@rosydruid a lot of buildings have cut-out holes at the bottom that look like grass so they can blend in more
the way u placed urs is a bit low i think it needs to be higher

here's an example from one of my scenes, not the same building but it functions the same way lol. you can see the grass cutouts at the bottom (tho they look kinda weird in winter, they look much better in other seasons)
you can also add other buildings and decor to ground it in, like what ive done with the stone garden
