Options to update a 50's MiMo style 2-story home

[Marshall Swatt]

We purchased a long neglected 50's MiMO style house in our neighborhood in upstate NY. I'd like to improve the facade and give it more dimensionality. Anyone have experience improving facades? Or any advice on resources or books I should look at to get ideas, someone I should speak with? Instagram/online isn't helpful. I'm reaching out to a couple architects, but would still like to be more knowledgeable about the wood sheathing/cladding options myself. We may need to add insulation too.

-I'm open to adding horizontal or vertical lines using wood, adding a MiMo style brise-soleil or similar treatment over the entry and 1st floor windows
-I'm looking to replace some of the original facade windows, enlarging the narrow living room windows and the window over the existing staircase.
-other suggestions welcome too!
