THIS looks very promising.
I've also already built two floors high from Bruder-parts. For this I have made extra adpater.
Do you know that you can use the windowless walls as an intermediate floor?
Maybe I can take pictures of it.
Hi Ingo, you mean make floor like this ?
Station is made with parts only from two bruder halls because roof on the garage sits with his own weight only on that door parts, when i lift roof, doors falls down.
Do you have picture of you adapter ?

I hope the pictures are explanation enough. But please only screw the long side parts, otherwise it can not be disassembled anymore.
