Other than the master bathroom, is there a bathroom on the main level? (It was hard for me to discern, but I didn't see one).

And, if you have a pool, will you have a separate pool house, or not? If not, where is the nearest toilet and shower to the pool?

I would put doors on the J&J's bath/shared closet. The question of if you need them/want them can be asked of the local inspectors--what size fan, and in which rooms, will they require for that space. In my area, they would have required a fan in the toilet room, as well as the "bathroom" and the bathroom fan would have needed to be sized sufficiently to pull air for the ENTIRE area including closet space, since there are no doors...

The "flat" roofing will actually have a slope of 1/4" per foot. The deck can be flat and the insulation sloped. It can slope to perimeter scuppers or an internal drain so the roof edges can be level.

I would not use manufactured residential metal roofing on a slope of 1 in 12. Below any metal roofing I would install a layer of Ice & Water Shield. At 1 in 12 you may need to use a system that can be field soldered. Metal roofing should be much more expensive than single-ply membrane roofing. The only maintenance needed for membrane roofing is checking the seams each year and keeping the drains working.

Have you reviewed these issues with a roofer?

Kirkhall,
Sorry, I realize my hand-drawn plans are a bit difficult to see, but they have more details than the plans given to us by the architect. There is a powder room off the foyer and an attached poolhouse off the back of the garage by the mudroom.

Thanks for the note about doors between my girls' bathroom and closet. We have been debating the doors and will prob include them.

Do the girls share clothes? If not, I would put in separate closets. I might anyway, just to decrease the traffic in the bathroom. Seems to me if one kid wants to take a long bath with the doors locked, the other one can't get a change of clothes.

You have a climbing wall in the house? Sweet!

You have plenty of room to make the basement powder room bigger. In fact, a second PR down there might not be a bad idea - I can see room for a HUGE party down there!

Annkh,
Yes, my girls are 19 months apart and are the same size. My wife and I are tired of figuring out whose closet to put clothes in. I think the climbing wall will be cool too! Yea, we have the room to make the basement bathroom bigger, but should we? We have the occasional party (max one a year), but don't think a second bathroom would be used more than once a year. May make that bathroom a bit bigger though.

My twins are 12 and still the same size and everything goes in one big closet. Then they just battle it out.

Very cool house. Different but good.

Is the outside Dryvit? I don't know what your propert in Il is like but be careful. Woodpeckers love this stuff.
