Looking up all sets that have this piece in tan, had me guessing at Set #5771-1 Hillside House.
EDIT: At least two maybe a third set...
Looking at white fence in upper right corner of 2nd pic.
Set #3938 Andrea's Bunny House.
Again looking at that upper right hand corner of 2nd pic.
I spy with my little eye a tan cone that is not in the previous sets....
This part is Tower Roof W. Tiles and because its only made in 3 colors and as the other two available colors are black and lilac, this must be the sand green version. Color in the photo has a more blueish tint to it
This version is only used in two Harry Potter Hogwarts set:
4842-1: Hogwarts Castle
