It's really got a lot going on and is anything but flat. If you're not used to looking at this type of drawing, they do look weird and flat. Can your architect sketch you up an angled view?

Consider replacing the arched window over the front door with a fair of double hungs that matches the adjacent pair.

You may actually be responding to the wrongness of the design and thinking it's flat, when that is not the problem. If anything, I would be looking to remove the smaller gable and the brick or stone under it (whatever material is intended there). It looks odd to emphasize a vertical area that doesn't include the front door. I would flatten the center gable or eliminate it. Is there some reason the windows on the right are paired together instead of singles like the other side? While you don't need to be a slave to symmetry (the garage is already throwing off the symmetry), unless there's a good reason to have different windows it looks like a mistake. The window over the front door looks like something from the '90's. In fact the whole design looks like something from the '90's. I love traditional, but if you like it too, go more traditional and don't repeat mistakes from thirty years ago.

While everyone hates the look of a garage, this one isn't bad because it isn't positioned in front of the bulk of the house. If you eliminate the gables, make the portico more interesting and then you will have a beautiful, classic, traditional home. If you can afford to put brick or stone on the front, do the whole front, don't piecemeal it.

It’s not as flat as you think.

What do the sides and rear look like? I hope as much attention is paid to them.

PPF much better

Design the house, do NOT design an elevation.

Get nicer looking garage doors and skip the windows. The garage doors are about 1/4 of your front facade, so spend a proportionate budget on them.

I think you need to ask your architect for an angled view. What you have is an elevation - that is one dimensional. It gives you no sense of what the front of the house will look like.

You won’t be able to judge the 3 dimensional massing of the design with a 2D construction drawing. Can’t your designer provide a 3D computer model?
I haven’t designed a building without a 3D computer model since 1990 and I made balsa wood models before that.
