanket between the exposed and the retained.

Framing the landscape

Revealing how the landscape receives light. Connecting land to sea, the circular relationships between them, the settlements kept close to the fjord, and the importance of sheltered zones.

The first hypothesis came from a chain the research kept returning to: light timing sets melatonin, melatonin sets sleep and wake, and from there alertness, mood and cognition follow. The building cannot change how much daylight there is. It can change how that light is met, so a set of working assumptions was fixed early and every plan was tested against them.

The building runs on the day rather than the clock. Midday is clothed, communal and social, the shared rooms and the warm bath full of the village under the brightest light the site has. Evening turns individual, lit blue or barely at all, so the body is allowed to wind down.

Light through the day

Warm light in the morning, bright light at midday, blue light or its absence in the evening.

Use through the day

Clothed, communal and social at midday. Individual, quiet and unhurried in the evening.

Views

Horizontal views over the bay. Skylights where the building meets the mountain.

Orientation

Open towards the water. Closed towards the mountain.

The light hypothesis becomes a route. The passages between the bathing rooms are lined in copper and run towards the water, and at the end of each the opening is framed so that the peak across the fjord is caught in it. On Soldagen the sun lands on that peak long before it reaches the shelf the village stands on. You see the light, you walk towards it, and eventually you stand in it. The interval between those three is the subject of the building.

Steam from the baths drifts through the passages, so the copper warms and darkens with use. Thresholds are wet stone. Nothing in the sequence is meant to be crossed quickly.

In section the building is pressed against the rock. Its back is closed and solid, with light arriving from above through skylights. Its front is a row of curved concrete hoods lifted over full-height glass, looking horizontally out across the bay. Below them the bathing terraces step down towards the sea, and the warm pools spill over their edges onto the rocks, so that from across the fjord the building is marked by the steam rising off its water.

The last step is the sea bath: from warm water to cold, from the sheltered terrace to the open fjord, under the widest sky the site has.

The brief is explicit that winter here is violent: wind, salt, storms, and snow on the ground for half the year. The building is concrete and copper because both are improved by that. The eaves are cast as a single curve so water runs clear of the glazing; the copper panels sit on a rough stone plinth and are left to take on the marks of the weather, and of hands.
