People who live in glass houses shouldn’t throw stones, or forget that they’re literally living in a fishbowl, if they have any modesty at all. Designed for a steep plot in Zurich, this ultramodern angular residence by L3P Architekten boasts all-glass, entirely transparent exterior walls that give the outside world more than a glimpse into the life of the family who lives there.

Naturally, you can’t be too concerned about privacy if you live in a house like this, but the architects have taken a few steps to provide a few spaces that prying eyes can’t see. One is setting the house into the earth to create a ground floor that’s partially walled in black exposed concrete, accessible from a subterranean entrance that opens onto the hillside.

The concrete continues throughout the interior, blocking off certain areas of the home without disturbing the views provided by all of that shimmering glass and adding a sense of weight and balance. The interior walls, floors and ceilings are all hewn in this solid material for contrast.

“This work on the vineyard slope copies the logic of a vine: a supporting middle wall, platforms and non-bearing windows follow the structure of the stem, the trunk and the hanging fruit,” says architect Boris Egli.
