The offices of advisory firm MPrime are organized across three distinct levels, on the ground floor of a 1970s apartment building.
At ground level, the reception, open workspace, and presentation area are arranged in a continuous layout. The space opens toward the city through double-height glazing. Transparency operates not only as a visual condition, but as an active medium that connects the interior to the urban environment, introducing light and movement.
A circular metal staircase leads to the mezzanine, which accommodates two enclosed offices. Their placement maintains visual contact with the shared workspace, reinforcing a sense of collectivity.
The basement hosts the secondary functions — kitchen, WC, and storage — organized through a clear linear duality of white and green.
The upper structure is defined by a white envelope. Its central element is a new glass block volume: a solid yet permeable mass that slides in from the side elevation and occupies the rear half of the plan. This object operates as an intermediate filter of transparency, modulating levels of privacy without interrupting visual continuity.
A grid of black metal elements defines the geometry of the translucent volume and reinforces its presence as a distinct spatial entity. The volume is not treated as a simple partition, but as an active component of the design, organizing and rearticulating the void of the double-height space through a relationship of interaction.
