The model of perpetual explores how shapes and spaces can lend themselves to ideas of continuity and endlessness. The model blow, gilt, explores how layers and finishes are used to hide a simple or unattractive structure. This idea is also shown in the stairs of the above model (right), where a surface of wood covers half the concrete staircase. The balustrade in this model also reflects this core idea. The handrail is detailed in wood while the supports are simple and purely functional.
