My house has the 'front door' at basement level. Anyone coming in that
way would think the place is a right **** tip. There's a door on the
lower 'living' floor but it isn't obvious from the street. If I happen
to be in the basement when some religio-maniac or whatever comes onto
the property I open the 'front door' (which looks great from the
outside) and invite them in. They look round in wonderment because they
are effectively in a dirty old cellar. I bet they go away thinking the
whole place is like that.
