Raise the living room floor level

Hello everyone,

our basement has a reinforced concrete ceiling, above which are the upper floor and the terrace. Since the terrace needs to be insulated, there is a height difference of about 25 cm between the terrace and the adjacent living area (kitchen, dining room) on the ground floor. Stairs at the doors to the terrace are naturally not very attractive; our builder is currently planning to fill this height difference with several layers of screed. Is this the most cost-effective option? For 225 sqm of area, 18,000 € (net) are currently planned for the screed; of which 115 sqm will have the multiple layers. Do you perhaps have cheaper alternatives? The house will be heated by underfloor heating. Thank you in advance.

Stairs on the terrace are great! A few seat cushions on them and they become the nicest seats!

The terrace is higher than the living room, therefore the stairs would have to be inside the house. On the terrace we would have no problem with stairs :) Unfortunately, it would be the other way around...

Sorry, the sentence reads incorrectly, it is a planned new build

Even and especially with a new building project, I would assume that the ground floor would rather not be stolen. In any case, the good news means that the botch is still only planned, that the heights can still be saved. Show the plans, then we can find the thinking error of the draftsman. Dark memories of a problem of the robber are creeping over me:
