Hello Webmaster-uk
I have been doing a similar project on my own for 2 years and am close to completion.
It’s called Klimakeller! Size approx. (external dimensions) 480cm x 430cm. I got 13 containers of 10m² each. That’s about 4,000 euros. For the pit, I concreted curbstones (100 x 25 x 5 cm) upright as edging and for the formwork of the floor slab. On the floor, I laid overlapping stud foil. The floor slab consists of fiber-reinforced WU concrete, 30 cm thick. The walls are made of 30 cm concrete formwork blocks. I laid the first row of these blocks flat on mortar. Then in the middle of each block a hole (d=14mm) and vertically 14mm reinforcing steel bars 1 meter long. 3 blocks stacked and each filled with concrete (1:3). Don’t forget to put an 8mm reinforcing steel bar horizontally in every row of blocks. This up to the top and also the vertical reinforcement to the top. Here applies: more is better. On top then a ring beam and now I am forming the ceiling. I do the reinforcement according to the structural engineer’s plan. Concrete about 30cm. For sealing: thick-layer bitumen, 5cm styrofoam (the rigid type) on top of that and stud foil again in front.
Between wall and curbstones I filled with filling gravel, between curbstone and soil RCL. Always compact well. I extended the curbstones to the top (after all over 3 meters).
I wouldn’t do it without approval. Such a cellar can be approved without problems. A structural engineer is a must.
I do it myself for fun. Hiring someone you cannot afford. But I think I will manage with 10,000 euros.
If you have questions, also gladly via PM.
