Cellar in the site

I have a small plot. When I moved here to a permanent place of residence, I discovered a completely decent house, abandoned vegetable garden and a failed cellar. The garden cleared, silent, supported. He began to grow vegetables.
Little Land has been restored, and the harvest year from the year becomes better and better. The question arose about where to store it until spring. It was impossible to restore the old cellar, I decided to make a new one. Found on the site a suitable place (a fairly steep slope) and began to dig a pit. The case was not easy, as I wanted to pull out a fairly deep cellar, so as not to walk in it bent.
Kotlovan made oblong so that there was a place for a gentle step (2.5 × 4.5 m). On top to the pit laid a log. Made a grout of chopped straw and clay, cooled them, and then flooded the earth (approximately 50 cm), but before in the logs cut the hole for the ventilation pipe.
The walls of the cellar was crushed. On the floor laid the crushed stone with a layer of 10 cm, poured it with a hot bitumen. And from above made global coating. Clay kneaded with straw, covered in several layers. The ground floor for the cellast is the best, it contributes to the retention in the repository of the desired atmosphere. I was convinced of this on my own experience: I never dry vegetables, not wither.
By the way, I don't keep anything in the floor - I bought fasteners wholesale, I chisted wooden grids so that the air is circulated under the boxes and bags with vegetables, all connected and attached to the wall.
But the steps made concrete, with the help of formwork. In the cement-sandy solution added fine crushed stone.
When the internal works were finished, built over the cellar of a double roof from wooden boards. Skates lowered to the ground level. The roof is more pitted, overlaps it with 40 cm on each side, which means that the rainwater in the cellar will not be faded. He spent through the roof in the cellar of the ventilation asbocate pipe, closed its upper end with a metal "umbrella" from the rain.
Put the door out of thick boards, it was well insulated with a thick foam rubber, angered by the canlenka.
I have been using this cellar for 12 years, no problems during this time arose.
