I would keep the siding all one color; separate-colored corner boards and water tables would make the small house look too busy and boxy. I have a ranch and I am having siding added that is all one color, including corner-boards. You could do a pretty-colored trim, along these lines: Look at how happy she looks. All smiley. I could see your house as a cream color with colorful trim. Or a very light sage green siding with a deeper green trim?? So essentially tone-on-tone. As for that big space you're worried about, if it's west-facing an arbor can help block the western sun for that room. Or you could put up a trellis? But honestly, not every large space "needs something." Some areas benefit from "negative space" to allow that eye to rest. Especially if you're working on landscaping. Plan to have cottage-style the landscaping do most of the "charm" work for you. Maybe even window boxes if you're very good about watering them? You could actually put pots of annuals in there and then change them out as they reach the end of their usefulness. Just a thought. I would remove those stones around the tree and I don't think the post light belongs. The main issue, for me, is the inability to identify the location of the front door from the head-on view. A great new mailbox, and nice, large house numbers, pretty, low shrub or pots of colorful flowers helps to draw the eye to the entry Look at etsy for house numbers. You have an easy house to work with. Lucky!

I struggle with the clay tile roof, which to me calls out as Mediterranean, and swiss anything but then again I’ve never been to Switzerland. I wonder if anyone more knowledgeable can confirm or set me straight on that? Setting that aside, doesn’t this house beg to be a southwestern ranch? Won’t anything else look Disneyish? Again, I call out to those more knowledgeable about architecture.

Whats your budget? Your home even with copper looks classic and the yard/landscape looks clean and well kept. Its not fancy but it's not hurting . If you are going to do a big update roof and stuff in 3-5 years. I would decide my future design /color and invest in the door now. The home looks good the only issues with curb appeal is the door. IMO The original door probably had rot and they replaced on the cheap with a standard 36 inch and walled up the difference

I love the current green, and the yellow front door! The uniformity of the green allows the garage car-doors and people-door to blend in. I'd remove the fence unless it is serving a purpose (which I don't see). For safety, ensure the visibility of your house numbers from the street. Is there anything you'd like to add out front, such as a sitting space, a cover or a bench near either door? (I don't see the need for anything, it's just what functionality you would like.) For landscaping suggestions, re-post your picture, include your planting zone, the direction your house faces (East?), and a nearby major city so that people can make practical recommendations, and hope that a professional gives you a pretty picture to go by :-) Nice house!
