Hello everyone,

we want to renovate our house. In this context, we are installing heating and insulation (there is none in the house). This reduces the room height to 2.30 meters.

Our house has a finished attic floor above the ground floor. Question 1 would be how we should design the ceiling between the ground floor and the upper floor.
Question 1, Option 1: To get more room height, we thought about exposing the supporting beams between the ground floor and the upper floor. This would give us 2.30 meters up to the beams and 2.5 meters up to the top edge of the beams.
Advantage: Preservation of the existing building fabric.
Disadvantages: (1) Preventive measures against creaking floors on the upper floor, (2) precise planning to improve acoustic performance, (3) only 2.3 meters clearance under the beams on the ground floor, (4) possible additional costs for acoustic treatment and anti-creak floors?
Question 1, Option 2: Since we will remove the upper floor/roof, it would also be possible to remove the beams between the ground floor and the upper floor, build one row of bricks, and then lay a concrete ceiling on top.
Advantages: Modern, acoustic performance is given through prior planning. Room height is freely definable.
Disadvantages: Costs for the roof, removal of the existing beams.

Have I overlooked anything here? So far, I have understood that Option 1 is possible but also involves additional costs. Hence the question whether Option 2 might be preferable, as it is possibly equally expensive but with definable advantages?

Question 2:
My second question concerns the structure between the upper floor and the roof. After we have finished the ground floor, a complete upper floor (without slopes) is to be built on top. Then a roof will be installed on the upper floor. My architect said that I would have to have a ring reinforcement cast in the last row of the upper floor. Additionally, a steel concrete ceiling would have to be placed on top to reinforce the house further. I understand it as flat straps being installed on the roof to ensure rigidity. Therefore, I do not understand why an additional concrete ceiling should be placed between the upper floor and the roof. I find a ceiling made of wooden beams and thermal insulation better, as this automatically creates a thermal insulation layer between the roof and the upper floor. What do you think? Can you understand the architect’s reasoning?

Question 3:
Could the beams currently between the ground floor and the upper floor maybe later be placed between the upper floor and the roof, or does this bring no additional benefits (in terms of costs), since the carpenters prefabricate a lot and working on the beams on site would even be more expensive for us?

I would be grateful for your feedback.!
