Flagstone Porch meets Concrete Slab

[Ms. Aesthetik]

We recently embarked on "Project Porch" looking to replace the sunken, breaking, wood porch our house came with, with a beautiful flagstone porch to last for years to come.
Upon removal of the planks we discovered that part of the porch was under a concrete slab. (see images).
Now, this would be fine, however, we wanted to put in a storm door and the concrete slab would give the stone a two inch height that we need to clear the door.

Method:
This link provides information about the method we were going to use to put in the flagstone. http://www.stoneplus.com/DIY/How-To-Build-A-Dry-Flagstone-Patio-s1.pdf
Is short, crushed stone and sand.

Challenges:
- While the majority of the porch can be laid using crushed stone and sand, the concrete slab poses a challenge for this method for the remainder of the porch.
- Laying flagstone on top of slab would not give clearance for a storm door as it would increase porch height by about 2 inches which brings us right back to where we started with the wood.
- The foundation of the house is a concrete slab.

Question:
- Can we break up the concrete slab enough to lay the stone in flush with the rest of the porch without disrupting the integrity of the entire foundation of the house?


Thank you for your responses in advance,

Sledgehammer. Doesn't look like you have that much to remove.  Carefull at the edges near the house though.  Can be done with a good chisel.

with your img tags, you can help viewability a lot by specifying a width or height for the image. These images are incomprehensible for me even on a laptop. Just put width=# of pixels or height=# of pixels inside the opening image tab. Then the forum software does the rest.

I can't make much sense of the huge images either, but it's likely the pour was added after the footers were done.  Just take a sledge or jackhammer to it.  If it looks like it was poured with the footer, take a circular saw with a masonry blade and cut a slot along the house entry first.
