other points to note
don't cut any timbers in isolation i use 4x1" for the slats at 60 to 75mm spacings
start and finnish with a slat and screw a bit off 2x1 or 4x1" flat centrally down the beds full length underneath to spread the load
there will be loads off offcuts from the slats that will be usefull on the ladder
get your matress first then make your base 12-25mm bigger
and secure a freestanding bed to the back wall to stop the noise and for peice off mind as climbing the ladder will pull the bed away from the wall a bit
