Not being familiar with what is winter hardy in your region, I hesitate to make a lot of specific recommendations. However, a few things to consider: Japanese maples are adaptable, but have only moderate to low tolerance for salt, so think about whether your road is salted in winter and where run-off goes when you are placing that tree. Basically, think about placing plants to connect your house to the land, so it looks like it is nestled into the setting rather than sitting atop it, and something to soften some of the edges. The large trees behind and alongside your home give you a good start on this. Evergreens will, of course, give you color and coverage year 'round, but don't overlook deciduous plants hardy in your region that will also provide winter interest, like winterberry holly (you'd need a male and a female), red twig dogwood, witch hazel. Plants native to your region are usually a good choice, as they are well-suited to the climate and have co-evolved with and support local wildlife (think birds, butterflies, bees, and a host of tiny beneficial insects that help control pest insects). Therefore, native plants usually (but not always) require less attention from you. There are many non-native plants, too, that will "play nicely" with your native choices. Choose plants that are well-suited to the site where they will be living. Consider the amount of sun/shade, moisture levels, wind conditions, and, very important: your soil. Best bet is to have a soil sample analyzed for structure, pH (acid/alkaline balance) and nutrients. Here in the U.S. we have our cooperative extension services, run by state universities, with offices in most counties that provide a wealth of information, including soil testing. Perhaps you have something similar? If not, then you can do some basic tests at home. Most common landscape and garden plants on the east coast of North America prefer slightly acid to neutral soil that drains well, but is rich enough in organic matter to retain some moisture and nutrients.

Here is the furniture from a picture of our old house. Is this hopeless with the style of the light over the kitchen table? BTW, I love the rose bushes idea and could put them behind the safety of the gate in the front courtyard. I will ask at the garden center what they advisee to put in front of the concrete wall because we have a nightly herd of deer out front. It's so much fun. And I know, it's wonderful to have those kinds of beautiful, happy dreams. I have never gardened much but can see how great it might be. The house can be beautiful. It's a little cold looking now, and I havent hot much talent in decor, but I think it could be warmer and more inviting. I would like to have a welcoming home.

I like the Greek Revival style of your home. Stay with that. Hopefully you can use the existing roof and extend it so that you have more of a wrap around porch.

I do not see a big issue with the side walls but you need to fill that space where there should be windows . So easy answer some type of trellis with evergreen type plant . IMO change the place for the closet or put windows in the closets . I love my window in my walk in closet. If these closets are just reach ins just put them on another wall. I guess I need to see the floor plan of the house to understand really where those closets are . Post the to scale plan here in a comment DO NOT start another post .Landscping will be ahuge improvement on curb appeal and for sure some different way to have guests know where the door even is. Are you out in the country or in town? I need more info for sure .Post all info here in comments.
