This is a wonderful passive-solar plan if you have the living areas facing the winter sun. Place it on either an insulated concrete slab, or a well-insulated floor covered with tile. My favourite plan is very similar to this, except on mine there is an al-fresco area where this Br 1 is. Slide the bathroom to the left, remove the en-suite and there's enough room for a good-sized main bedroom.
