Lisbon and its “new avenues” (built in the beginning of the past century) are always a challenge for an architect.

Lisbon’s Stone Block is located in the corner of two major streets and that position is somehow special in the relation that the building it-self creates with the “urban net”.

The idea/concept of the building is based in a “mutant facade”: a skin in stone, almost metamorphoses and movable. We can say that the building is an urban sculpture that transmits several images accordingly to its use: By night the light radiates from the apartments and by day the building is perforated by it in a different way – the natural light passes through the openings in the movable panels, allowing the control of light in the interior of each apartment.

The apartments present a plan where the living room centres also a will to move and transform – through opening or closing the panels in the façade it’s possible to create different spaces in each apartment.
