Show all the elevations. All elevations should be taken into consideration when determining exterior design. Don't go out at night and paint your face and forget about what your butt looks like.

Rendering 4 makes the garage door blend in better than the other three renderings. This is a good example of how the garage door of front facing garages is the single largest architectural element of a house and how contrasting doors dominate and overwhelm an elevation.

Your best alternative would be to make the garage doors similar in color and value to the siding of the house so that the garage door blends in, rather than creating a strong contrast and becoming the focal point of the elevation.

The second gable behind the first is unnecessary. I like the vertical siding on 3 and 4.

Is this for your personal use or a project as a general contractor?

Of your elevations, I like #4 the best. The front door is bright so people can find it and the garage door is downplayed.

If possible, I'd do a shed dormer or a side-facing dormer on the garage section so that it didn't have a big triangle over it, emphasizing its importance.

But whatever I did, I'd ditch the nested gables.

Are these in Toronto, by any chance?

I would lose the second gable and the second cladding material on the bottom, and the accent in the gable.

I’m a sucker for red brick and white trim, so I do like #1. I also like more subdued pallets where the garage blends in, so I also like #4.

Simplify the design: eliminate second gable, eliminate the tacked-on triangles near the eaves, paint the garage the same color as the house. The paint colors should be attractive, not sad.

Rather than having the same architectural features with just different paint colors, have you considered having houses with different architectural features (even though they may be the same plan design)?

There are some good suggestions in the posts above.

The proportions seem all off. I can't figure out how a car will fit into the garage.

I prefer the color scheme of #4 but would prefer a horizontal siding.

For a relatively small façade, there are too many angles, shapes, colors, adornments, and materials. Keep it unified and simple to be calm and visually pleasing.
