Here are two PDFs of a layout using another piece of software.

Let me see if I can try and walk you through the pictures on my initial post:

Good reference point – the center u walls are the kitchen.

1st picture in the album is the living room (far left, front of the house) with your kitchen to the right and the optional room to the rear.

2nd: dining room, far left of the main house, with the kitchen behind you and the hallway leading to the master bedroom, other bedroom, 11x5 room the garage to the left.

3rd: Combination kitchen and dining room (more center of main house) with the breakfast nook behind you

4th: looking into the kitchen with the living room beyond it, and dining room behind you

5th: kitchen

6th: dining room looking into the breakfast nook, kitchen to the right

7th: Downstairs bathroom to the right of the 11x5 room and left of the other bedroom downstairs.

8th: Hallway. 11x5 room to your left, then bathroom, then other room. Master bedroom is to the right. Garage is directly behind you.
