Is a garage interior depth of 570 cm sufficient for future cars?

You can get used to working with centimeters, but it’s not fun. And it’s not practical either. The way you’ve drawn it, you can already start padding the corner in the equipment room. And I hope your wife doesn’t fit the cliché ;)
The mirror on the Superb is due after half a year, and you can also pad the wall at the very front.

Männer! :D

Because of the trailer hitch or because of the length? ;)

if the floor area ratio is tight, why don't you leave out the equipment room and make the garage wider by that amount, parking is more relaxed and equipment can also be hung on the wall

You mean width 5.5m and length/depth 5.6m? That's then similar to mine (5.7m length x 5.3m width internal dimension). Could you maybe take a photo and show how it looks, or send it to me via PM? (Make the license plate unrecognizable). Can you still load the SMAX in the garage at the back if you drive it all the way to the front?

I will, but it's currently not inside because I'm working on the motorcycle.
Still, don't forget to increase the floor area ratio if you have space and consider compensatory measures like a green roof or permeable paving. Or specify the terrace much smaller and then build it bigger anyway, etc.

...And when the family then comes home with the SUV/station wagon, at least the front passenger must get out in front of the garage. The same applies conversely when leaving.

and of course in any weather :eek:

With the front passengers it's still okay if someone gets out first - for example, one of us regularly travels with a toddler in the rear-facing child seat - and that one is behind the front passenger seat.

With that size, I would simply plan for one car to stay outside - done

what's up, why such an evil smiley?
