Costs for renovation of a condominium

Hello!

My boyfriend and I want to move into an apartment in his grandparents' house. Unfortunately, everything is quite old... We probably still have a lot to do, but we don't know what kind of costs will come our way. It is certain that the bathroom needs to be completely renovated, and we would like to move a wall to make the bathroom a bit bigger (currently only about 5-6sqm). Since the wall is load-bearing, a steel beam would have to be installed. Ideally, we would like to have both a bathtub and a shower. The flooring would definitely need to be renewed as well (preferably: parquet in the living, sleeping, and working rooms, and tiles in the hallway and kitchen), the walls, and possibly the doors. For the doors, we are considering just painting them. The apartment is about 80sqm in size. Most of the work would be done by ourselves and acquaintances. Can someone help us and give us an approximate estimate? We are completely inexperienced... :( We would appreciate it. Thank you!

Hello Merenwen,

just keep your hands off load-bearing walls!! First call in a structural engineer. Parquet will cost around 25-50 € per m2, paint and primer will probably cost a few hundred if you paint yourselves and can live with the result later ;) The bathroom will come to about 15-20k depending on tiles and fixtures. Since you are inexperienced as you write, you will need professional companies here.

Thank you for the response! We are lucky to have many in the family and among acquaintances who have experience with conversions or even a craft profession in this field, so hopefully the costs for specialist companies will be avoided. Then it probably means saving up... :(
