This looks sort of like a Colonial Revival (due to the color, shutters and balance) with a dash of Craftsman/Foursquare, and I would keep the windows and the operable shutters, although removing them from the bottom could be an option, and was common in the early 1900s. When was it built?

If you want to ramp up the Craftsman flavor, you could do the bottom in narrow horizontal siding and the top in shingle, and two tone it, darker on top than the bottom. Or stucco on bottom and shingles on top (I think I see stucco already and there are Hardie Plank stucco panels.) I do like the current color though. I like the current porch, although a beefier square column with a base, cap and bit of molding around the upper portion might be nice. The front door is a bit lost in shadow, so some light colored accents might be nice there, along with a reflective white or light blue ceiling.

A full length porch might be nice, possibly with a hip roof or extending out with a pergola over the garage. It would interfere with the window box though. I think some simple carriage style garage doors, or at least some with windows could be nice.

If you do alter the porch, I pay close attention to the detailing, and take a look at old houses from about 1905-1925 for inspiration. Some integrated latticework (not the plastic stuff) with "windows" might be a nice touch if you have the space, or it could be done in the garden.

With concrete cement it is really important to install a quality rainscreen behind the siding and on top of the housewrap to allow it to drain trapped moisture, have joints caulked and get the best contractor you can for the best workmanship. Could be a good time to insulate as well, at least a little. This may affect the window casings.
