I never use the door casing on those attic stairs- I use the flattest moulding I can find that will hide the gap between the drywall and the stair. I also paint them with ceiling paint not trim paint. If you really wanted to do construction you could build a wing wall at the end of the cabinet run to bring that flush to the left wall and then put in an arch. But I wouldn’t.

In addition to Hallett’s advice above for camouflaging the attic door, consider painting the brown entry door the same color as the others. Get rid of the string hanging down for attic access and make some sort of hand pull that can be operated from a ladder. It looks like you have the head room for two beautiful pendant lanterns and they will draw the eye lower than the attic door, further camouflaging it.

That is one long and boring hallway. You could also go totally overboard with that ceiling: For example, you could cover it with wild wallpaper, or paint rectangles of different colors. To be effective, you would need to remove the molding around the door for wall paper or if painting rectangles add molding to them. You could also lower the apparent height of the ceiling by painting or papering the top 12 inches of the wall also.

Echoing what ginatay said — a ring instead of the string. You don’t even need a ladder, just a pole:

I’d add some art and a pretty runner to the hall, as well as interesting light fixtures.

Yes I need to access my attic lol. I do love all the ideas. Thank you to all who took time to respond.

I’m definitely going to sand the door and moulding down and paint with ceiling flat paint. I’ve ordered the hook and pole :) I love the arch idea! Maybe one day for sure. I’m getting a new front door and will paint the Greek Villa. I’m still thinking wood planks somehow on the ceiling with semi flushed lanterns maybe. Perhaps some thing fun? So many doors. Should I paint them a color?
