Pets name and nearest landmark??? Ours would be F!"£ing stupid animal fire station! Doesn't work somehow....I'm not sure about naming houses unless their is a reason to do so. I have already seen too many 1970's little boxes called Rivendell!
If you must have a name hows about something completely stupid like Fobeth (FOur BEdroomed Town House) - it's novel and possibly the kind of silly thing competition organisers like - particularly if it is for marketing purposes.
Have fun anyway
