Asked by a friend who owned a clothing boutique in Sydney to design the interior, the Andoni Boutique was Marc’s first interior design project. The budget for the project was small and Marc faced numerous challenges, in particular, obtaining planning permission to reconstruct the and replace it with a glass panel. Because the shop was on a street in Sydney where there were no existing fully glazed facades at the time, the local council attempted to block the permit. To appease the council, who forbade the glass from continuing right down to the sidewalk, Marc built a plinth under the major part of the facade to raise it off the ground.

Marc designed a minimalist interior, with concrete floors, white walls and lighting that resembled portholes made from spun aluminum.
