Idea file: BIRs in boys' rooms, under the lower ceiling

The boys' rooms presently have sloping ceilings, being as they're immediately under the roof. At their apex, the ceiling is around 2.2m, dropping to 0.9m at room's edge, 2.9m away (ie roof slope of around 24°). With the top popped, most of the ceiling will be high enough that it will be irrelevant. But for the 800mm or so nearest the outside wall, the ceiling will be low enough for them to potentially hit their heads.

So it makes sense to put something there which occupies the space, and stops them walking there and sconning themselves. The two obvious answers are either shelves or built-in wardrobes. At 800mm, it's a bit deep for useable shelves, but perfect for a BIR.

As boys, they don't need much if any full length hanging space. They need shirt/jacket depth (ie min 900mm from rail to floor), plus drawers for socks, jocks, t-shirts, casual pants, and sports gear.

So this kind of idea, but a heck of a lot more efficiently done, might work:

This is a hallway option for coats and boots and gloves and such.

The same website shows some (garish) options for sliding doors for irregular rooflines. I'm not quite sure how they operate, given almost all sliding/rolling doors I've dealt with have been hung/suspended with runners at the bottom to just keep them in line.

(I think the answer is that the shorter panels are all attached/can't be moved separately, and the full height bit of the tallest one is the one fixed at the top.)

Or this, but with drawers, rather than shoe shelves (how many pairs of shoes does one person really need?).

Here's another

So here's my first attempt, using rough measurements/guestimates.

And now with cupboard doors (although with limited clearance, they might need to be sliding doors with an open shelf above the shelf/cupboard top):

Whadya reckon?
