This does not look like a picture of the full facade. A full view so it has context with its surroundings would be great. The most glaring is the right picture windows not lining up with each other. Why is that? I would spend as much money as needed and fix that with either moving the lower window OR replacing the upper windows so that they make sense. Change it somehow as that right now, IMHO, is a glaring error to this type of facade. That needs to make sense in this type of architecture.

I like the simplicity not the window mix of styles and I probably would do windows in the garage doors but not sure. It seems you have no yard at the front so usually landscaping is how you bring life to a simple facade . IMO leave the actual building alone anything added on it will not be a good look If you google cubist homes you will notice the facades are not messed with .I think it could have been built with a more interesting facade but too latenow . This type of landscaping might work but withut context hard to say. IMO do not touch anything now unless you are willing to fix the window issue.

I'd fix the misaligned windows on the right and add a whole pile of colorful (and zone-appropriate) landscaping.

Spend the money on a unique front door and garage door. If climate allows use modern pavers for driveway/walkway and enhance the whole front with well designed landscaping.

Are you in a country where brighter colors are often used? Are Mondrian or Barragan inspirations?

The blah gray scheme is industrial incineratoresque offensive. It might as well be an aluminum can recycling center.

You need texture and color. Stone, wood, copper metal, greens, blues, etc. A simple material and color blocking design.

Can you step back and take a picture of the entire front of the house straight on, no angle.

Full picture needed. Definitely a different front & garage door needed along with a different color scheme & landscaping for starters. Where is this house? Country? Climate? Lots of unknowns.

@3onthetree has come up with a genius solution to address the misaligned windows and make them look intentional. Her siding material adds textural interest. What would happen if you made her window siding material and the front and garage doors a burnt orange or lime green? Sorry, I don’t know how to mock—up photos.

I do like that from @3onatree I for sure would never add stone to this facade .I do however want to undertsand why posters ask questions then never come back. I always wonder do they take days to answer texts I think not .

Agree with Patricia. MIA OPs are becoming an epidemic on this site

IMO wait to post until you have time to deal with it .

Gee, when commenters say things like, "The blah gray scheme is industrial incineratoresque offensive. It might as well be an aluminum can recycling center," I wonder why OPs stop following the thread they started.
