It might be easier/cheaper to simply do the new door arrangement and not worry about a foyer addition.

We need the room & house needs a front entry. Front door opens directly into kitchen. Willing to put $ into it to make it right.

You good a good licensed architect to answer your questions.

Do you have a picture from farther back so we can see the whole house?

At the moment I do not, but the ranch side basically extends twice the distance.
