What exactly speaks against technology at the end of this corridor again?
This is a simple box of mental inflexibility, I'm afraid: the builders are already combining a main house from a one-piece design and an extension from a two-part
different model – now trying to transplant the technology from this extension as well intellectually (and calculation-wise) overwhelms the draftsmen.
I am surprised how few concepts there are for multi-generational houses.
There are more than in every fourth provider, I would say – but unfortunately almost always as a marketing buzzword or relabeling of a model from the modular system. The most common form is to sell a combination with a narrower semi-detached house as such a multi-generational house – at most with wheelchair turning circles lovingly drawn in the senior part, and in the wider semi-detached house the grandparents are on the ground floor, while the youth have the narrower ground floor and the entire upper house.
