I'm lucky in this respect, too.
Recently broke up with my gf of some 5 years, and have house to self to indulge in all day/night.
Mind you, prior to that, we were both heavy cig smokers indoors (50+ sticks each per day).
After 20 years of smoking cigs more or less continuously I have, in the last 2 weeks, migrated back to the (non inhaling) pipe smoking for 90% of my daily needs (I tend to smoke about 5 - 6 1/2 filled bowls spaced throughout the day to keep on top of the tail end of my nicotine cravings, with maybe 3 - 5 cigs thrown in the routine).
Want to be 100% exclusive to the pipes by next weekend, and would like to arrive at a point of ~3 full bowls per day (breakfast/afternoon/post-dinner) within a month or so.
My brother, who is an ex smoker, visited tonight for a few drinks, and he was quite pleased to finally be with me in a house where all he got was the odd wiff of a Dunhill EMP or Petersons University Flake, rather than a half pack of cig smoke second-handed onto his clothing. Funnily enough, he was the one who got me into pipes back in our teen years
Having said all that, will have to let this place go shortly, as I can't afford the bills solo, so will bunk at my folks' for awhile, in which case I'll be outside to light up...
