So, I'm planning to hang a big projector screen (3m x 3m) - with pole, screen, fixing, I'd estimate 10-15kg - across my garage (for an indoor golf simulator). One one end of the 3m gap I've got plasterboard over breeze block, so I'm fine there. On the other side, the garage ceiling drops down 25cm or so and I'll need to mount into the face of that drop (or have a longer bracket coming off of the breeze block wall to the left).
Where that ceiling drops down, above it is a balcony outside of our living room. I think the drop is because the floor of the balcony is slightly lower than the floor of the living room and any rainwater runs off below it out a drainpipe. The garage door track is hanging from a metal mount that goes up into this 'dropped' area to a wooden stud that is running perpendicular to the garage wall. I haven't chased a cable up that gap to see how high up the mount is vs the ceiling, but perhaps should. Having drilled a test hole from the bottom up into this 'dropped area' there is dense insulation (cavity batt type?) - not sure how high it runs.
I wasn't sure what was behind the plasterboard drop - I assumed a wooden crossbeam but wanted to confirm before I mounted anything. I cut out a square of plasterboard...and behind it is what looks like more plasterboard. Before I just carry on cutting deeper and deeper, I wanted to see if there were any theories or ideas as to what might be at play here based on the info and photos?
With the weight I'm talking about, I might be fine with anchors into the double plasterboard alone, but of course finding a stud somewhere would be better! Am I best to just carry on cutting here to see what I find...? I feel it would be very odd to have this drop without a crossbeam...though this was a Bovis new build in 2016, so not much would surprise me at this point!
Thanks!
