The title is pretty self explanatory but I think a housing scenery designed around the unicorn spawn-area would be widely welcomed and appreciated among the players of Potterworld. Most of the scenery could just be the white and blue trees found there and if the building team wanted to take things a step further they could add unicorn statues or more of the stone runes (such as the one found in-front of the large tree). While this is in no way crucial to game-play, I myself would use this scenery and some people I have talked to have said the same.
