Pro's & Con's of canvas living

I'm starting to come around on the idea of pitching a tent in either Janine's or Deb's (thank you for the offer) front yard... cleaning would be a breeze, there's only 2 of us anyway so why would we need all that space of a non-canvas house, the dogs always sit or lay on us so they don't need much room, and I'm sure our landlords would do us a favourable deal on rent - maybe even in exchange for domestic duties.  The only downside I can see right now is that there aren't any trees on the estate to pee behind.  And it could get a little cold in winter.  And developers approval of the facade may be tricky!
