You can still play a Stonewall Attack when Black decides to castle kingside with the bishop fianchetto.
Black reacts with d5
Here is an example with "normal" moves from Black.
[FEN ""]
1. d4 Nf6 2. e3 g6 3. Bd3 Bg7 4. f4 d5 5.Nf3 c5 6. c3 O-O 7. O-O Nc6
The stonewall attack is a solid opening with grip in the center:
- White controls the important central squares (
d4
, and e5
)
- White can install a knight in
e5
which will force Black to weaken its position if it wants to remove it.
- White can play this typical manoeuvre to exchange the bad bishop in
c1 against the knight in f6 by playing
Bc1-d2-e1-h4
.
- With a closed center, White can then expand on the king's side with
g4
...
Here is an example with black normal moves that are a bit cooperative!

Black reacts with d6
The setup with d6
suggested by @user1583209 is very clever. d6
is a flexible move that allows Black to counter-attack with e5. Here is an example where Black is okay:

1. d4 Nf6 2. e3 g6 3. Bd3 Bg7 4. f4 d6 5. Nf3 O-O 6. O-O Nc6 7. c3 e5
I would suggest reacting with 7.e4
instead of 7.c3
like in this game (obtained by transposition)
