Above:  the water of the mouth of the river can be seen between the piers and the edge of the cottage.  The sense of this structure is that it is grounded at the right, and floats out toward the canal  and the bay.  The materials and composition move from a massive, solid system at the right (east), to a light, more delicate system that disintegrates, tapers and floats out toward the dense mangroves and the water at the left (west).
