I began by noting down the connections between the interior surface and the relationship between the internal/external threshold and passage. From this I created 10 conceptual sketches that I thought could relate to the connections I had discovered.

Top: Sketch 1 – level change
Middle: Sketch 2 – Built around each other
Bottom: Sketch 3 – Moulded

Top: Sketch 4 – Era/age change
Middle: Sketch 5 – Change in feeling of environment (busy-quiet)
Bottom: Sketch 6 – Colour connection of surface and surrounding city

Top: Sketch 7 – Broken threshold
Middle: Sketch 8 – Series of thresholds
Bottom: Sketch 9 – dimensions of surface

Sketch 10 – Perspective of surface
Next I selected three concepts to develop a further three iterations for each concept and show how these would function as a door handle.
