Drawings and Floor Layout

I'm pretty sure I've been making plans for this house for 2 years now.  I have sketch books filled with floor-plans and exterior renderings with ever changing layouts and rooms.  I have to say designing a plan from scratch has been very difficult, I'm no architect.  With every plan I came up with I had a problem.  Two floors didn't offer enough room, a 360 house only offered views into the interior walls (no looking out the windows from the inside unless the house was a huge "L" shape) and the bigger I went the heavier it would be.

Finally this past December I visited one of my favourite shops, The Little Dollhouse Company in Toronto and figured out a plan.  I had seen their large Italianate house but never knew it split down the middle! Problem solved!

However, my next obstacle of building a dollhouse from scratch was that I could customize it, and customize it, and customize it, until I never actual got to building because I was always changing things around. Suddenly I needed another cabinet in the kitchen? Well lets move out the wall another inch...

I think I've finally made some concrete plans. I did decide to make the kitchen bigger to accommodate the change in the second floor layout :)  You can see the faint line in the kitchen.  This means that of the foamboard mock up house I've presented here in my last post I will need to extend the back right side out.

The only thing left to plan is the exterior. I know I want a modern dollhouse, but I'm not too sure how contemporary I'd like to go. For example, the Modern Classic;

Or the Contemporary; which features lots of added lines and components.

Both images are essentially the same with three stories of windows for the stairway and the door to the left. It's just the composition of windows and architectural elements.  Which way to go?
