Door House/Garage: Side entrance door as a fire protection door?

Exactly. Without these two options at the side entrance door.

I have meanwhile received feedback from our GÜ. The transition to the garage does not have to be T30/T90, a normal side entrance door is sufficient.

Happy Bavaria, but better check this information yourself!

You just have to consider if that is enough for you?

For example, if your car catches fire in the garage, then a side entrance door might not offer you much protection.

And if a burglar gets into your garage, he can comfortably try the door until he opens it. No one can see him....

Fire protection:
yes, I would definitely install a networked smoke detector.

Burglary:
Exactly for this reason we want the side entrance door, because it is also available with triple locking and automatic mechanism.
That means the door locks itself automatically when it closes.
I think it is unrealistic to believe that you always keep this door locked if you have to do it with a key.

For the thousand euros that an automatic surcharge costs, I would rather install electronic monitoring - it might be easier.

At the front we also have an engine lock, but the T30 door remains a simple door.
