Hello dear community,

we are currently planning a new building (KFW 55) in the style of a city villa with a hipped roof and are considering leaving out the intermediate ceiling between the upper floor and attic in some rooms completely or partially to create a loft-like space, maybe even on multiple levels. In that case, I would also invest more money in the roof insulation since we save on the intermediate ceiling :D
But what exactly is the temperature difference in a well-insulated new building? Will I then have a sauna at the ceiling and cold feet on the floor??? :confused: Do we have to expect a significant increase in heating costs or is it all not that bad nowadays?

I would be very grateful for your help and would appreciate hearing about your experiences.

Best regards
Judyyy

This design decision primarily affects the structural stability of the house. The elimination of ceilings as stiffening elements - [Scheibenwirkung] - increases the buckling load of wall panels. The horizontal bracing of the building can also become more complicated due to the -partially- missing ceiling panels. All of this is feasible but may result in significant additional effort for the structural engineering and shell construction in the form of stiffening concrete components. The typical prefab house provider, who aims to sell their standard models, charges a high price for such variations, if they are willing to accommodate them at all. If an architect is commissioned with a custom design, this is more feasible and is only limited by your budget.

Yes, we are planning the house with an architect.
Therefore, there are no limits for us there.

(I hope my text doesn't look weird to you as well, I'm currently just on the internet with my phone =) )

Regarding heat distribution: That may work better in new buildings, but in existing buildings, such high rooms are somewhat difficult to air condition. In winter, you have to heat the house properly for it to be warm downstairs, and upstairs it actually becomes like a sauna.... especially annoying when the bedrooms are upstairs....

Yes, but a new building does not defy physics (heat rises upwards) either =)

I also don’t want to create major disadvantages that I will regret later.

Best regards

It depends on how the heating is to be done... with underfloor heating it also gets nice and warm at the bottom... with radiators you get the described sauna effect
