Shell construction, construction start autumn / winter

Hi,

once again on the topic of the shell construction in autumn/winter: We are building a semi-detached house in calcium silicate brick with a concrete basement (hollow wall elements). Our building permit is available, the pit is dug, next Monday the floor slab will be poured.

In your opinion, does it even make sense to start now? What do we need to pay attention to?

Thank you very much!

Stone by stone could become tight. The shell including windows and doors should be finished before winter. That would be practical.
