They do exist, but ateliers in the basement are rather rare. There is an obvious reason for this: the lack of daylight reduces the quality of living. HP Gasser AG recently had to find a solution to this problem in Worb near Bern: The two new rooflights were installed within a day. The access to the underground garage of the residential building could not be blocked any longer. And only from there was it possible to hoist the 6 x 1 m and 1200 kg HPG oecoline vario® flat roof elements to their destination: directly above the client’s basement living and office space. In addition to daylight, the side ventilation flaps also provide a supply of fresh air. And thanks to satinized triple glazing, even privacy is maintained.
