We live in a flat above a shop. Our floors/their ceilings are very transparent, noise wise.
The old shop occupants were just a 9-5 clothes shop, very quiet. They left about 7 months ago and its been bliss tbh. Our landlords are a big firm, property agent.
Last week the shop was let, and work has begun. Oh my god has it begun...they're gutting out the entire shop and turning it into a taxi rank. Works began Friday - banging, drilling, shouting, music, sawing...from 8am til 9pm. Then Saturday and Sunday, same hours except they started at 9 on Sunday.
Then today, 10am to 10pm. We can hear EVERYTHING. DS's bedroom seems to be directly above the main noise and he finds it disruptive, we can smell industrial type smells too so had to have the windows open this evening.
They finished around 10, then came back around 11.45 for 15 mins waking DS up.
They left but came back, I've been hearing banging for the past hour. I'm alone and off work at the mo with severe stress and anxiety. My hearts pounding. I'm receiving housing benefit so afaik I couldn't get a rent reduction, but don't really care about that I just want some quiet 
Aibu? Oh, sounds silly but I have cats and all the noise has scared them off, not seen them for 12 hours now which isn't like them.
Am frazzled.
