Hi Dan, yes the drawing outline represents the room walls, either 14X14 or 12X17. The plans are scaled differently for the web page presentation (which is done by the web page hosting software, not by me), so they look like they are different sizes.
Actually, the track plans are exactly the same, just tilted.
Access is indeed different for the two room orientations, better for the 12X17 I think. But the 12X17 has three access areas, and depending on where the door is, one has to travel under the layout to reach the other access areas. I would build the layout a bit higher than average, perhaps at 48", and then use a low stool or lowered office chair on wheels to scoot while sitting to get between the access areas. -doable, but perhaps not ideal, and depending on the room access, one might end up doing a lot of "scooting" to get around. Perhaps best if the floor is not carpeted, to make the rolling easier.
