In my new-build house one of the upstairs bedroom windows has ended up with a bottom edge a little higher than the mandated 1100mm - which was picked up by the Building Standards officer on his sign-off visit. The architect's drawings were correct, but the joiner got it wrong by about 100mm. Moving the window down will be a nightmare [it's a Velux in the slate roof], the joiner/builder has retired, and the mess/disruption would be phenomenal [the house is finished, plastered, decorated] , so I want to install a step under the window to raise the floor height.
The Technical Handbook simply states the 1100mm rule and is silent on the use of a step, but the officer says he thinks it's unlikely to be approved. I've seen a precedent for using a step approved/recommended by an authority in England, but that won't wash with the inspectors here in The Highlands.
Does anyone have any advice or, better still, a real example of where this approach has been signed-off in Scotland?
