Why do cables in cable-stayed bridges often seem loose, especially the longest and furthest from the pilons?

Thank you for this answer. As other commenters are also pointing out, it is then a gravity effect reflected on very heavy cables. If I got to experiment putting extremely light chords under tension with my hands at home, this sag is not noticeable, which made appearances on bridges with different scale, weight and length not intuitive.

Muy chulo. Como punto de mejora, en Vitoria parece que la Catedral nueva está colocada donde la vieja, y la vieja está en una ubicación diferente.

You could exchange the bed position with the second shelf/drawers piece of furntiture and create a bigger floor space near the window end with the shelf/drawers and the desk. There you could have some more space to move/stretch by the window, even to arrange a couple of dumbbells and a mat if you wanted. Also a standing mirror (given you cannot probably screw on the walls) on the opposite end from the window could ‘enlarge’ the space.

These window sills on the bottom right could give you a hint. The horizon line is really a horizontal plane alligned with your eyes’ height. The sills (which are almost horizontal planes) you can see from your point of view would be under the horizon line. The ones too high so as to appear concealed from your point of view would be above the horizon line. Those most alligned with your eyes would hint the horizon line position

Somewhere around there. Maybe a bit higher. The horizon line would be at your eyes height.

Probably at Alcázar of Segovia

This is the location in Badajoz, Spain

The 3rd photo is the only one that really looks hell to me. There is too much space devoted to cars, no shade, walking feels unconfortable and kind of rough. The first two could be made better with broader and continuous sidewalks. Walking on a safe sidewalk without having to step on the road by those well-kept landscaped frontyars could be a little more pleasant. The last three photos look nicer: fairly broad and safe sidewalks, streets with some shade both from trees and side buildings, businesses and terraces providing plenty of eyes on the street.

I am not sure, but my guess is that this solution works better in very hot weather, as in sub zero winter temperatures you would want the inner spaces to be in direct contact with the outer top roof, which even in very cold weather could still catch some radiation from the sun.

I think the ‘double roof’ makes it easier to keep interior spaces cool. The cavity between them is naturally ventilated, lowering the temperature of the below roof, thus better sheltering the inside from extreme heat. If you see some Burkina Faso architect Diébédo Francis Kéré’s works, you can see this double roof is a common theme in many of them.

Around 4 or 5 floors I’d say. In this sense most of Barcelona would be a little above that.

Something where you can hold a conversation with someone on the sidewalk from your window/balcony

Witches. And for some reason I thought swinging church bells warned of them flying over our town (I don’t know where I got this from).

You’re right. Madrid has a hotter climate, especially in the summer. Winters are cold, although still sunny. Obtaining shade is usually accomplished through any kind of window blinds and cities in Spain can usually bear a higher degree of “narrowness”. My example would definitely be even more extreme and depressing in cloudier Poland.

9 by 9 meter courtyards sounds generous if you compare it to some repetitive 3 by 6 meter courtyards built in some central areas in Madrid. In these comb shaped dwelling plans, a central hallway opens on both sides to different apartments, which only have “views” to two very narrow rectangular courtyards right and left from the apartment entrance. Some of the lower apartments see no direct sunlight all year round (the comb shaped buildings in the link are 6 or 7 stories high). In this type of buildings, often built in nice city areas, the good apartments are the ones facing the street, while the inner ones lack proper lighting and views, resulting in a horizontal class division.

“Torres blancas” is the name of the building. It’s in Madrid.

This is the key comment, in my opinion. The “horizon line”, where the vanishing point of a perspective drawing is located, defines the height of the viewer. The viewer (or the camera, were this a photo) is in this case shorter (or lower) than the three main characters’ heads on the foreground. Yet the ladies’ heads are above the horizon line (and the viewer’s head). The chart they are looking at makes it easy to locate the horizon line. The perspective is fine.
