I agree no round topped windows, no grids . I do think a double door is a nice idea but you need to protect the guests standing at the door . I see asphalt right up the thr entry almose what is with thta? IMO what is really needed is some landscaping color and green stuff.

I must agree with @Patricia Colwell Consulting

I'm guessing you are in the South, I especially don't like that there is no foundation to anchor the building.

if it were mine, I'd add a water table of sorts & base to make it appear to be grounded.

I am wondering who would side a building like that.

The round topped windows peg your house as built in the '90's (maybe early 2000's), so no reason to keep them. The issue I see with your house is that it is traditionally shaped but the windows are modern. I assume they're casement windows. If you stay with casement windows then there really isn't any point in having grids. A front door with two sidelights is fine. I agree with the other commenters that there is too much asphalt in front.

Sorry, but it looks like a parking lot.

I'm no designer, but get some grass and landscaping in there. Change the siding to a different profile in strategic areas (possibly in center section in and around the entry way. If you ditch the ronund tops you'll wnat something in those gable ends, maybe gabel vents or a different siding type.

A canopy over the door would protect your door long term.

Your windows are fine. Skip any kind of grid. And leave the arches alone-- they echo the gable peaks. Square transoms would look awkward. If you must do something, either remove the transoms altogether or see if you can get triangles instead of arches.

A porch roof, like Beverly suggests, would be a major improvement both functionally and aesthetically.

But landscaping instead of a tarmac desert will do the most to improve your home's curb appeal.

I dont mind the arches, so I would leave them. No grids in the windows. I agree with all the others, that your house needs some landscaping instead of all that black driveway way up by the house.
