Is a fixed awning practical, or do a sun sail or cantilever umbrellas make more sense? Of course, an awning works well for blocking the midday sun around the summer solstice, but if you’re sitting on the terrace in the afternoon, evening, or after work, the sun is already shining at a very different angle. Assuming a 4m (13 feet) awning—which I believe is usually the maximum—and a mounting height above the patio door of about 2.60 meters (8.5 feet), you get the following approximate values:
June 21, 12:30 pm => Shadow length 1.41 meters (4.6 feet), so 2.59 meters (8.5 feet) of the terrace shaded
June 21, 4:30 pm => 1.15 meters (3.8 feet) of the terrace remains in the sun
June 21, 5:30 pm => From this point on, the awning is completely ineffective
August 21, 12:30 pm => 1.83 meters (6 feet) of the terrace remains in the sun
August 21, 4:33 pm => From this point on, the awning is completely ineffective
September 1, 1:00 pm => Even at the solar noon, less than 1.60 meters (5.2 feet) of shading remains
Based on these considerations, a sun sail significantly larger than 4 meters (13 feet) might be more practical, which could have a deep corner on the west side. Alternatively, cantilever umbrellas might be a better option since they can be adjusted flexibly.

Depending on the situation, houses may fit better or worse next to each other, don’t you think?Can you give an example of what you imagine a high-quality cantilever umbrella to be like? Especially if it’s supposed to be portable and not fixed in concrete.
What bothers me about these umbrellas is that they always provide shade where you don’t need it, and generally, the shaded area is too small. The base is constantly in the way, and if you position it “upright” to block the sun from your eyes, you’ll have a lot of trouble with the wind.

On a south-facing terrace, you can definitely expect some sun… Maybe you know the Simpsons episode where Mr. Burns blocks out the sun over Springfield… but let’s leave that aside.
For umbrellas, you should look up Schneider Bermuda online. Find a suitable location to ideally set it in concrete. These models are very versatile, even allowing almost vertical installation, and are not comparable to the usual cantilever umbrellas that rotate freely. They can be fixed in any direction.

We have a large patio umbrella, and the neighbors have an awning—both work great in their own way during the summer... the terraces are about twice the size of the shaded area and are both oriented to the south.
You get sun when you want it and shade when you need it... also, moving the lounge chair/chair/table (at most once a day) is no problem.
But I would also recommend placing the terrace simply on the east side, then you won’t have any issues with the sun and won’t need any shading.

For me, such an awning feels somewhat like a small garden or traditional home style.I wouldn’t want to judge that negatively, because the modern, lifeless, and rigidly stylish gardens with a lot of symmetry don’t really have anything to do with family gardens anymore.
It’s really cozy to sit underneath.
But I still stick to my suggestion of planting a tree.
Grym spent about 2.5 years working out his optimal floor plan. We don’t want to go through that again.
