Renovation of the basement for use as a laundry room and storage

We would like to renovate our basement with an area of approximately 35 m2 so that a washing machine and dryer can be used there and for storing moving boxes with contents. Attached are two photos of the current condition of the basement floor as well as the basement walls with mold. Currently, no ventilation or similar system is installed.

What cost-effective renovation measures can you recommend for the basement floor as well as the basement walls with mold, in order to use a washing machine and dryer there and additionally store moving boxes with contents? Grinding the floor? What measures for the floor? I assume that a ventilation system definitely needs to be installed. Thank you very much!

I would only store boxes in the basement of a modern new building with heating. In old buildings, mold is otherwise inevitable.

By applying liquid plastic, mold and moisture could also be controlled
