What an interesting roofline! Are you a fan of the bricks or do you want to do something to change the look of those, like cladding?

What kind of budget do you have in mind?

Yes skillion, will you build it in front of the existing carport & separate?

Well it does look out of sorts with the house but if it could be used & the carport built in front then you won't see it. As an approved structure it might be worth converting it to anything you like, even dare I say a tool shed/storage. Do you have room to leave it for the carport build ??

analyze first, then plan

My analysis from your photo, is that you have a not very inviting front entrance area, and I would have to walk down your driveway to reach it, or park in the drive and block your cars entering or leaving. But you have asked us to comment on two problems that you have identified. A wish to double your garage, and a desire to improve the curb appeal from within your neighborhood.

It appears that the simple solution, dollarwise, would be to just extend the garage roof to the left to add another bay. And, to improve the entrance area, remove that porch railing in order to bring guests in, away from the vehicles, and put up a wall, or at least a lath screen on the right side of the garage, but a wall will block odors and heat from the autos as well.

Move the water hose from the front to behind the fence or into the garage.

To my eye, the white wood at the front porch looks DIY, homemade, unprofessional, and the white paint draws our eye to it first, so find a darker color, please.

Is there a wall between the house and the street?

I would like you to have your guests park on the street and meander toward the house on a pedestrian path, perhaps from the side of the nice plant bed we see.

A further enhancement to the curb view, would be a pleasant pair of outdoor chairs and a small table, in front of the brickwork, an arrival terrace for you to have morning coffee with your neighbor, or to make such an appearance of generosity. The entrance path could be directed there and then over to the entry porch.

If you win the Lottery, I suggest you build a new garage up at street level at your property line, and use the present carport area as an entrance terrace for your daughters to entertain their friends, with plants beyond and screening the rear of the garage.

Good luck
