It’s rather nice to work in your own home office. But sacrificing an entire room in your house for an office? The owner didn’t want to do that. Since there was so much unused space in the cellar, the owner turned some of this into an office. Of course, you can’t have an office without daylight. As a result, the Heliobus daylight shaft was used to create a connection to the outside world and bring natural light into the room.
