Weiss wanted to create a contemporary extension, but also respect the traditional materials palette. "The chosen materials are an homage to the existing house, but stay in a modern urban context," the architect explained.
Unlike the original building, which has a vernacular roof, the extension features an asymmetric roofline that slopes upwards at two opposite corners of the building to form a butterfly shape.
The two buildings barely touch, so only a single doorway connects to the existing hallway from a new open-plan living and dining room, while two patios slot into the spaces between.
A new staircase leads up to the first floor, where the irregular shape of the roof provides a faceted ceiling over the extra bedroom and dressing room.
There is no connection to the main house from these rooms, but a doorway leads out to a small terrace on the roof.
