ᐅ Home Office in the Basement: How to Maximize Natural Daylight?

Hello,

we are planning a passive single-family house with a basement and had initially calculated a footprint of 8 x 12 m (26 x 39 ft). However, we need two studies of about 15 sqm (160 sq ft) each, which I have so far been unable to fit into the floor plan. We originally wanted to place them on the ground floor and first floor, but that just doesn’t work, and we do not want to make the house any larger because it would increase costs. Additionally, we have a very narrow plot, and a larger house would look out of place there.

Now I had the idea of accommodating the studies in the basement, which is planned anyway. Of course, the basement would need to be dry, warm, and reasonably bright for this. Is that possible? How can we bring as much natural light as possible into the basement? Does anyone have experience or suggestions?

Thank you in advance!

Windows, lots of windows

Yes, this will only be possible through windows and using curtains that allow as much light as possible to pass through. It is also best to use very light colors for the walls and furniture. Additionally, avoid overcrowding the room with too much furniture. This will naturally make the room appear brighter.

A true passive house or more like an efficiency house 55 or below?

Apart from the fact that the home offices have to be finished like “regular” living rooms => possibly plan for a floor height increase <= E.Curb is of course right that you can solve this with windows. The question is— is there enough space, or is the garage/parking space planned right next to one or both home offices?

Another solution—though not quite as inexpensive—are mirror light shafts; we have already used them in passive houses.

Kind regards

Thank you! The idea of mirror light wells is exactly the kind of suggestion I was hoping for. I have also considered adding another floor. Fortunately, we do not have any restrictions on building height. The basement windows would then face south and possibly west as well. We would have to give up a south-facing terrace in favor of the light wells, but that space would have been very tight (3m (10 feet) to the neighbor). So we could comfortably relocate them to the west side.

How do mirror light wells generally compare in cost to standard light wells?

Thank you very much for the help!!!

Hello,

I once saw something where light on the roof was collected through lenses and then distributed into windowless rooms via lenses. I’m not sure if it was done using fiber optics or as a focused beam. I don’t remember the name either...

Or are you referring to light shafts with mirrors?
