Mare Liberum (Open Sea)
There is a floor-to-ceiling glass wall that makes up one side of the AHC. Just beyond this glass wall is a narrow space about 1.5m wide that separates the interior of the High Commission from the outer wall of the building. To me, this is the most poignant of in-between spaces, caught between the outside and the inside, perfectly in limbo.
Low, flat slabs have been formed by pouring concrete on the floor and left to harden in the shapes that they have achieved naturally. They are placed in this in-between space - 17 of them to match the 17 sails in Mare Clausum.
