As touched upon earlier, the building's form and surface create an unsettling combination, though this does not appear to be an accident. The form alludes to the familiarity of the domicile, a typology expressed by a hip roof above a square, or rectangular, base. At Prada, the lack of differentiation between wall and roof through materials and openings contributes to this unsettling feeling. This uniform surface articulation, analogous to partially-popped bubble wrap, combines with the bowed glass to create a unique character for the building, based on the time of day, weather, observer's location, and other variables. Overall the skin is the building's most important element, and the most relevant to its purpose: a place for fashion, an "artform" based on skin, surface and their articulation to create a unique character.
