You want the building on the high spot and the ground sloping away to each side.
The roof is going to rain down water on the outdoor kennels unless you have gutter installed to take the water away. Soggy ground under kennels adds to smell.
High ground, sloping clay is best to build on...keep gutters free of leaves to prevent overflows.
What I'm trying to say is, divert water/drainage/run-off away from kennel, stay high and dry...
