Will you be able to remove the trim pieces and the small bumpouts for a clean wall?

Yes, we can remove the trim and the bump outs. Need to figure out if I extend or remove crown molding. The attached pic of the frame wall is what I originally had in mind but your feedback is good. Thxs for the time.

Sure. The crown molding partly depends on the rest of your home. Is this the only room with crown? Also, keep in mind that the crown could be decorative or could be disguising some cosmetic issues.

From what I can see of your home, the crown does not seem to fit the style.

It extends to kitchen and front room. The plan is to redo kitchen next.

It sounds like you could take or leave the crown molding. Could you show me the kitchen anf front room, please? Thanks!
