You have a beautiful house, but it could use some exterior improvements.

The front of the house only has a huge driveway as the entry element......It could use a wide sidewalk in a nice paving material to the front porch.........The driveway would look a lot better if it were in an interlocking paving material rather then a concrete slab............

The house would benefit from the help of a landscape architect. You can have them do conceptual sketches for you that you could slowly make happen over time.....

A white picket fence across the front of the house would make a huge difference too......

The back yard is totally disconnected from the house...........A deck off the back with new french doors would be a great addition to the house......with stairs down to the yard.......and maybe a paved area with a fire pit and BBQ.

As i mentioned before, a landscape architect would be able to make some amazing suggestions for you.........

Where are you located ? If i had to guess I might say North Carolina......

Looking at the rear elevation as well as the garage side elevation, an upper deck with walk around to the front porch will be both useful and also tone down the transition at the basement and first level.
