Does it even make sense to run a building savings contract?

So I looked in the portal and I have two building savings contracts running. (Why ever 2, does that make any sense other than double the fee?) One is designed for up to 100k, of which you'll probably save 40k yourself, then a 60k loan at a fixed interest rate of 1.25%. Now that doesn't sound so bad per se. The other one is designed up to 36k, so I don't know exactly what the interest rate will be. The problem is that I don't actually plan on buying an apartment. I live in my own apartment in my house
