Basement study room, how to get as much natural light in as possible?

Hello Perlenmann,

Or are those the mirror light shafts?

No; what you mean are daylight systems that work with prisms. They are very popular for lighting stairwells and are available from almost all roof window suppliers.

Kind regards

Hello,

We would then have to do without the light wells in favor of a terrace on the south ...

No, you don't have to with this system - they are walkable

Where are such mirror light wells priced roughly compared to "normal" light wells?

The supplier has also considered production in Germany; that was my last info - this way you save the annoying customs fees. If I remember correctly, the price at that time was in the range of TEUR 1.5-2 per light well. Google Heliobus; if you need a contact person, I can gladly give you the contact details.

Best regards
