Terrace planning, need support

Yes, in the height of summer. How many days are that in Germany? In Germany, you have considerably more days where you are happy about any warmth and any heat storage than days that are too warm. I really wouldn't base it on that.

I just thought that too.

On average, quite a lot. 600-800 hours of sunshine in summer (June-August) on average means 6.5-9 hours of sunshine every day. That will get warm...

Yes, on some days from June to August. But from March to June and September and October, you enjoy every day when the stones still give off some warmth because then you can sit outside.

It depends on where you live (here it is midsummer for 2.5-3 months) and (much more importantly!) when you want to use the terrace. If you only sit there in the evening anyway, warm paving can be an advantage when the sun is already around the corner. But evening sun and heat is too much. Our balcony with a WNW orientation is unusable for dinner at 6 or 7 in the high summer without shading because the sun is burning down and the concrete radiates heat from below.

A closed balcony, however, is not comparable to an open terrace where the wind can blow through.

Lake Constance is a windless spot, as there is rarely a breath of air in the height of summer. ;) I definitely cannot agree with the statement "in Germany it's almost always cold anyway." That may apply in northern Germany where the weather is usually lousy. If there is still wind on nice days, then it is certainly bearable even in the blazing sun. But if you are somewhere sheltered from the wind or simply there is no wind blowing, it quickly gets warm in the sun. You can also create a heat buildup through walls or tight buildings. For example, in the picture, I can see garages and a neighboring building that could block the wind. Or if the direction is right, they can even intensify a drafty funnel.

Got a few samples...

First thought:

No. 2 for driveway + paths
No. 3 for terrace

What do you think :-)?
