One of my "dream houses".  This one is designed for a particular hill on the the land that once belonged to my mother's family, hence the "Heritage" name.  It's designed around the compass points.  Come to think of it, so is Terra Alpha.  Huh.  Anyway, the idea is to have gratuitous amounts of natural light without overheating the interior.  I've done a CADD version of this but can't seem to find it at the moment.
