In loosing the front door and facade of my building, I have learned the hard way the important services a facade provides:
-- Shelter from the rain (The remnants of Hurricane Hanna came through the other day)
-- Protection from dust and street dirt
-- An interface with the public. (No facade means no buzzer or apartment numbers. Try explaining that to the delivery guy.)

-- ...and a blank slate for graffiti artists
Recently we regained a front door, and we are looking forward to a facade in the near future.
