Hello.  I haven't read House of Leaves (I might, now) but I'm potentially interested in the concept for a RP.

So, I don't know if our styles will mesh, but I tend to like Sci-Fi and Fantasy RPs because of the world building.  Would you consider doing the house-is-bigger-on-the-inside idea in a slightly non-normal setting, like modern day with slight fantasy elements or else near-future?  

I think perhaps the reason you aren't getting many hits on this thread is because generally Advanced RP interest checks tend to present one idea for a roleplay, fairly well fleshed out, looking for a group of players to fill in roles.  Yours kind of feels like a 1x1 post-of-all-my-ideas kind of post.  Not that that's a bad thing.  (Insert smile emoticon to indicate the friendly nature of this paragraph.)
