To build big with stone, you will need a lot of iron for those beams.
stone pieces are a full unit wide. Even the floor pieces are 1 unit thick. This is in 1x1 wood floor tile units.

Using these dimensions as a guide if you "Overbuild" your wooden structure to accomodate future stone "inside the wooden frame..pieces latch a lot easier especially wall wood "squares" which are half the size of the larger stone wall piece
