Two granite steps for the front door

Hi, this is Alex in Sandyford.

As you can see from the photo with the white house, the black door is 25 cm above the ground, and in front of the door there is a niche that is lower than the door.

What needs to be done: 1). fill the niche to the level of the door (so that I can move the door forward), 2). and extend this level to get 2 steps 3). finish the steps with granite or similar stone.

I have added a picture with an example of the steps, what result I would like to get.

Thanks!
Alex
