Where is the humming noise coming from in your case?

The heat pump???
The underfloor heating???
The ventilation system???
The solar panels???
Or what else could it be???

Maybe not "or," but "and": when a noise source is hard to find, it’s quite possible that it’s not just one, but an interference from the vibrations of multiple sources.

Always turn off one appliance at a time and observe the change.
It might be something completely different: an (old) chest freezer can produce a loud humming noise.
If everything is off, including the main circuit breaker, then the noise is coming from outside or from the neighbors.

And the next company has thrown in the towel 😀 😀
The ceiling installer just stopped halfway through and isn’t coming back. He also doesn’t answer his phone anymore. He used to talk about another big construction site he had to finish.
So far, I’ve paid him €2200 including materials. I think I still owe him money for the work done so far.

Last Friday, someone else came by, started the same day, and will finish the rest for €1700 by the end of the week.

Moving in on January 5 is going to be tight. Remaining budget €23,000.

Unfinished room: ceiling panels, visible joints, loose cables, blue connection cover, two windows.


Shell room with two windows, exposed cables, unfinished walls.


Construction site room: steel ceiling frame, plastered walls, loose cables, and blue electrical box.


Unfinished interior of a construction project with metal ceiling frame, insulation, and exposed cable.


Unfinished interior of a building: wooden staircase, open door frames, and rough walls.

You probably mean May 1st? Meeting the deadline by January 5th (2022) would be quite manageable, I think. 😉

By the way, I really admire how you handle such situations! Did you already have a plan "B" for all the trades? :p

Is the top layer on the staircase landing the screed with that interesting pattern?

It will somehow work out by May 1st ;-)

I didn’t have a plan B, but you just have to see how things progress. Meanwhile, I’m pain-free.

The brown layer is the screed.

Does anyone else have an opinion on my railing? The panels will be filled with glass. Because of the slope, it looks quite odd with the vertical post. However, I haven’t found a better solution if the handrail is supposed to run parallel to the stairs.

Hmm, I think a straight handrail just doesn’t really fit with a spiral staircase. It really doesn’t look great in the picture.
