Create shade structure, or negative extrusion from top of building

[SandeepSabu]

Hello,

I am trying to create a shade structure that has a portion of the bottom and sides of the building cut away starting from the top of the building.  I have a footprint with height and I want the shade to be at the specified height and then come down from that height.  Also, I want to create four posts at the corners of the footprint.  Similar to the picture below.

Could someone please suggest ways I might do this?

Thank you!
