Use of the utility room. Would you move the wall?

Based on the experience we had with my sister's apartment, I would strongly advise against external shading.

In this maisonette apartment of my sister, we installed electric external roller shutters on three skylights.

Since the installation 5 years ago, the manufacturer's service technician (one of the two major skylight manufacturers) has been a permanent visitor in the apartment, since the shutters very regularly stop working.

Each roller shutter has now been completely replaced three times (!!!). However, the problems persist.

In our "old" apartment, we therefore installed a thermal/blackout roller blind from the inside, which has always perfectly fulfilled its purpose.

Thanks for the tip - my gut feeling was similar. I think we will also install an internal roller blind in the utility room upstairs and that will be fine. You don’t spend much time in there anyway. The long room is a bit dark at the back and will get a second lamp.
