The RV garage dwarfs the house. It would be expensive, but, you could add a second story to the house and that would balance out the size difference in the RV garage and the house. Just an expensive thought!!

Yeah, it’s a monstrosity for sure. Two things working against you (besides the obvious hugeness) are the white garage doors and the driveway.

Decide on some new paint for all the concrete block/brick and seriously consider painting both garage doors that color too. Is there a way to put windows in both garage doors? The same size and height in both. This might be impractical, though.

Is ALL that driveway space necessary? It’s hard to get a perspective from these photos, but it looks like some of the paving on the left (towards the house front door) is superfluous.

If you painted everything from to the right of the tree all one color, it would be a vast improvement. Or, I wonder if there is a way to divide the bay door - paint the top half to match the house (and paint everything above that all the same color) and paint the lower half of the bay door - equal to the same size as the garage door - a slightly different, but not highly contrasting color. Paint the garage door the same as the lower half of the bay door. So I would look more like a 2 story addition with a double garage below.
Visually, more like this, though without the materials changing, just the color blocking:

Are you using it as RV parking? If you don't need the height of the entrance, you could also build a false front of some kind to hide the top of the door but not interfere with it opening, and just use it as a regular height garage.

look at this!

Cool ideas!!!! You guys are awesome. Thank you!

I think painting all the brick a medium to light gray would make it look nice. Then maybe paint the garage doors to match with brown. The gray with brown looks good to me. Adding a barn style light above the smaller garage door would dress it up. If you can afford it, resurfacing the driveway would really make a difference, too. It looks like you have a beautiful house!

Thank you! Would you leave the brick on the rest of the house as is?

I just looked at your pics again and I think if it were mine, for minimal $$, I would decide on what surfaces to paint all the same color and I would paint the top third (or so, line it up with something on the side) of the tall garage door that same color and the bottom of it a slightly contrasting color to trick the eye.
