Thank you. Yes, it is beadboard!

There are multiple doors into the carriage house to accommodate the different uses. There's a "people door" into the main garage and up to the second floor studio space from the garden side, as well as a door that connects into the potting shed portion to facilitate access for wheelbarrows and similar larger tools.

What a beautiful wall color. Do you recall the paint name/manufacturer? Beautiful design.

Gee, I'm sorry. I can't find the color name and number, but I'm sure it was Benjamin Moore.
