Julia appropriates our expectations of what a “wall” is and how it should function. Externally identical to a genuine concrete wall, Julia’s walls are simply artifices. They are made of foam, papier-mâché, and other materials that Julia says, “imply wall and wall pieces, but are contrary to their functionality”. This is key to her work. The materials Julia uses mimic concrete walls. In fact, they are diametrically opposed to concrete, both in terms of utility and functionality.
