As the title suggests, I will be lowering parts of the ceiling (about 60cm from the wall, all around) in the living room to install recessed spots and route video/audio/network cables from the closet.
The tip I've received is, of course, to build a frame along the wall using metal studs as the foundation for the lowering. The problem now is that some investigation with a crowbar has shown that one wall in the room doesn't reach all the way up! There's a gap of about 4cm between the top horizontal stud/chipboard and the ceiling...
Therefore, I can't attach parts of the frame to the wall (to get all my depth measurements to match) and I'm wondering how to go about fastening a 45mm stud to the ceiling to achieve about 70mm depth... What spacers (to build the distance between the ceiling and the stud) and CC measurements would you use?
I also gratefully accept tips on LED lights (GU10 socket) and fixtures for them... With drywall, it will probably be about 80mm deep!
For further study on the subject, I'm also wondering how to know which load-bearing properties apply? Brown plugs and "regular" screws have been purchased. How do I know what weights the screws can handle and how much margin do I actually need to calculate with? (If I calculate generously with margins, one long side of the ceiling weighs 40kg)
