I had the leds on latest place. I find they don't seem as bright but I had them because were a lower build height and I only had a 120mm ish void. Also used them in soffit because rated as you say. 12.50 ish a pop, brushed finish if I remember right
I meant is there a loo further upstream of the connection we are talking about? If not I'd say your fine as the reason you put connection in top third is to stop stuff getting caught
I buy studding a week of so before then sort it when I use. Bananas get used for noggins and bows get used for top or some plate or against walls where I can straighten.
I do think treated is worse for changing
I think better behind a downpipe else you have to start bedding lintel on dpc. Yeh think bricks are around 12m blockwork less like you say. Think you've done right thing
I think masonry now on 12m before gap needed Google it.
I've got a wall just under 12m and I've put one in the middle. They don't cost much to put in so just do it for piece of mind. You need the slip ties with the condoms
I'd maybe change the couplers for flex bands where coming out thru wall. Bit more leway with any future ground movement. Sure the couplers will work fine if you don't want to though
