I've been progressing through my house re-doing everything Bill did (it's almost done), however, I didn't expect even he could bodge a septic tank. Wrong again! It turns out that he only built two brick walls in it and the other two sides are starting to collapse! Please, people, if you see him avoid him. Under the whitewashed walls there was not a single piece of work he did for me that was any good.
Check the pictures in my part of the site gallery to make sure you know who I'm talking about.
You can see my house here. I'll upload some pictures of the new kitchen and roof soon:
