daylight shaft

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.

Up to 20 x more daylight

Fits every shaft

More living space

How it works:

  • A mirrored module will be added to your existing light shaft.
  • Each module is custom-made and therefore can be made to fit in any shaft.
  • Assembly only takes a few hours.
  • Your room will be flooded with real daylight and you even have a view of outside.
  • Thanks to the ventilation frames, the basement is also provided with plenty of fresh air.

That’s how it goes:

  • We measure your existing shaft. Based on this, we generate your personalised quote.
  • Our daylight Mobil shows you the effect of daylight live, on site.
  • All without charge or obligation.
  • In all of Switzerland, whether at home or in your holiday home.
