I was wondering if someone could help explain this to me. I have googled it and it says if you exit your house and stand in the garden with your back to the house and your compass points south, then your garden is south facing. But why is that so important? Surely if you are in anything but a south facing garden you can just position yourself or your chair so you are south facing. Also how does a south facing garden apparently get more sun? Is it because your house isn’t blocking the sun? Because even if your house doesn’t block the sun, your neighbours probably will.
