It does not give desired result.
Getting Dof right in post for artsy stuff like this can be tricky. But with a zdeph pass you have much more freedom to do so in post. You can also do a levels adjustment for the house to be completely in focus and paint over a zdepth pass where the levels were adjusted to blur a maximum amount of forest.
Frischluft LensCare has a feature specifiacll dedicated for stretching the DepthOfField (meaning the sharp part) non-physically correct to get around exactly the problem of having either too much of the subject blurred or too little of the very close other detail.
Also offtopic:
Parents have much agriculture experience and the grass/tile combo will never work out IRL (unless it's fake grass), if you don't dedicate a specialist to do so. Have seen a similar grass/tile combo, although bigger in size with problems like: grass will grow non uniform - no way around that. Patches where people step on it - that will be gone in no time. Grass will start to nag on the stone tiles, when roots start to push a year or 2 in, unless reinforced to prevent that fun stuff. (remeber the pea in cement school experiment from biology :D ) and getting it cut down to be uniform in height will require some dude with siccors to to each grass tile by hand.
