Swiss architecture studio Dubail Begert Architectes have completed this translucent extension of a residential building in Le Noirmont, Switzerland.

The outside stairwell frees up internal space and is made of a polycarbonate shell that allows people outside to see movement within.

The metal staircase reflects coloured light from the tinted glazed panels that change colour from floor to floor.

The illuminated interior gives the building a coloured glow at night.

Here's more from the architects:


The installation of an outside stairwell allows increases space in the cramped apartments of this building of labour apartments built in 1907.

Translucent polycarbonate shells play with reflections and transparency effects, to give to this volume an evanescent presence.

Inside, floors, stairs and ceilings are made of raw aluminum sheets.

This industrial materiality is clouded by the coloured light through the warm colours of the interior polycarbonate wall.

    There seem to be more windows in real life than on paper…

    Beautiful at night. Not so beautiful during the day. Not very sympathetic to the building it extends. Would it get cold in winter?

      as an enclosed stairwell, the still air would probably help insulate the apartments behind. it's an intermediate space, and not actually being lived-in.

    I get the feeling that it didn't quite turn out as the architect had invisioned it. The render gives a completely different atmosphere then the realized result.
