Okay, so digging wasn't really the first step in creating a wood-stove Addition.

With input from Mark's mom (and due to the relative cheapness of large, glass patio doors when compared to double-glazed windows), we decided to make the new room cover the area where our problematic, blows-open-if-you-don't-lock-it, leaky door currently is.

Which means the real step one was moving the cat flap to the other door.

Phase two was taking down the landing and steps we installed just shy of a year ago.

Now we're ready to dig!
