The surface of the main stairway of the Black Treefrog artificates the local grapevines, which additionally to the wooden trellis is informing the whole outside of the building as a landscape. The floors, walls, ceilings and steps of the staircase are treated as similar formal elements and are informed with a dense patterning of differently sized and detailed vine leaves. The informed surfaces influence the three-dimensional effect of the whole: the stair construction is seen less as a form in space and more as a programmatic division of entry, splitting access into two zones, one for the ground floor, and the other for the first storey. The missing risers of the open stairs allow an optical connection between these physically and functionally divided zones, and the surface patterns blur the distinction between foreground and background. The constructive and functional parts of the main stair are overlaid with the informed surface – the pattern of grape leaves. Simultaneously, the pattern breaks the construction’s lines and edges to the point that the geometry of the ensemble begins to dissolve. The space is transformed into a sphere. |
