Not sure what your budget is, but one option is to rebuild the front covered entry and have it span the entire width of the house, and consider repeating this basic form in future additions such as a garage if there isn't one already.

Bought an old home...I loving refer to as my retirement bank..124 years old. If your husband or you have any carpenter skills or a family member who loves you a lot...look for old doors that includes barn doors that are too large...cut them down or refigure to size...its custom. You did it...wood is thicker and better....paint them all the same color....instant character. Or start with the one that is the worse problem...see how it goes...mine are beautiful...add something different and built to last. Most were $25.00 to $50.00 except the front door..but new doors they are thin...not real wood and to me cheap . its work to sand strip and measure ....make sure to measure about five times...keep in mind old homes are not square...but for us it worked...old doors you pick up for almost nothing aren't either. I made paper doors to take with me to lay on top of old doors to see how it would be...that wasn't easy but used old cardboard first and butcher paper taped together I could fold and take. You can check the height of the door knob which is important I found out..we have a door that we mismeasured and it like a dutch door I think they call them top opens and bottom opens or together..it goes from kitchen to dinning room so like a pass through. Which worked out to look good but what a headache..so the butcher paper template is a must. You are in for a lot of work and fun...as long as you know. Just about anything can be changed someway to work...diy magazines and web sites are educational...good tools...borrowed or hope for as a gift a blessing...renting if your sure you can get it done in a day is an option. Lots of info...custom doors start at least at 200 where I live uninstalled not real wood...for us this made sense...not for everyone...we love our house or recycled doors.good luck...doing it make you love it more.

I think the first layout is fine. You might want to consider moving the door for the storage room of the master bedroom so that it opens into the hall. That way the kids can use it for overflow storage. Also, that hallway is big enough that I think it could hold a large armour, providing more closet space. (There's no need to sleep in the same room as your clothes, so long as they're not too far off.) Also, don't forget that while the drawing shows kids in double beds, this need not be the case, so there will be more room for furniture (dressers or whatever) in their rooms. Finally, that step to bedroom 4 will not be odd at all. I've seen it in other homes. It looks clumsy in the drawing but it isn't. What you'll see when you come up the stairs is a bedroom door on a slight diagonal. It's only an odd jagged step if you walk like a robot, in straight lines along the wall, which is what your eye is doing on the drawing but you won't do in real life.

What kind of flooring alternatives are you looking for?
