Smart. Anti-microbial. Also, your house won't get blown over by the Big Bad Wolf. He can't knock over brick houses. And it will reflect the sun, so it won't get too hot in the summer. And it will ward away birds because they'll be scared of the light. And, pilots will know where you are if you need help because they'll just go to the shiny building. And, it will be made out of silver, and that's the greatest gift of them all. :P
