Homescapes rendering

Hey guys, Im wondering, how it is possible to achieve the same rendering as it is Homescapes?

In short words, there seems to be 2d isometric sprite(most likely tilemap) used for background, and there should also be a 3d character, that walks on top of this sprite.

tilemap might have no rotation, and orthographic camera might look on scene from top. This will work, but no with 3d, as in such setup, user would see the player from top as well, while in Homescapes, we see character from 30* degrees angle, like from the side.

Any advices?
