BYTR Architects have renovated house in Utrecht, The Netherlands by adding an extra floor. The exterior of the new floor is clad in perforated aluminum panels that protect the building from prying eyes and provide privacy. An one more interesting feature of facade design is magic play of light: at night, the metal is lit from the back, while in the day, the perforations provide diffuse daylight into the interior. And could you imagine a modern house without outdoor place for rest? The designers have organized a cozy rooftop terrace where the owner plants herbs garden and enjoy the view of the canal.
