An additional floor without conversion
What initially might sound impossible has been invented in Switzerland: a way to provide house owners with an additional floor and thus more living space. Also bringing an entire Berlin underground station to life.
This is thanks to the worldwide patented, Swiss-made daylight shafts from Heliobus that flood basement rooms with daylight. Up to 20 x stronger than artificial light. Diffuse lighting is enough here. In this way, you pretty much gain an additional floor of living space, which can be used as a children’s bedroom, office, music room or whatever takes your fancy.
