That's a big question.

Depending on your interpretation of the genre, Dieselpunk covers a lot of territory. (Personally, I think it spans from the start of the Great War to the end advent of the atomic bomb at the end of WWII.) But when it comes to architecture specifically, I tend to think of Art Deco as being most emblematic of the Diesel style.

In the real world, I tend to think of the Chrysler Building in New York as the quintessential Deco skyscraper:

Seen here with the Empire State Building, also an example of Dieselpunk Deco architecture (though not quite as dramatic):

New York didn't have the market cornered on this style; Google 'art deco architecture' and you'll see that almost every American city had a hotel, bank or department store in this style. Here's a beautiful example, the old Union Terminal in Cincinnati, Ohio:

(Which as far as I'm concerned was immortalized in another great American city.

Haha.)

The history that never quite was also provides some excellent examples of Dieselpunk buildings, notably the Palace of the Soviets:

..and just about anything designed by Hugh Ferriss:

And there were some downright fantastical ones, many of which turned up in the pages of Popular Science and Mechanix Illustrated, like this amazing gem from Benjamin Goodwin Seielstad:

Check out my Architecture tag, you'll find more examples (as well as other stuff) there.

Hope that was an interesting, if brief, tour of the subject of Dieselpunk buildings.

GAS GIANT LIFE FORMS. 

This startlingly clear telepathograph was lifted from Institute clairvoyant Hans-Ulf Codrescu at our Romanian office, showing life-forms he visualized after a 48-hour spell of concentration. These life-forms (whether they possess intelligence or not is unknown at present) evolved on the small gas giant X181 orbiting in the Goldilocks Zone of Fomalhaut, an exciting star system for the discovery of life from which the Institute has already received radio transmissions that have been resolved into another photograph. Although present-day space travel is depressingly slow, clairvoyant methods of investigation (at present only held by one known body on Earth, namely The Institute in its two dozen surviving offices) have been shown to be frustrating but effective.

I've always been partial to the Palace of the Soviets.

I have tags for soviet and Soviet Union, though at least some of that might overlap with my atompunk tag.

And check out the Soviet Space Dogs!

G.H. Davis was born in London in 1881. He received a formal art education and was already working as a freelance artist before World War I. He served on the Royal Air Force putting his talent to good use creating aerial diagrams for pilot training. After the war he continued his career as a freelance artist specialized on military subjects, and in 1923 he started his 40-year collaboration with the Illustrated London News. By his own estimate he created more than 2,500 pages of illustrations over a 40-year span, many of them consisting of very detailed technical cutaways of military planes, ships, submarines, and tanks.

Apparently it's no joke.
