Let me start at the beginning. Here's a view of the southern façade of my house, taken in November 1993 (several months before I became the official owner of the property):
A long time ago, I asked René Uzel to remove that linden tree, along with the old apple tree that you can see on the left-hand edge of the photo. Since then, the southern façade of my house has been clearly visible, as you can see from this photo that I took this morning:
Here's a closeup photo of the entrance at the southern end of the cellar, taken a month ago from the top of the short earthen ramp that leads down from the level of the outside ground:
The next morning, I was able to examine closely the mechanism of the electric motor in my concrete mixer, and I discovered that the old cam belt was in perfect shape. The cause of the breakdown was a simple bolt that had escaped from the motor shaft, enabling the small cog to drop off. And, five minutes later, I was able to insert a new bolt, tighten it and get the machine running perfectly. Funnily enough, when I went back sheepishly to the hardware store in order to return the new cam belt and ask for a refund, I was received once again as a genuine "tradie" (as Aussies say). Not only had I taken apart the motor of my concrete mixer, but I had been able to detect an unexpected problem and repair it effortlessly. The fellow at the counter found it perfectly normal to refund the cam belt.
Finally, I used two bags of cement to lay enough concrete for the threshold, and the final result is perfectly acceptable.
The concrete slab might appear to be exceptionally thick. In fact, it needed to be a little higher than the level of the future elevated wooden planking that I intend to install (once I've finished the construction of the wood oven) throughout the entire cellar, which measures 6 meters long (from north to south) and 4 meters wide (from east to west).
Yesterday, a carpenter from Pont-en-Royans dropped in to take measurements for a door at this place. Later on, I intend to build a concrete staircase from the threshold up to the level of the outside ground. It will be composed of exactly 9 steps, each of a so-called rise (height ) of 17 cm and a so-called run (depth) of 25 cm. See, I'm already starting to talk, once again, like a genuine tradesman. I must be careful not to get a swollen head, otherwise my tradesman's hard hat will no longer fit on my skull.
