Back of the house remodel

This is a scribble of my basic idea out back. I'm thinking that on the second floor, we should just improve the existing shed dormer structure and leave it the same size. The first floor may be roughly the size indicated by the outline. Improvements would be: remodeling the upstairs bath, replacing the tub with a shower. Downstairs: Remodeling the kitchen and adding a screen porch, remodeling the master bedroom and adding a nice bath there. Moving the laundry room to the area currently occupied by the bath. Putting a 1/2 guest bath where the laundry currently is. On top of all this, replacing the windows, shoring up the sagging framing, excavating out the right side of the porch and the basement steps. Repairing the damaged structure there and construction of new basement steps in an enclosure. My quest is to produce three plans: Cheap, not so cheap and whole hog for this work. Then I get realistic construction cost estimates for these projects and realistic appraisals for the value these projects will add to the property.
