Small porch

Hi, 

I want to build a small porch on the back of the house. 

The image attached is how it will look with the exception of the return walls will be clad in Hardiboard and the brick plinth is the step

Structure would be timber, clad in hardiplank and a concrete tile roof.

Will I need foundations ? Im hoping I can sit  the whole thing on top of a brick and granite step (I put the step in so it's pretty solid!) 

I want to avoid any brick plinths too so can timbersole plate sit directly on the step
