It might be nice to add some texture -- wood in a finish that works well with the view and rest of the condo. It's such a nice feature wall, that would make it pop.

so you're going to do the sofa here? like this?

can you shoot another pic from the other direction? if you put a sofa here, won't it take up the space? is the glass wall behind it actually a wall? so it won't matter if the sofa takes up the entire walk-way area?

i suppose you could paint the wall a darker color, do a wall treatment like wood, or even tile.

Otherwise, it would just look like this,,,,which doesn't look good
