Regular price!
We have paid / did pay: in total just under 60,000 € for an 8.22 x 10.22 m basement (with drainage / welding membrane, therefore no white tank or similar).
About 51,000 € are for the basement including excavation (about 6200 €), including 4 windows + light wells, including stairs, including ceiling with recesses according to plan, including inspection shaft, including soakaway shaft, etc. More or less pretty much everything all in (also including pipe installation ON the property).
In addition (and this is how we reach the 60,000) are the disposal / storage of topsoil / excavation / shrubbery, which cannot be stored on our (small) property (another 5500 € extra) as well as various other small items (lifting system, etc.).
