The modified Hogsmeade village uses 877 pieces; of which there are 97 extra pieces and the rest are from the official set 76388. The design mashes the 2 buildings into a 16×32 baseplate and increases their height and overall look to match the scale of the Diagon Alley set. In doing so, this modification can be built as an extension of Diagon Alley.
Depending on the location of this mod in a Harry Potter scene, further improvements can be made such as using dark bluish gray baseplate and removing the white pieces (snow) and placing dark tan tiles and plates on the pavement.

Modified Harry Potter set building instructions only, no actual bricks included
