Jeju Notes: On Volcanic Ground

The first thing you notice about Jeju is the rock. It is everywhere — in walls, in pavements, in the rubble of collapsed field boundaries, in the exposed cliff faces along the coast. It is black and porous and rough, the by-product of volcanic eruption, and it absorbs light in a way that smooth stone does not. On a clear day the contrast between the rock and the sky is almost architectural.

Day one: the site in wind

We visited the site on a clear November morning with a strong southwest wind coming off the water. The hilltop was exposed in a way that the site plan had not fully communicated. The existing vegetation — hawthorn and pine, mostly, leaning permanently northeast — had been shaped entirely by the prevailing wind. Standing there, it was obvious that any building would need to engage with this force directly rather than try to ignore it.

Day two: the light at different hours

We returned at dawn and again at midday. The morning light came from the east, low and oblique, casting long shadows across the rock and making the landscape look entirely different from the clear overhead light of noon. In the afternoon, the western sun lit the cliff face and turned the basalt almost warm. These observations would later directly inform the positioning of each room.

On the material of the island

Jeju basalt is used everywhere here, not as a design choice but as the logical response to what the island provides. Walls are built from it. Paths are paved with it. Older buildings sit on foundations of it. Working with local stone felt less like a decision than a recognition of what the site was already asking for. The house would be built from the same material as the landscape it rested in.
