Home Wall

Hello, looking for a bit of input on putting in small home wall to train and introduce the kids when ready. Looking to see if you all think it is a reasonable spot and size.

The baseboard is 8.5 feet wide, baseboard is 4 ft tall, slanted ceiling is 7ft in length, overall ceiling height is just over 7 feet, and length of ceiling could extend as much as desired. Thanks again for your input.
