Hi...  I'm not familiar here, but I think this is the sidewalk with surface=paving_stones.
But perhaps there is an other path more to the building?

If there is some green between the mainroad and the sidewalk we add thes separately. In case it;s a parallel path we tag sidewalk-right, left or both in the tagging of the mainroad. 

Up to you!  :)
