Project story

Rather than plan for eleven programmes, the pavilion offers a 38 by 21 metre clear span, a heated stone floor, and services in the perimeter wall. Everything else is furniture.

In its first year it held a boat show, two weddings, a food market and the municipal budget hearing.

Context

The harbour will flood. The floor sits 2.4 metres above the highest recorded tide, on a plinth designed to be walked over when the water is out and swum past when it is in.

The plinth is the real public building — stepped, south-facing, and busiest in the hours the pavilion is empty.

Materiality

A structure of glue-laminated pine, 21 metres clear, left exposed and unpainted.

Glazing is low-iron and reeded on the west face to cut the low sun without a blind. The plinth is Bornholm granite, split not sawn.

Spatial experience

From inside there is no visible support between you and the water. From outside the roof reads as a single line held at the height of the quay cranes.

At night the pavilion is the brightest object on the harbour, and the city has taken to using it as a clock: lit means open.
