Consider going across the front of the house with a porch. I think the overhanging 2nd floor will be an issue with just a portico. Also remove the shutters from the bow window and the upstairs double window, they look odd.

What is done, has been done, in "remuddle"

Not sure how all the interior information relates to the question of improving the look of the entry, other than to say..........

Leave it alone, put the money into landscaping: ) and the awkward stair entry.

I've seen discussions on here previously about off centered entryway doors under a portico, it happens. But not sure what purpose you need it for since there's already an overhang. If it bothers you that there's more space on the right of the door, below are some ideas with planters. I also covered the shutters on the right to just see what it would look like.

I would save up some money and do a full front porch like jck910 suggested. I would not waste my money otherwise. I would also consider taking the window left of the front door and making it into part of the door with side lites since I believe you said it was part of the foyer.

I agree a full porch might help your curb appeal, but I am bothered most by your lack of a roof line in the front elevation. It makes the home appear squatty.

For what it's worth, first period colonial houses frequently had uneven or asymmetrical bays, because they were added onto lengthwise. They started out, for example as three bay houses with the door to one side and the chimney on one end. Then the bays would be added to the chimney end of the house, and since the chimneys were massive, the houses usually ended up asymmetrical as a result.

They started out like this: (1718)

And would be added onto like this. This was probably three bays on the right with the two bays on the left added with a bigger space next to the door because of the fireplaces. (1718)

Or this: (1720)

The left of this house is 1671, the right is 1710 or 1734.

Your house does not have the proportions of these, but it shows that this style of house did not necessarily dictate symmetry. I think the problem with your house is that it is a garrison house.

I did find one photo of a colonial Revival house (1930s) that has both a garrison and a portico:

Colonial Revival houses were pretty much strictly symmetrical and put the fireplace where it was better for decorative fires (and the furnace) but technically it's inauthentic because it's at the end of the house instead of the middle.

Here's one with a portico, also not symmetrical

I would probably replace the bay window on yours with a flat window if I were to attempt a portico design.

I don't remember seeing a lot of this type of Colonials or Colonial revivals with portico. Of course I may have just missed them. As another poster said a full porch across the front of your home might be a better option. It would provide you with more outdoor living space.

Good point about the bay window, thanks!

Thanks everyone! The front porch was about 7x the cost of the portico... so it's not in the cards right now. That said, I found some old plans, and we had considered putting the door where that other window is in the foyer - so that could still be an option... but maybe just freshening up with really good landscaping will give it what it needs. Appreciate the feedback!!!

The pitch on the canopy should not be any greater than the pitch on your house.
