With the limited imagery, I would assume the lake is to the rear of the home and this is the front, given the drive to the right? I realize that steel is difficult to modify, and maybe some of these ideas are not possible to implement. Also, this idea may be beyond the scope of what you are looking to do, but I feel this elevation needs something to "define" the entry as such, and certainly landscaping is part of it, but the structure needs visual cues to tell you where it is. The geometry is a bit funky, and perhaps we can play off of this to your advantage. Of all the ideas in this sketch, I would do the roof last. I'm not wild about shingles on a steep sloped roof, I'm more in favor of correcting the scale and context of how you enter the building. I hope this rough Idea, which still needs beaucoup refinement, helps you visualize a few of the possibilities. Happy Houzzing. Go Seahawks!
