Originally built in the late twenties and extensively renovated in the sixties, this house is up for its next big intervention to make it fit for the 21st. century. By adding an extra floor on top of the flat roofs, a completely different functional arrangement has been established. The shape of the rooftop addition negotiates the two different roof pitches and ties together in one clear form the three consecutive extensions that have been built since the sixties, with the profile of the former garage still visible in the facade.
