Hello,
where do you actually want to build?
We are talking past each other, at least if your above question is directed at me.
Since visualized statements are usually easier to understand, I have tried to clarify what I mean in the attachment. I am not talking about later expanding the OG => upper floor (then you would also be planning a two-story house), but the attic (attic) that arises with the corresponding roof pitch (DN) and depth of the house structure. You speak of a small house of about 100 sqm, so it is probably a classic one-story house consisting of EG (ground floor) and DG (attic). The above parameters fulfilled, a space arises under the roof, called the attic or loft. Classically accessible via a pull-down ladder.
In my example, the attic is converted. However, you can carry out the expansion later step by step as DIY (EL); I do not assume that you plan a bathroom at the very top, so do not be confused by the drawing. For this, it is necessary that the living space staircase is extended to the attic, closed off with a living space door, and all lines in the attic above the wooden beam ceiling are routed and cut off there. Depending on the size of the house, you can gain a good 1 - 2 rooms using plasterboard (better than its reputation). If two children's rooms are already taken into account in the DG below, you have space for 3 children as planned.
In this way, you save yourself the effort of a later extension with an architect, structural engineering, and finding a company, and you have all the time in the world – even if one child is born quite soon – to expand the attic according to your wishes. The costs are limited to the extension of the staircase to the attic, a living space door, and somewhat longer electrical lines, possibly gas and water (underfloor heating); so manageable.
Oh yes – at the beginning and for the first years, the calculation for the KFW should purely relate to EG and DG. For this, the insulation is laid on the top floor ceiling; later you can relatively easily remove it again and instead pull it under the rafters and then cover it with plasterboard.
Rhenish regards


where do you actually want to build?
Is the expansion of the upper floor really more expensive than an extension?
It would of course really be worth considering building the house in the size you want to have it and only expanding upstairs in 10 years or when money is available.
