After much humming and ha-ing, calculating square footage of each individual room, measuring and re-measuring rooms, we have decided to forgo lot 96, in favour of lot 94.
It's approximately an extra 250 square feet, between the two designs, for a total of just over 1500 sq. ft. The second set of plans at least means we can comfortably have room for the aforementioned "Oasis of luxury". An example of which is shown below, (these are photos we took at the showhouse, so it may not be exactly as shown in our house - but you get the general idea).
With the new plans the boy gets a slightly bigger room, and my kitchen/breakfast area will increase significantly to the point where I could possibly forego a formal "dining room" altogether and make the "living room/dining room" area strictly "living room/family room" space only.
Truth be told, I never entertain formally, heck if you're eating at my house, you are considered one of the family, in which case you can eat in the kitchen with the rest of us.
