Built-in Inspiration

A friend and his family will be coming to visit for a long weekend, the end of April.  They're gonna visit the Pittsburgh Zoo, and our kids and their kids are gonna have a blast just playing together!  He's hoping to build us (with Aaron, of course) some built-ins for Alex's room while they're here.  (He's a carpenter, with four kids of his own, so that kinda multi-tasking shouldn't be a problem for him. *grin*)  The built-in is going to go along this wall in Alex's room - the one with the window on it.

Alex's room has been painted a pale yellow (per his request demand).  Well, technically he wanted "school bus yellow," but we bought pale yellow.

So ... the room's been painted, the date's been set, and all that remains is me to figure out what I want them to look like.  I want them to be able to "grow" with him, so maybe what's under the window will be a desk area, with space to push in a chair?  I'm not sure.  This morning I decided it was time to search the net for inspiration photos, and here's what I've come up with so far.
(Excuse the poor blog-etiquite, I have no idea where these pics are from, I just did a google search and saved a bunch of the pics.)

Hmmmmm.  Possibly the general idea - but just the part that's on the window wall.

Not bad, if it had some shelving too.  My kid's got a lot of books.  But the bottom right cabinet would be great for storing his board games.

That's kinda cute - maybe a little too "modern" for the rest of the furniture in the room.  Maybe it's just the color scheme that's throwing me.

That's not bad.  Maybe if the dimensions of Alex's room were different.

So cute, but not for him.  That bookcase's the same shape as the dark-wood ones that are in his room right now.

Interesting.  That'd be quite cute for a play room, but the table'd take up way too much room in a bedroom.

I like this.  Of course I do - it's from the Pottery Barn.  I generally like their stuff.

Get rid of the primary colors - the star pulls, the drums, and the snow.  Then maybe I'll consider this one.

Interesting use of that wall.  It reminds me of something from National Velvet, though.  I have no idea why.

Ummm. Let's pretend I could ignore the colors in this picture.  The built-ins is too boring.

Drool, sigh, I'm in love.  I think this last one might be it.

Hmmm. We have a "contemporary" home, with NO moulding anywhere so far.  I wonder if we could pull that look off?  Maybe they'll need more than just one day to build. Hmmm.
