Ow! my eyes...lol...well, let me start off by saying that i totally believe HDR photography can be used in any situation, even when you can get the dynamic range you want out of one exposure. its the look your going for ;D
your picture of the house looks like you either 1. need more exposures of the image or 2. you need to bump the contrast down, a lot. the foreground,bushes, and shadows of the house are all too dark, precisely the thing you're trying to negate with HDR. just throwing in my .02 cents.
