We are a family of 6 and want to redo the entire family sitting/post-entry first look of our house which has been the same since more than 15 years.

We are redoing from scratch the entire sitting area into a modern style family den area ( wooden flooring, straight line sofas, home theatre). But its all just a plan and subject to changes.

The thing we want to focus on most is the wall we see first when we enter the house. It's 28 feet tall, and will be the accent wall, for anyone entering as well as sitting in the family area.
We have gone through thousands of Houzz photos, called many interior designers home, but still haven't quite found the special idea we are looking for.
We are looking for something that would be the star attraction of the house, something that gets the words like spectacular, magnificent out.

Any ideas, photos, comments are welcome; we would be deeply grateful if someone could help us find what we want.
