I was going to do that too! (for the kakariko village in my game... which is MC <__<)
Anyways, the bottom looks nice (maybe a different door if its a casual house, and a /little/ smaller. but what you have is good for an office-type building), but I think that the roof looks a little too bare. Actually, when compared to the roofs on MC houses it almost isn't even MC style, but I'd say add bricks around all the edges, or shingles (sp?) like normal houses, adding a shine or something to the roof, or maybe panneling or whatever.
