The shapes, proportion and scale of the house in the photo are very challenging. The house is symmetrical, but the gable in the center does not have the same shape, pitch or fascia detail. The proportions of the house make adding a porch form (roof) challenging, as PPF suggests. Finally the scale of the porch and any columns should be sympathetic to the rest of the house. The columns in the first photo are much too small, while those in the second and third photos are much to bulky. A very careful study is need to see if and how a sympathetic porch may be added. If it was my house, I might be looking at a horizontal arbor or trellis type porch with appropriate detailed and scaled columns, rather than any sort of pitched roof. Google porch trellis or arbor for ideas. Good luck on your project.

Why replace the hydrangea? You can cut them back in late fall to almost ground. Other bushes should be pruned this fall. Your garage doors would look better with the top panel in windows. I much prefer a single door with sidelights. This one style to consider. A black door with white sidelights would look good. Think you could even do a unit that leans craftsman.

I would suggest adding a wide band of trim just above where the tops of the columns meet the wall. This should give the illusion of a beam being supported by the columns. The columns seem a bit undersized. I think I would replace them but instead of plain square columns I would give them a brick base with a brick or stone cap. I "might" suggest painting the entire house the same color - brick and siding but you should really give some thought to that. Once painted, brick can never be unpainted. It is a lovely house and a great lot. I LOVE the mature trees. Good luck!

Adding anything to the fornt of this house will only add to the imbalance . That huge addition above the house is the problem it created a huge mess that IMO could only be fixed by removing it not addin more stuff to the front. Maybe a bit darker color for that part to even out the color and then some fabulous landscaping to take your eye down
