Hey Kelunaboy,
Congrats on the new home! Good to hear you negotiated trackage rights during the purchase. I worked on something close to your room and track plan a few years ago.
I used narrower tables, the closet became a place for a storage yard and we left an aisle for the bathroom as the door opened inward.
new house, smhewhouse - you can patch or repair any holes that make in the walls.
The room was 12' x 17', the layout table was fit in to avoid doors and such. This was a second "master bedroom" in a New York city townhome. You can check it out with the attached pics.
yes, it will take you some time to master the layout software , but shorter than other types of software.
Have fun!
