The roof extension and renovation of the house began in 2013 and ended a few months later. The unfinished project was left to its fate and was finally sold to a new owner in 2018. We were tasked with continuing the project and quickly came across the hidden problem:
The lack of a second escape route.

Since a conventional solution with an escape staircase along the facade would impair the view of some apartments, we developed a foldable balcony that can be folded out in the event of a fire.
