Beckah Grant Old Waterbed Drawer pedastals- what's the ceiling slants doing? 3 drawer unit from waterbed can be made custom height to accommodate slanting roofline- and make use of 'Wasted' floor space-Would love a deck/balcony over the first floor bedrooms- If they wouldn't throw eachother off or platform dive into the pool or trampoline.....!!!!! I have three sons.....hhahaha

Beckah Grant OR make three Triangles, one for each boy, bath n stairs is the 4th triangle- Closet space above the last/lowest stair level OR the whole square of ' Open to Below' for privacy and noise barrier- heat-loss Stop from downstairs. Make sur U have lots of cross ventilation save on A/C. make 11X7 'Cubby study or Common Area- if you don't want an outdoor access- smaller window less distraction or glare for Video...

decoenthusiaste Do you have enough ceiling space to do this? They can flip a coin every six months to see who gets the top.

Beckah Grant Top? .... help me see it....

judyg Is the dotted line the knee wall?

If so that entire wall could become desks and drawers, with all the electrical equipment hidden. The 11 x 7 area could be just for hanging clothes.
Master Bedroom

Or 3 of these, where each bed has a desk and a bureau.
Lea Industries Dillon Corner Desk Platform Bed

Contemporary Bedroom
Or this, which you can design yourself from IKEA products and it won't be a break the bank solution. You could have a couple of extra beds for sleepovers.

P S, how long until college? :>)

Interiors International, Inc. I like this idea but you would need to adjust it for 3.

feeny My favorite open attic kids' bedroom on Houzz:

jennyhiggins The dotted line is a slanted roof line. Kids are 13, 11 and 9 long time until college. Wanted to build a closet and desk. Just not sure where

Remya Warrior Designs Jenny, the area which you have marked 11'-6" x 7'-1", is it possible to create a long desk? Then atleast 2 of your kids could easily do homework at the same time. If not that space can be used as a huge walk in closet. What is the height of the ceiling at the lowest point in the room?

jennyhiggins i am thinking a L desk in the 11x7 space . There is a window on that wall that covers width
