Temporary floor coverings

We will be building soon. We were faced with the choice of building our dream house 'belagsfertig' or a smaller house 'schlüsselfertig'. Since we would not have felt comfortable with the smaller option, we decided on the larger house. We understand that a lot of work will come now, but we prefer to live for a certain time in a partially constructed site rather than 30 years in a house that is not our dream house. The plan now is to finish the rooms one by one (and if it takes 4-5 more years until the guest room and the office are also perfect, that’s okay too).

Now we are looking for inexpensive and easy-to-lay floor coverings that we can use until we lay the final flooring in the rooms. Aesthetics and durability are absolutely secondary here. Of course, they should not be toxic. :-) They should also be easy to remove when the final flooring comes.

Can the rooms that will initially only be used as storage rooms simply have the screed left? Or is there a risk of damaging it too much? What about screed sealing? I am not quite clear about the costs here. On the one hand, I have read that sealing should definitely be done in rooms without any other floor covering. On the other hand, I have read that these coatings can cost up to 150 euros per square meter. Or is exposed screed and sealing something different? Basically, we can live with sealed screed for a while, since we are anyway toying with a certain industrial look.

Addendum: The coverings should be suitable for underfloor heating.

Nachtrag: Die Beläge sollten für eine Fußbodenheizung geeignet sein.

This already limits you a lot, since all floor coverings (to my knowledge) have to be glued down with underfloor heating. The effort of tearing them up is very high.

What is your "planned perfect" flooring supposed to look like?

In the end, it should be parquet. Because of the tearing out, I was thinking about the screed sealing. You can simply lay parquet over it later, can't you?

Affordable laminate. If it is only sufficient as a storage room anyway, a floating installation is enough. The effect of the underfloor heating is slightly reduced as a result. Alternatively, affordable linoleum? Also installed floating?

Instead of cheap laminate, I would take something reasonable and see it as a long-term solution. Is there such a thing as cheap linoleum? So far, I haven’t found any.
