This house looks so familiar! Maybe the builder went crazy in our area too. :) I actually like the design myself.

paint, bahama shudders!

The porch over the entrance bothers me; it has a slightly Motel look to it for some reason.
Shutters don't belong on this house, but better use of color and trim do.
So even before considering color, which needs to change, I would put an end wall on the street side of the balcony like this:

Then, the first floor garage end is still basically unbalanced; the skinny poles supporting the porch should be beefed up and made more important. Optional: wrap corresponding trim around the rest of the entrance portal to emphasize the entrance to the house.

Carrying that trim over to the entrance portal does seem to make quite a difference. And if you wall off the "motel balcony" but add the same diagonal windows there that are to the left of the entry, it might look more balanced and give you some nice light without sacrificing privacy in the master. Lots of potential!

I would suggest that you contact an Architect or designer in your area for a preliminary consult. They may be able to provide better input on the design potential of the house by assessing both the interior and exterior of the home. They may be able to provide suggestions on how to address the proportion/balance issues in the facade based on a more thorough assessment of the home.

I love the garage doors in the post above. I also think you could do the small pergola over them. That is a start..and, your porch posts look like toothpicks. they need to beef up.

Our house is just like yours, but opposite view, without the porch and large windows over the entry! Really like your windows over the left.
